Professional Negligence in Correctional Settings: The Standard of Care, MICRA, § 364 and § 340.5

Scope and warning#

This page addresses California state-law claims for professional negligence arising from medical, nursing, mental-health and related care delivered to patients in county jails, state prisons and other correctional facilities in California, including care delivered by county employees, by employees of private correctional-health contractors, and by outside providers to whom patients are sent. It addresses the classification of the claim, the standard of care, the MICRA statutes, the public-entity immunities that are specific to prisoners, and the distinction between contractor and public-employee clinicians. It does not address the constitutional claims (Roadmaps 042, 043, 044), wrongful-death and survival procedure (Roadmap 065), the detailed mechanics of the Government Claims Act (Roadmaps 078, 079, 131), causation doctrine in depth (Roadmap 075), expert-witness practice in depth (Roadmap 074), or damages in depth (Roadmaps 076, 096.2).

Several authorities remain description-level; the direct California Legislature pages for §§ 340.5, 364, 3333.2 and 845.6 could not be authenticated through this research interface (403/inaccessible). The 2025 codified statutory texts quoted for these sections were inspected on Justia reproductions; these are reproduced statutory text, not direct official California authentication. California Courts’ official 2026 CACI edition and July 2026 supplement were identified by the Judicial Branch index, but the complete official instruction PDFs have not been independently authenticated for each quotation on this page. Court-opinion reproductions are distinguished in the source log. Nothing here is legal advice. The Medical Injury Compensation Reform Act was substantially amended effective January 1, 2023, and older commentary and older forms may state superseded figures. Nothing here applies a statute to any person's facts or states when any period began or ends.

The factual situation this roadmap addresses#

A generic hypothetical. A 46-year-old man is held pretrial in a county jail. He has a history of high blood pressure and has been without his usual medication since booking. On his third day he submits a health-care request form stating that he has a severe headache and blurred vision. A licensed vocational nurse sees him that afternoon at sick call, records a blood pressure far above the threshold at which the facility's written nursing protocol directs the nurse to contact the on-call provider, gives a single dose of an oral medication that the protocol authorizes, and schedules him for the next routine provider clinic, which is several days away. The chart does not show that the on-call provider was called. That night the housing officer notes in the unit log that the man is "confused" and "not making sense" and returns him to his cell. Early the next morning he is found on the floor of his cell, unable to speak clearly or move his right side. He is taken by ambulance to an outside hospital, where a hemorrhagic stroke is diagnosed. He survives with lasting deficits.

The jail's health care is delivered under a contract between the county and a private correctional-health company; the nurse's employer, the on-call provider's employer and the contractual relationships among the entities are unknown to the man. After his release he obtains some of his records, and a family member asks whether anything can be done. Every person and fact in this hypothetical is invented. It is used only to show how the law organizes the questions.

Governing law#

Professional negligence is negligence measured by a professional standard

California does not recognize two different torts called "ordinary negligence" and "professional negligence." In Flowers v. Torrance Memorial Hospital Medical Center (1994) 8 Cal.4th 992, a patient left on a gurney fell when a nurse "raised only the far side railing," and the question was whether the claim had to be pleaded and proved as one kind of negligence or the other. The Supreme Court held that "with respect to questions of substantive law they comprise essentially one form of action" (AR-066-C01). It explained that "a defendant has only one duty, measured by one standard of care, under any given circumstances" (p. 1000), that "only one standard of care obtains under a particular set of facts" (p. 998), and that the "nature of the alleged breach of duty affects only the determination of the appropriate standard of care" (p. 997). (Grade: Settled.)

Professional status changes the measure of care, not the duty. Where the defendant is a professional, the measure is the skill and care of the profession — in Flowers's words, "the knowledge, skill and care ordinarily possessed and employed by members of the profession" (p. 998). The CACI Sources and Authority note to the medical-negligence instruction summarizes Flowers to the same effect: "specialized education and training do not serve to impose an increased duty of care," and labeling a claim professional negligence "does not transmute its underlying character" (CACI No. 500, Sources and Authority; AR-066-G01). (Grade: Settled.)

Why, then, does the label matter? Flowers answered that too: "Any distinction between "ordinary" and "professional" negligence has relevance primarily when the Legislature has statutorily modified, restricted, or otherwise conditioned some aspect" of malpractice actions (p. 998). The MICRA statutes are those modifications. Each uses the same statutory definition: "Professional negligence" means "a negligent act or omission to act by a health care provider in the rendering of professional services, which act or omission is the proximate cause of a personal injury or wrongful death, provided that such services are within the scope of services for which the provider is licensed and which are not within any restriction imposed by the licensing agency or licensed hospital" (Code Civ. Proc. § 340.5, AR-069-S06; the same definition, without the leading article, appears in § 364, AR-096-S04, and Civ. Code § 3333.2(j)(4), AR-0961-S03). Whether an act occurred "in the rendering of professional services" decides whether the shorter limitation period, the notice requirement, the damages limits, the fee limits and the punitive-damages procedure apply. The CACI note records the Court of Appeal's view in Bellamy v. Appellate Department (1996) 50 Cal.App.4th 797 that the statutory definition "focuses on whether the negligence occurs in the rendering of professional services, rather than whether a high or low level of skill is required" (not opened; description level, as quoted in CACI No. 500; citation as shown there). (Grade: Settled as to the statutory definition; Majority/likely as to its application to borderline acts.)

In custody, classification sorts actors and acts, but does not mechanically establish every element. Nursing triage of blood pressure, a provider consultation decision, a physician telephone order, medication administration and licensed mental-health assessments ordinarily involve professional services. Whether a specific alleged negligent act satisfies the applicable MICRA definition depends on the defendant’s qualifying licensure, scope of service, causal theory and the particular statute; some institutional or custodial acts require a separate classification. A housing officer's decision about whether to call for medical help is not; custody officers are not licensed health-care providers, and their duty to summon care is a creature of Gov. Code § 845.6, discussed below. Some acts sit at the border — an injury in a medical unit's bed, a fall during an escort to the clinic, a missed transport to an outside appointment — and the classification of those acts is a counsel question that the Flowers and Bellamy line governs. (Grade: Analytical inference.)

The standard of care and its expression in the CACI 500 series

The Judicial Council’s CACI instructions supply recommended jury formulations, subject to case-specific modification and the governing authorities. The Judicial Branch identifies a 2026 edition adopted in December 2025 and a 2026 supplement adopted in July 2026; this review confirmed their existence from the official index but did not re-check every quoted instruction against the July supplement. The elements of negligence are that the defendant "was negligent," that the plaintiff "was harmed," and that the defendant's "negligence was a substantial factor in causing" the harm (CACI No. 400); the Directions for Use to CACI No. 500 direct that "medical" or "professional" be inserted before "negligence" in a malpractice case, and that the standard-of-care instruction for the defendant's category of professional be given with it (AR-066-G01). (Grade: Settled as the pattern instruction; the instructions are approved by the Judicial Council and their Sources and Authority are commentary, not holdings.)

For a non-specialist physician, the standard is that the defendant "fails to use the level of skill, knowledge, and care in diagnosis and treatment that other reasonably careful [insert type of medical practitioners] would use in the same or similar circumstances," and "This level of skill, knowledge, and care is sometimes referred to as "the standard of care."" (CACI No. 501; AR-066-G02). A specialist is measured against the skill, knowledge and care that "other reasonably careful [insert type of medical specialists]" "would use in similar circumstances" (CACI No. 502; AR-066-G03). A nurse is measured against other nurses: the nurse "is negligent if [he/she/nonbinary pronoun] fails to use the level of skill, knowledge, and care in diagnosis and treatment that other reasonably careful [insert type of nurses] would use in similar circumstances" (CACI No. 504; AR-066-G04). The Sources and Authority to CACI No. 504 quote Lattimore v. Dickey (2015) 239 Cal.App.4th 959 for the proposition that "[A] nurse's conduct must not be measured by the standard of care required of a physician or surgeon" (description level, as quoted in CACI; citation as shown there). The distinction matters in custody, where licensed vocational nurses, registered nurses, nurse practitioners and physician assistants perform much of the front-line assessment: each is measured against the standard of practitioners of the same kind, and an expert must address the right kind. (Grade: Settled as the pattern instructions.)

Three further instructions shape custody malpractice cases. First, CACI No. 506 tells the jury that a practitioner "is not necessarily negligent just because [he/she/nonbinary pronoun] chooses one medically accepted method of treatment or diagnosis and it turns out that another medically accepted method would have been a better choice" (AR-066-G05). Its Sources note that the instruction is given only where there is expert testimony that the defendant chose a medically accepted method among alternatives (Ayala v. Arroyo Vista Family Health Center (2008) 160 Cal.App.4th 1350, description level; citation as shown in CACI). The malpractice analogue of the constitutional "difference of medical opinion" rule is therefore narrower than the constitutional rule (Analytical inference): it protects a choice between accepted methods, not a choice that no accepted method supports. Second, CACI No. 508 states the duty to refer: "If a reasonably careful [insert type of medical practitioner] in the same situation would have referred" the patient to a specialist, the defendant "was negligent if [he/she/nonbinary pronoun] did not do so," unless the defendant "treated [name of patient] with as much skill and care as a reasonable [insert type of medical specialist] would have" (AR-066-G06). Its Sources record that the instruction may apply to a nurse's failure to consult the attending physician where that failure departs from nursing standards (Fraijo v. Hartland Hospital (1979) 99 Cal.App.3d 331, description level). In a jail, where the nurse at sick call may be the gatekeeper to the physician, that may be the central breach theory (Analytical inference). Third, CACI No. 514 states an institutional duty for hospitals: "A hospital is negligent if it does not use reasonable care toward its patients," and "A hospital must provide procedures, policies, facilities, supplies, and qualified personnel reasonably necessary for the treatment of its patients" (AR-066-G07). The Directions state that the instruction "is not intended if the hospital is being sued based on the negligence of an agent or employee." Whether CACI No. 514 or an analogous institutional duty applies to a jail medical unit or to a correctional-health contractor that is not a licensed hospital is a counsel question; the instruction is drafted for hospitals. (Grade: Settled as the pattern instructions; Analytical inference and counsel question as to the application of CACI No. 514 to non-hospital correctional providers.)

The standard is the profession's standard "in the same or similar circumstances"

Whether correctional medicine has its own, different standard of care is a question readers frequently ask and courts rarely answer in terms. The instructions measure the defendant against practitioners of the same kind "in the same or similar circumstances" (CACI No. 501) or "in similar circumstances" (CACI Nos. 502, 504). The Sources and Authority to CACI No. 501 quote Avivi v. Centro Medico Urgente Medical Center (2008) 159 Cal.App.4th 463: "The test for determining familiarity with the standard of care is knowledge of similar conditions," and "Geographical location may be a factor considered in making that determination," but by itself "does not provide a practical basis for measuring similar circumstances." The same note quotes Borrayo v. Avery (2016) 2 Cal.App.5th 304 for the proposition that "neither the Evidence Code nor Supreme Court precedent requires an expert witness to have practiced" in a particular locality (description level for Borrayo; citation as shown in CACI). The Title 15 minimum standards for local detention facilities reserve clinical judgments to the responsible health-care professionals (Cal. Code Regs., tit. 15, § 1200; AR-031-R01), which is consistent with a clinical, not custodial, measure of clinical decisions. Nothing opened for this page establishes a distinct, lower "correctional" standard of care in California malpractice law. The setting — limited on-site diagnostics, security constraints on movement, the need to transport off site — is plausibly among the "circumstances" an expert may take into account, and defendants will argue it; whether and how far it changes what reasonable care required is a fact question for experts and the jury. (Grade: Settled as to the "same or similar circumstances" formulation; Analytical inference as to the custody setting; counsel question.) Roadmap 074 addresses how experts present that question, and Roadmap 088 how accreditation standards and Title 15 may be used as evidence.

Proving the standard: expert testimony is ordinarily required

Because the standard of care is a professional standard, it is ordinarily proven by experts. Flowers, quoting the Supreme Court's earlier decision in Landeros v. Flood, states the rule and its exception: the standard must be shown by experts "unless the conduct required by the particular circumstances is within the common knowledge of the layman" (p. 1001). Munro v. Regents of University of California (1989) 215 Cal.App.3d 977, quoting the same passage, states that the standard of care "presents the basic issue in a malpractice action and can only be proved by their testimony" (p. 984), and states the summary-judgment consequence: when a defendant moves for summary judgment supported by expert declarations that the care met the standard, the defendant "is entitled to summary judgment unless the plaintiff comes forward with conflicting expert evidence" (p. 985, quoting Hutchinson v. United States) (AR-066-C05). The CACI No. 501 Sources quote Scott v. Rayhrer for the general rule — "As a general rule, the testimony of an expert witness is required in every professional negligence case" — and describe the common-knowledge exception as narrow: "This exception is, however, a limited one" (Scott v. Rayhrer (2010) 185 Cal.App.4th 1535; description level, as quoted in CACI; citation as shown there). The Directions for Use to CACI No. 501 add that the instruction's expert-only paragraph is used where "expert testimony is necessary to establish the standard of care, which is usually the case" (AR-066-G02). For nurses, the CACI No. 504 Sources quote Massey v. Mercy Medical Center Redding (2009) 180 Cal.App.4th 690: expert opinion is required "except in cases where the negligence is obvious to laymen" (description level). (Grade: Settled.)

The practical meaning for a custody case is that a malpractice claim is built from the beginning around a qualified expert who has reviewed the complete record — not around the patient's sense that the care was wrong. A claim that cannot obtain a supportive expert review is not ordinarily a viable malpractice claim, however bad the outcome. Roadmap 074 explains expert qualification, disclosure (Code Civ. Proc. § 2034.210 et seq.), the gatekeeping standard of Sargon Enterprises v. University of Southern California, and the federal counterpart in Fed. R. Evid. 702 as amended effective December 1, 2023.

Causation and the natural course of disease

The causation element is that the negligence "was a substantial factor in causing" the harm (CACI No. 400). The Sources to CACI No. 500 quote Belfiore-Braman v. Rotenberg (2018) 25 Cal.App.5th 234 for the rule that "causation in actions arising from medical negligence must be proven" within a reasonable medical probability based on competent expert testimony, while the Directions state that the jury need not be instructed in those terms (AR-066-G01; Belfiore-Braman at description level). The Legislature has added a specific limit: "No health care provider shall be liable for professional negligence or malpractice for any occurrence or result solely on the basis that the occurrence or result was caused by the natural course of a disease or condition, or was the natural or expected result of reasonable treatment rendered for the disease or condition," but the section "shall not be construed so as to limit liability for the failure to inform of the risks of treatment or failure to accept treatment, or for negligent diagnosis or treatment or the negligent failure to diagnose or treat" (Civ. Code § 1714.8; AR-066-S05). In a delay case, therefore, the question is not whether the disease would have progressed but whether a timely, non-negligent response would more probably than not have changed the result. Roadmap 075 addresses causation doctrine in depth, including lost-chance arguments. (Grade: Settled as to statute text; Majority/likely as to the reasonable-medical-probability formulation.)

MICRA: the statutory overlay

Who is a "health care provider." Each MICRA statute defines its own reach. Code Civ. Proc. §§ 340.5 and 364, Civ. Code § 3333.1 and Code Civ. Proc. § 667.7 define "health care provider" as "any person licensed or certified pursuant to Division 2 (commencing with Section 500) of the Business and Professions Code," persons licensed under the Osteopathic and Chiropractic Initiative Acts and Health & Safety Code chapter 2.5, "and any clinic, health dispensary, or health facility, licensed pursuant to Division 2 (commencing with Section 1200) of the Health and Safety Code," and state that the term "includes the legal representatives of a health care provider" (AR-069-S06; AR-096-S04; AR-066-S02; AR-066-S03). The 2022 amendments gave Civ. Code § 3333.2 a broader definition: "health care provider" "includes the legal representatives of a health care provider and the health care provider's employer, professional corporation, partnership, or other form of legally recognized professional practice organization," and a separate "health care institution" category covers facilities licensed under Health & Safety Code chapter 2 (commencing with § 1250) and "all persons and entities for which vicarious liability theories, including, but not limited to, the doctrines of respondeat superior, actual agency, and ostensible agency, may apply" (§ 3333.2(j)(1)–(2); AR-0961-S03). (Grade: Settled as to text.)

Two consequences follow in custody, each an analytical inference that counsel must confirm. First, physicians, nurses, physician assistants, psychologists and other licensed clinicians are health-care providers under every MICRA statute. A private correctional-health company that employs them is within § 3333.2's definition as their "employer"; whether the same company, if it is not itself licensed, is a "health care provider" for §§ 340.5, 364, 3333.1 and 667.7, whose definitions do not mention employers, is a question this page flags rather than answers. (Grade: Analytical inference; counsel question.) Second, a jail's medical unit may or may not be a licensed health facility. The Health and Safety Code defines a "correctional treatment center" as a licensed health facility operated by the state corrections department or by a county, city or city-and-county law-enforcement agency that "provides inpatient health services to that portion of the inmate population" who do not require general acute care, and states that the definition "shall not apply to those areas of a law enforcement facility that houses inmates or wards" who may be receiving outpatient services and are housed separately for improved access to care (Health & Saf. Code § 1250(j); AR-073-S06). Whether a particular jail's infirmary is a licensed correctional treatment center is a public-record fact (Roadmaps 087, 098); if it is, it falls within the "health facility" language of the MICRA definitions and within § 3333.2's "health care institution" category. (Grade: Settled as to text; Analytical inference as to application.)

Noneconomic damages (Civ. Code § 3333.2, as amended). The injured plaintiff "shall be entitled to recover noneconomic losses to compensate for pain, suffering, inconvenience, physical impairment, disfigurement and other nonpecuniary damage, subject to the limitations in this section" (§ 3333.2(a)). For actions not involving wrongful death, liability for noneconomic losses against health-care providers collectively "shall not exceed three hundred fifty thousand dollars ($350,000), regardless of the number of health care providers," with a separate and equal limit for health-care institutions collectively and a third for unaffiliated providers or institutions whose separate and independent negligence occurred at, or in relation to medical transport to, an unaffiliated institution (§ 3333.2(b)(1)–(3)). For wrongful death the corresponding figures are $500,000 per category (§ 3333.2(c)). No provider defendant and no institution defendant is liable in more than one category (§ 3333.2(d)–(e)). The section "shall apply to all cases filed or arbitrations demanded on or after, January 1, 2023"; the non-death amounts "shall increase by forty thousand dollars ($40,000) each January 1st for 10 years up to seven hundred fifty thousand dollars ($750,000)," and the wrongful-death amounts by $50,000 each January 1 for ten years up to $1,000,000; "The dollar amount in effect at the time of judgment, arbitration award, or settlement shall apply"; and from January 1, 2034, the $750,000 and $1,000,000 figures are adjusted for inflation by 2 percent annually (§ 3333.2(g)–(h)). "Unaffiliated" is defined by reference to employment, contract, ownership, joint venture and health-system relationships, determined "at the time of the professional negligence" (§ 3333.2(j)(3)). (AR-0961-S03.) (Grade: Settled as to text.) For a judgment, arbitration award or settlement taking place in calendar 2026, the statute’s unadjusted annual schedule yields $470,000 for a non-wrongful-death claim and $650,000 for wrongful death per potentially applicable collective category (2023 baseline plus three annual increments). These are not per-employee multipliers, nor an automatic total of three caps. A third category requires the separate-and-independent negligence and unaffiliated-institution conditions in subdivision (b)(3) or (c)(3). The amount at the time of judgment, award or settlement, not simply filing, governs; 2027 or later resolution requires recalculation and official statutory confirmation. The limits do not apply to economic damages — medical expenses, lost earnings, the cost of future care — which remain recoverable in full on proof.

In custody the categories matter in a specific way. In the hypothetical, the jail clinicians and their employer would fall in the provider category; a licensed correctional treatment center, if one were involved, could fall in the institution category; and the outside hospital might qualify as unaffiliated only if the statutory affiliation criteria, institution setting, and separate-and-independent negligent conduct are independently proven; a different building, transport episode, or company name does not by itself create a third cap. Whether a county, a contractor and a professional corporation are "affiliated" with one another for § 3333.2 purposes is a contract-and-records question (Roadmaps 086, 101). (Grade: Analytical inference.)

Collateral sources (Civ. Code § 3333.1). "In the event the defendant so elects, in an action for personal injury against a health care provider based upon professional negligence, he may introduce evidence of any amount payable as a benefit to the plaintiff as a result of the personal injury" under Social Security, disability or workers' compensation acts, health or disability insurance, and health-care service contracts; the plaintiff may then introduce what the plaintiff paid to secure those benefits; and "No source of collateral benefits introduced pursuant to subdivision (a) shall recover any amount against the plaintiff nor shall it be subrogated to the rights of the plaintiff against a defendant" (§ 3333.1(a)–(b); AR-066-S02). (Grade: Settled as to text.) For a patient whose post-release care is paid by Medi-Cal or another public program, the collateral-source election must be distinguished from statutory lien or reimbursement rights; this excerpt does not establish that a public payer loses every independent statutory recovery right. Counsel must check the relevant federal and California reimbursement statutes and lien notices.

Periodic payments (Code Civ. Proc. § 667.7). "In any action for injury or damages against a provider of health care services, a superior court shall, at the request of either party, enter a judgment ordering that money damages or its equivalent for future damages of the judgment creditor be paid in whole or in part by periodic payments rather than by a lump-sum payment if the award equals or exceeds two hundred fifty thousand dollars ($250,000) in future damages" (§ 667.7(a); AR-066-S03). The court must make a specific finding of the periodic amounts, may require a judgment debtor who is not adequately insured to post security, and must specify recipients, amounts, intervals and number or period of payments; "money damages awarded for loss of future earnings shall not be reduced or payments terminated by reason of the death of the judgment creditor," but are paid to persons to whom the creditor owed a duty of support. "Future damages" "includes damages for future medical treatment, care or custody, loss of future earnings, loss of bodily function, or future pain and suffering of the judgment creditor." (Grade: Settled as to text.)

Punitive damages (Code Civ. Proc. § 425.13). "In any action for damages arising out of the professional negligence of a health care provider, no claim for punitive damages shall be included in a complaint or other pleading unless the court enters an order allowing an amended pleading that includes a claim for punitive damages to be filed." The court may allow it on a showing "that the plaintiff has established that there is a substantial probability that the plaintiff will prevail on the claim pursuant to Section 3294 of the Civil Code," and may not grant the motion if it "is not filed within two years after the complaint or initial pleading is filed or not less than nine months before the date the matter is first set for trial, whichever is earlier" (§ 425.13(a); AR-066-S06). (Grade: Settled as to text.) Whether a particular claim "aris[es] out of" professional negligence for § 425.13 purposes, as distinct from an intentional tort by a health-care provider, is a classification question for counsel. Public entities are not liable for punitive damages under California law (Gov. Code § 818, not opened; description level).

Contingency fees (Bus. & Prof. Code § 6146). "An attorney shall not contract for or collect a contingency fee for representing any person seeking damages in connection with an action for injury or damage against a health care provider based upon such person's alleged professional negligence in excess of the following limits": "Twenty-five percent of the dollar amount recovered if the recovery is pursuant to settlement agreement and release of all claims executed by all parties thereto prior to a civil complaint or demand for arbitration being filed"; "Thirty-three percent of the dollar amount recovered if the recovery is pursuant to settlement, arbitration, or judgment after a civil complaint or demand for arbitration is filed"; and, if the action is tried or arbitrated, counsel may move for a higher fee "based on evidence establishing good cause" (§ 6146(a)(1)–(3); AR-066-S04; R1 AR-S912). Periodic payments under § 667.7 are valued for fee purposes on the plaintiff's projected life expectancy (§ 6146(b)). (Grade: Settled as to text.) The limits shape which cases counsel can take, which is one reason a complete, organized record matters (Roadmap 009).

The ninety-day notice of intent (Code Civ. Proc. § 364)

"No action based upon the health care provider's professional negligence may be commenced unless the defendant has been given at least 90 days' prior notice of the intention to commence the action" (§ 364(a); AR-096-S04). "No particular form of notice is required, but it shall notify the defendant of the legal basis of the claim and the type of loss sustained, including with specificity the nature of the injuries suffered" (§ 364(b)). It may be served as prescribed in Code Civ. Proc. § 1010 et seq. (§ 364(c)). "If the notice is served within 90 days of the expiration of the applicable statute of limitations, the time for the commencement of the action shall be extended 90 days from the service of the notice" (§ 364(d)). The section does not apply "with respect to any defendant whose name is unknown to the plaintiff at the time of filing the complaint and who is identified therein by a fictitious name, as provided in Section 474" (§ 364(e)). (Grade: Settled as to text.)

The California Supreme Court construed subdivision (d) as an extension/tolling mechanism in the circumstances before it. Its holding does not establish that a § 364 notice extends a Government Claims Act presentation deadline, or that serving only a medical provider substitutes for presenting a government claim. In Woods v. Young (1991) 53 Cal.3d 315, it held that when the notice is served within the last ninety days of the one-year period of § 340.5, "the 1-year statute of limitations is tolled for 90 days" (p. 319; see p. 328) (AR-066-C02). (Grade: Settled.) The consequence of failing to give the notice is stated in Code Civ. Proc. § 365: "Failure to comply with this chapter shall not invalidate any proceedings of any court of this state, nor shall it affect the jurisdiction of the court to render a judgment therein," but an attorney's failure to comply "shall be grounds for professional discipline" (AR-066-S07); Woods describes the notice requirement as one that "is not jurisdictional and does not invalidate any proceedings" (p. 326). (Grade: Settled.) That a noncompliant action is not void does not make the notice optional; it is a statutory precondition, and serving it on every known provider defendant is the prudent course. (Grade: Analytical inference.)

Where a provider defendant is also a public entity or a public employee, the notice of intent and the Government Claims Act claim interact. In Phillips v. Desert Hospital District (1989) 49 Cal.3d 699, a § 364 notice served on a public hospital district that disclosed a claim for money and a likely lawsuit "must be treated as a defective "claim" activating the notice and defense-waiver provisions of the act" (p. 708); "a document constitutes a "claim as presented" triggering sections 910.8, 911 and 911.3" when it discloses the claimant's demand for money and that suit will follow if the demand is not paid, and an entity that does not give the statutory notice of insufficiency waives defenses based on the insufficiency (pp. 709, 711) (AR-078-C03). (Grade: Settled.) Phillips addresses a particular document received by the public entity identifying a monetary claim and threatened litigation, which triggered defective-claim notice and waiver procedures; it is not a holding that every § 364 letter sent to any clinician, contractor, or address counts as a government claim. Treat it as a narrow safety-net argument, not a safe filing plan: a document intended as a Government Claims Act claim should be prepared and presented as one (Gov. Code § 910, AR-131-S01; Model 131), and the timing interaction between § 364(d), § 911.2 and § 945.6 in public-entity cases is a counsel question addressed in Roadmaps 078 and 082.

The limitation period (Code Civ. Proc. § 340.5) and imprisonment tolling

"In an action for injury or death against a health care provider based upon such person's alleged professional negligence, the time for the commencement of action shall be three years after the date of injury or one year after the plaintiff discovers, or through the use of reasonable diligence should have discovered, the injury, whichever occurs first. In no event shall the time for commencement of legal action exceed three years unless tolled for any of the following: (1) upon proof of fraud, (2) intentional concealment, or (3) the presence of a foreign body, which has no therapeutic or diagnostic purpose or effect, in the person of the injured person" (§ 340.5; AR-069-S06). The same statute specifies different minor rules: generally three years from the allegedly wrongful act, with a longer option for a child under six up to the eighth birthday; its express parental/guardian–provider/insurer fraud-or-collusion tolling provision must be read separately. No age-based calculation should be inferred here. (Grade: Settled as to reproduced statute; application not analyzed.) The one-year period runs from discovery of the injury, and California courts treat discovery as including awareness, actual or constructive, of the injury's negligent cause; the details of accrual and discovery are addressed in Roadmaps 008 and 082. (Grade: Majority/likely; accrual authorities not opened for this page.)

Custody raises the question whether imprisonment tolls § 340.5. Code Civ. Proc. § 352.1(a) provides that if a person entitled to bring an action is, when it accrues, "imprisoned on a criminal charge, or in execution under the sentence of a criminal court for a term less than for life, the time of that disability is not a part of the time limited for the commencement of the action, not to exceed two years" (R1 AR-S603). In Belton v. Bowers Ambulance Service (1999) 20 Cal.4th 928, the Supreme Court held that § 352.1 can toll the one-year period of § 340.5 but not its three-year outer limit: "No tolling provision outside of MICRA can extend the three-year maximum time period" (p. 931), and "We see no reason to apply the second sentence of section 340.5 to the one-year period it does not mention" (p. 934) (AR-066-C03). (Grade: Settled.) Two further limits apply. Section 352.1 "does not apply to an action against a public entity or public employee upon a cause of action for which a claim is required to be presented" under the Government Claims Act (§ 352.1(b); AR-068-S02). And whether "imprisoned on a criminal charge" reaches pretrial detention in a county jail is disputed: the Court of Appeal in Austin v. Medicis (2018) 21 Cal.App.5th 577 read it to mean imprisonment in state prison after conviction (R1 AR-C50), while the Ninth Circuit's earlier reading of the predecessor statute in Elliott v. City of Union City treated continuous post-arrest custody as sufficient (R1 AR-C49). (Grade: Unsettled/split.) No reader in pretrial custody should assume that custody extends any period.

The public-entity overlay: the prisoner immunities and their malpractice carve-outs

Who is a prisoner. For the immunity chapter of the Claims Act, "“prisoner” includes an inmate of a prison, jail, or penal or correctional facility," and "a lawfully arrested person who is brought into a law enforcement facility for the purpose of being booked ... becomes a prisoner, as a matter of law, upon his or her initial entry into a prison, jail, or penal or correctional facility, pursuant to penal processes" (Gov. Code § 844; AR-077-S05). Pretrial detainees are therefore "prisoners" for these sections even though they are not "prisoners" for constitutional purposes (Roadmap 041). (Grade: Settled as to text.)

The general immunity (Gov. Code § 844.6). Except as provided in listed sections — including §§ 814, 814.2, 845.4 and 845.6 — and in the Penal Code's provisions beginning at § 3500, a public entity is not liable for an injury proximately caused by any prisoner or for "An injury to any prisoner" (§ 844.6(a); AR-051-S02). But "Nothing in this section exonerates a public employee from liability for injury proximately caused by his negligent or wrongful act or omission" (§ 844.6(d)). The entity may, but is not required to, pay a judgment or indemnify an employee where the entity is immune under the section, "except that the public entity shall pay, as provided in Article 4 (commencing with Section 825) of Chapter 1 of this part, any judgment based on a claim against a public employee who is lawfully engaged in the practice of one of the healing arts under any law of this state for malpractice arising from an act or omission in the scope of his employment," and any compromise or settlement of such a malpractice claim to which it has agreed (§ 844.6(d)). (Grade: Settled as to text.)

The structure is asymmetric, and the asymmetry is the key to custody malpractice against public employees. The public entity is immune from direct liability for injuries to prisoners; its employees are not immune for their own negligence; and for one class of employees — those lawfully practicing a healing art — the entity must pay the malpractice judgment. Watson v. State of California (1993) 21 Cal.App.4th 836 states the consequence: "Section 845.6 requires that the medical malpractice action be brought against the employees, not the public entity" (p. 842), and, quoting Flores v. Natividad Medical Center, "Although the State is required to pay the judgment assessed against its employees for medical malpractice committed against a prisoner, the State is immune from suit directly" (p. 842) (AR-051-C01). (Grade: Majority/likely — Court of Appeal authority consistently applied.) A public employee's right to a defense and the entity's duty to pay judgments generally are governed by Gov. Code § 825: where the employee timely requests a defense in writing "not less than 10 days before the day of trial" and "reasonably cooperates in good faith in the defense of the claim or action," "the public entity shall pay any judgment based thereon or any compromise or settlement of the claim or action to which the public entity has agreed" (§ 825(a), in part; AR-066-S01). (Grade: Settled as to text; the section's further conditions and exceptions were not read in full.)

The duty to summon (Gov. Code § 845.6). "Neither a public entity nor a public employee is liable for injury proximately caused by the failure of the employee to furnish or obtain medical care for a prisoner in his custody; but, except as otherwise provided by Sections 855.8 and 856, a public employee, and the public entity where the employee is acting within the scope of his employment, is liable if the employee knows or has reason to know that the prisoner is in need of immediate medical care and he fails to take reasonable action to summon such medical care. Nothing in this section exonerates a public employee who is lawfully engaged in the practice of one of the healing arts under any law of this state from liability for injury proximately caused by malpractice or exonerates the public entity from its obligation to pay any judgment, compromise, or settlement that it is required to pay under subdivision (d) of Section 844.6" (AR-051-S01). (Grade: Settled as to text.)

The courts have kept the summoning duty and the malpractice claim apart. "Liability under section 845.6 is limited to serious and obvious medical conditions requiring immediate care" (Watson, p. 841), and, describing an earlier Court of Appeal holding, the opinion states that "the failure to summon medical care is not the same as the failure to provide adequate care" (p. 845). In Castaneda v. Department of Corrections & Rehabilitation (2013) 212 Cal.App.4th 1051 (No. B229246, opinion on rehearing filed Jan. 15, 2013, superseding the opinion filed July 26, 2012; reporter citation not displayed on the host; AR-054-C01), the Court of Appeal held the State immune where staff had summoned care and the later failures concerned the quality of the treatment: the statute creates a limited cause of action for the "failure to summon immediate medical care only," "The statute does not create liability of the public entity for malpractice," and "a violation of section 845.6 and medical malpractice are different causes of action" (AR-054-C01). (Grade: Majority/likely.) In the hypothetical, the housing officer's response to a man who was "confused" and "not making sense" is a § 845.6 question — whether the officer knew or had reason to know of a need for immediate care and failed to take reasonable action to summon it — and not a malpractice question. The nurse's response at sick call is a malpractice question.

Mental illness and addiction (Gov. Code § 855.8). The § 845.6 exception is itself subject to § 855.8, which provides that neither a public entity nor an employee acting within the scope of employment "is liable for injury resulting from diagnosing or failing to diagnose that a person is afflicted with mental illness or addiction or from failing to prescribe for mental illness or addiction," and that an employee "is not liable for administering with due care the treatment prescribed," but "Nothing in this section exonerates a public employee who has undertaken to prescribe for mental illness or addiction from liability for injury proximately caused by his negligence or by his wrongful act in so prescribing," or from liability for negligence "in administering any treatment prescribed for mental illness or addiction" (AR-051-S03). (Grade: Settled as to text.) Mental-health, withdrawal and addiction-treatment cases (Roadmaps 060, 061, 062, 063) must therefore be analyzed under § 855.8 as well as §§ 844.6 and 845.6; the scope of § 856 (not opened) is a counsel question.

Vicarious liability and employee liability generally. Outside the prisoner immunities, "A public entity is liable for injury proximately caused by an act or omission of an employee of the public entity within the scope of his employment if the act or omission would, apart from this section, have given rise to a cause of action against that employee," but, "Except as otherwise provided by statute, a public entity is not liable for an injury resulting from an act or omission of an employee of the public entity where the employee is immune from liability" (Gov. Code § 815.2; AR-051-S05). "Except as otherwise provided by statute (including Section 820.2), a public employee is liable for injury caused by his act or omission to the same extent as a private person," subject to "any defenses that would be available to the public employee if he were a private person" (Gov. Code § 820; AR-051-S06). In prisoner-injury cases § 844.6 is the "statute" that displaces § 815.2's entity liability, subject to its listed exceptions. (Grade: Settled as to text; Analytical inference as to the interaction.)

Claims against public employees follow the claim against the entity. "Except as provided in Section 950.4, a cause of action against a public employee or former public employee for injury resulting from an act or omission in the scope of his employment as a public employee is barred if an action against the employing public entity for such injury is barred" under the claim-presentation and suit-timing provisions of the Act; "This section is applicable even though the public entity is immune from liability for the injury" (Gov. Code § 950.2; AR-051-S07). (Grade: Settled as to text.) A malpractice claim against a county-employed physician therefore requires a timely Government Claims Act claim against the county even though the county itself is immune from direct suit under § 844.6 (Roadmaps 078, 079, 131; Gov. Code §§ 911.2, 945.4, 945.6, AR-096-S01–S03). Section 950.4, examined in a 2025 statutory reproduction, provides a narrow exception if the plaintiff pleads and proves that within the claims-presentation period the plaintiff did not know and had no reason to know the injury was caused by an act or omission of the public entity or its public employee acting within employment. The exception is not a general waiver of late claims; pleading and proof remain case-specific.

Contractor clinicians and public employees

For the Claims Act, "“Employee” includes an officer, judicial officer as defined in Section 327 of the Elections Code, employee, or servant, whether or not compensated, but does not include an independent contractor" (Gov. Code § 810.2; AR-078-S02; R1 AR-S506). (Grade: Settled as to text.) A private contractor’s employee is not automatically a county employee merely because the contractor delivers county jail care; Gov. Code § 810.2 excludes an independent contractor from its definition of public employee. But an individual’s actual public-employee status must be assessed from the employment and agency arrangements, not merely the name of the payor, and the private contractor is not converted into a public entity by its contract (Model 131). Several consequences follow, each graded as an inference that counsel must confirm on the facts and the contract:

• The Government Claims Act's claim-presentation requirement, which applies to claims against public entities and (through § 950.2) to claims against public employees, does not on its face apply to a malpractice claim against a private contractor or its employees. (Grade: Analytical inference; no appellate authority on the point was opened for this page.) The ordinary MICRA rules — § 364 notice and § 340.5 — govern those defendants.
• Section 844.6(d)'s requirement that the public entity pay malpractice judgments against its healing-arts employees does not on its face extend to the employees of an independent contractor. Who pays a judgment against a contractor clinician is a question of the contractor's own liability, its insurance and the county contract's indemnity terms (Roadmap 086). (Grade: Analytical inference.)
• The text of §§ 844.6 and 845.6 expressly addresses public entities and public employees; a private contractor cannot establish that status simply by performing a governmental contract. Possible immunity by derivative or other doctrine, if advanced, requires a separate pleaded statutory or decisional basis. No controlling California appellate authority establishing a broad private-vendor extension was verified here; that is a research gap, not affirmative evidence of a split. (Grade: statutory scope verified in reproduction; other immunity theories unresolved.)
• A physician who contracts directly with a county as an independent contractor is in the contractor's position, not the employee's; a physician whom the county employs is a public employee; and a county may use both models in the same facility. (Grade: Analytical inference.) The question for every individual clinician is which entity employed or engaged them, which is answered from the county contract, the employment and credentialing records and the entity's own filings (Worksheet 101; Roadmaps 003, 004, 094).

The same distinction matters for the federal claim in a different way: a private clinician providing care to prisoners under contract acts under color of state law for § 1983 purposes, and the private entity's liability under § 1983 requires its own policy or custom (Roadmaps 045–047). Those federal rules do not change the state-law classification above.

Vicarious and institutional liability of the clinician's employer

A private employer's liability for its employees' malpractice ordinarily rests on respondeat superior: "an employer is vicariously liable for the torts of its employees committed within the scope of the employment" (Lisa M. v. Henry Mayo Newhall Memorial Hospital (1995) 12 Cal.4th 291, 296; AR-066-C04; R1 AR-C24). The test asks whether the tort was engendered by or arose from the work — "the incident leading to injury must be an "outgrowth" of the employment" (p. 298) — and whether the risk was "a generally foreseeable consequence of the activity" (p. 299, quoting Rodgers v. Kemper Constr. Co.). (Grade: Settled.) A clinician's negligent care of a patient in the course of assigned clinical duties is the paradigm of conduct within the scope of employment. (Grade: Analytical inference.) Whether a contractor is vicariously liable for a clinician it engaged as an independent contractor, or for a clinician employed by an affiliated professional corporation, depends on agency, ostensible-agency and nondelegable-duty doctrines that this page does not address (Roadmaps 003, 086). Direct institutional negligence — inadequate protocols, staffing or supervision — is a separate theory; CACI No. 514 states it for hospitals (AR-066-G07), and its application to correctional providers is a counsel question.

Peer review and quality records: Evidence Code § 1157 precision

Malpractice cases generate post-event review: a morbidity-and-mortality conference, a quality-improvement review, a root-cause analysis, a medical-staff committee's evaluation of a clinician. Evidence Code § 1157 provides that "Neither the proceedings nor the records of organized committees of medical, medical-dental, podiatric," and other listed professional staffs, "or of a peer review body, as defined in Section 805 of the Business and Professions Code, having the responsibility of evaluation and improvement of the quality of care rendered in the hospital, or for that peer review body," and of listed society review committees, "shall be subject to discovery" (§ 1157(a); AR-032-S04). An attendee at such a meeting "shall not be required to testify as to what transpired at that meeting" (§ 1157(b)). The protections do not apply to statements by an attendee who is a party to an action whose subject matter was reviewed at the meeting, to a person requesting hospital staff privileges, or in a bad-faith action against an insurer (§ 1157(c)), and they do not apply to listed professional-society committees "that exceed 10 percent of the membership of the society, nor to any of those committees" "if a person serves upon the committee when his or her own conduct or practice is being reviewed" (§ 1157(d)). (Grade: Settled as to text.)

The precision rule for this series is that § 1157 protects the proceedings and records of qualifying committees from discovery; it does not protect the underlying facts, the medical record, or documents created in the ordinary course of care, and it does not automatically reach every document labeled "quality" or "peer review." Whether a jail health program's review body is an organized medical-staff committee or a § 805 peer review body (Bus. & Prof. Code § 805, AR-023-S07) with the statutory responsibility is a fact question that the party asserting the protection must establish. (Grade: Analytical inference; counsel question.) No reader should attempt to obtain any review record outside discovery (records key X). Roadmaps 064, 073 and 085 address mortality reviews, internal quality review and peer-review protections in detail.

The constitutional claim is separate

The same record may support a federal claim. For a pretrial detainee in the Ninth Circuit, the Fourteenth Amendment medical-care claim is judged by an objective standard that requires more than negligence but less than subjective intent — something akin to reckless disregard, as the register entry records the holding (Gordon v. County of Orange, 888 F.3d 1118 (9th Cir. 2018), AR-0961-C01); for a convicted prisoner, the Eighth Amendment requires subjective knowledge and disregard of an excessive risk (Farmer v. Brennan, AR-0961-C03), and malpractice does not become a constitutional violation because the patient is a prisoner (Estelle v. Gamble, AR-0961-C02). (Grade: Settled.) The Government Claims Act's presentation requirement does not apply to a § 1983 action (Williams v. Horvath (1976) 16 Cal.3d 834, R1 AR-C08). (Grade: Settled.) Section 364 by its terms reaches actions "based upon the health care provider's professional negligence," and the MICRA damages limits are written for professional-negligence actions; whether any MICRA provision affects a § 1983 claim is addressed in Roadmap 044 and is, in the series' view, answered by the federal character of the claim. (Grade: Analytical inference.) The state claims, if joined in federal court under supplemental jurisdiction (28 U.S.C. § 1367, AR-0961-F03), keep their state prerequisites.

Who is a health-care provider in a custody setting#

The MICRA statutes apply to "health care providers," and a custody case usually involves several kinds of actor. It helps to sort them before any notice is drafted.

Individual licensed clinicians — physicians and surgeons, psychiatrists, nurse practitioners, physician assistants, registered nurses, licensed vocational nurses, psychologists, dentists and pharmacists — are persons "licensed or certified pursuant to Division 2 (commencing with Section 500) of the Business and Professions Code" and are health-care providers under every MICRA definition (AR-069-S06). (Grade: Settled as to text.) Each is measured against practitioners of the same kind (CACI Nos. 501, 502, 504).

Licensed facilities — a correctional treatment center (Health & Saf. Code § 1250(j), AR-073-S06), an outside general acute care hospital, a licensed clinic — are health-care providers under the "health facility" and "clinic" language, and under § 3333.2 a facility licensed under chapter 2 is a "health care institution." (Grade: Settled as to text.) An unlicensed jail clinic area is not, on that ground alone, a licensed facility. (Grade: Analytical inference.)

Employers and practice organizations — a county that employs clinicians, a private contractor, a medical group or professional corporation — are within § 3333.2's definition of "health care provider" as the provider's "employer, professional corporation, partnership, or other form of legally recognized professional practice organization." (Grade: Settled as to § 3333.2 text.) Their status under §§ 340.5, 364, 3333.1 and 667.7 is the counsel question flagged above. (Grade: Analytical inference; counsel question.)

Custody personnel — deputies, correctional officers, classification and transport staff — are not health-care providers. Their failures to act on obvious medical emergencies are analyzed under § 845.6 (and, for the federal claim, the constitutional standards), not under MICRA. (Grade: Settled as to text; Analytical inference as to application.)

Telehealth and off-site specialists who see custody patients remotely or by referral are licensed health-care providers and may be unaffiliated with the jail providers for § 3333.2 purposes, depending on their contracts. (Grade: Analytical inference.)

Sequencing the notice, the claim and the complaint#

In a custody malpractice case with mixed defendants, three instruments may be required, and they serve different functions. They are described here only as sources and functions; their timing is for counsel.

The notice of intent under Code Civ. Proc. § 364 goes to each health-care provider against whom a professional-negligence action will be brought, at least ninety days before the action is commenced, stating "the legal basis of the claim and the type of loss sustained, including with specificity the nature of the injuries suffered" (AR-096-S04). It is required whether the provider is a private clinician, a contractor, or a public-employee clinician. Its service within the last ninety days of the § 340.5 one-year period tolls that period for ninety days (Woods, AR-066-C02).

The government claim under Gov. Code §§ 910 and 911.2 goes to the public entity — the county or the state — for any claim against the entity or against its employees in the scope of employment, including a malpractice claim against a public-employee clinician (§ 950.2, AR-051-S07; AR-131-S01; AR-096-S01). Its rejection status must be read alongside the actual § 913 notice and service evidence, not just the fact that an agency acted or 45 days elapsed. Gov. Code § 945.6(a)(1) provides a six-month suit period measured from § 913-compliant notice personally delivered or deposited in the mail; without such notice, § 945.6(a)(2) supplies a two-year-from-accrual period, subject to statutory exceptions and any qualifying § 912.4(b) extension. Andrews v. Metropolitan Transit System (2022) 74 Cal.App.5th 597 held that a rejection letter missing the mandatory attorney-consultation warning did not trigger the six-month period. A late-issued but compliant rejection letter is different from a defective one. Gov. Code § 945.6(b) includes a narrow state-prison sentence/civil-rights exception; it is not routine prison tolling, and § 352.1(b) separately excludes claim-required actions. (AR-096-S03; S07; S10.) A notice of intent served on a public entity may be treated as a defective claim that triggers the entity's duty to give notice of insufficiency (Phillips, AR-078-C03), but a claimant should not rely on that.

The complaint must plead each claim against each defendant with the facts that support it, and must be filed within the applicable period for each defendant. Do not allege a fact without a good-faith factual basis. A qualified expert’s review should be obtained as early as practicable; however, the complete record may be unavailable before statutory notice or government-claim deadlines. Counsel must determine what can truthfully be presented or filed to preserve rights while arranging expert review, rather than allowing a records or expert delay to expire a separate deadline (Roadmap 074; Model 129.1). A private contractor and its employees, a public-employee clinician, the public entity and custody officers may be governed by different periods and different prerequisites even though they were all present in the same night's events (Roadmaps 008, 078, 082).

Applying the law to the hypothetical#

The man's potential state-law claims sort into three groups, each analyzed differently. Nothing in this section states what the records would show or what any expert would conclude.

The nurse's assessment and the failure to contact the on-call provider. The licensed vocational nurse is a licensed health-care provider, and her assessment, her use of a protocol medication and her decision not to contact the provider were acts in the rendering of professional services. A claim against her is professional negligence (Flowers; § 340.5 definition). The standard is that of reasonably careful licensed vocational nurses in similar circumstances (CACI No. 504), and the duty-to-consult theory recognized in the CACI No. 508 Sources (Fraijo) frames the central question: would a reasonably careful nurse, presented with that blood pressure and those symptoms, have contacted the provider? The facility's written nursing protocol is evidence of what the institution expected (Title 15 requires that care by non-physician personnel be performed under written protocol or order, AR-031-R03), but the protocol is not itself the legal standard; experts supply the standard (Roadmaps 074, 088). An expert would also have to address causation: whether a timely provider contact would, to a reasonable medical probability, have led to treatment that prevented or reduced the stroke (Civ. Code § 1714.8; Roadmap 075).

The on-call provider and the medication gap. If records show that the provider was in fact contacted, or that the provider had earlier responsibility for continuing the man's antihypertensive medication after booking, the provider's own decisions would be analyzed under CACI No. 501 or No. 502 for the provider's kind. Whether a medication-continuity failure was a clinician's error, a pharmacy or verification process failure, or a policy is a question for the records (Roadmap 056); the answer determines whether the theory is individual malpractice, institutional negligence, or a § 1983 policy claim.

The housing officer. The officer is not a health-care provider. The question is whether the officer knew or had reason to know that the man was "in need of immediate medical care" and failed "to take reasonable action to summon such medical care" (§ 845.6). The courts limit that duty to "serious and obvious medical conditions requiring immediate care" (Watson). Confusion and incoherent speech in a man known to the facility as hypertensive and recently seen for headache and blurred vision present a fact question under that standard. A § 845.6 claim against a county officer and the county requires a timely government claim (§§ 911.2, 945.4).

The employers and the county. If the nurse was employed by the private contractor, the contractor's liability for her negligence would rest on respondeat superior (Lisa M.), and the Government Claims Act would not, on the face of § 810.2, govern the claim against her or the contractor. If she was a county employee, the county would be immune from direct suit for the injury to a prisoner (§ 844.6(a)), she would remain liable for her own malpractice (§ 844.6(d)), the county would be required to pay a malpractice judgment against her (§ 844.6(d); Watson), and a timely claim against the county would be a precondition to suing her (§ 950.2). Which of those configurations applies is the first thing counsel would establish (Worksheet 101).

MICRA. For defendants and professional services that actually meet each relevant statute’s definitions: a § 364 notice at least ninety days before suit (subject to the fictitious-name exception and § 365’s consequence rule); the § 340.5 period (with the pretrial-detention tolling question unsettled under § 352.1 and inapplicable to claim-required public-entity and public-employee claims); the § 3333.2 limit on noneconomic damages in the non-death provider category in effect at judgment, award or settlement, with any outside hospital considered for a distinct cap only if affiliation and independent-negligence criteria can be established; economic damages for the cost of lifelong care and lost earnings without statutory limit, subject to § 667.7 periodic payment at either party's request; the § 3333.1 collateral-source election; the § 6146 fee limits; and § 425.13's leave requirement for any punitive-damages claim.

The federal claim. Because the man was a pretrial detainee, a Fourteenth Amendment claim would be judged under Gordon's objective standard, which requires more than negligence (Roadmap 042). Whether the nurse's or officer's conduct meets that standard is a separate question that this page does not reach (Roadmap 044).

Bankruptcy/entity gate. A name associated with Wellpath is not enough to establish that a particular legal entity is a Chapter 11 debtor, protected nondebtor, or subject to a currently operative stay, discharge, injunction or release. Counsel must obtain the primary petition, debtor schedule, confirmed-plan orders, amendments and entity-specific operative orders from the original bankruptcy docket before any litigation or collection step. The separate Roadmaps 090/091 mapping remains on numbering hold and cannot substitute for primary docket inspection.

A step-by-step approach#

1. Fix the chronology. Build a dated chronology from what the patient lawfully has and what can be requested: symptoms, requests, assessments, vital signs, orders, medication administration, custody observations, transfer, diagnosis (Worksheet 100; Roadmap 006).
2. Obtain the patient's own records by statutory request. Request the custody health record and the outside hospital record under Health & Saf. Code § 123110 (AR-057-S09); for a deceased patient, through the personal representative (Roadmap 065). Do not attempt to access any jail, contractor or hospital system.
3. Identify every actor by role and license. For each person in the chronology: licensed health-care provider or custody staff; which license; which entity employed or engaged them (Worksheet 101; Roadmaps 003, 094).
4. Classify each act. Professional negligence in the rendering of professional services; § 845.6 failure to summon; ordinary negligence; possible constitutional claim. Record the classification and its uncertainty.
5. Run parallel expert and deadline tracks. Obtain a qualified clinical assessment promptly (Roadmap 074), but do not postpone time-sensitive Government Claims Act presentation or a § 364 notice while awaiting a complete chart or final expert opinion. Counsel determines the minimum truthful content, service requirements, and protective sequencing for each instrument; qualified expert support remains central to proving breach and causation.
6. Map the prerequisites. For each defendant: § 364 notice (health-care providers); Government Claims Act claim (public entity; public employees through § 950.2); PLRA exhaustion for any federal prison-conditions claim (Roadmap 080).
7. Map the period sources without computing them. For each defendant and each claim: § 340.5, § 335.1, §§ 911.2 and 945.6, § 352.1's possible application and limits, § 364(d) (Roadmaps 008, 082). Counsel computes.
8. Send preservation demands for the EHR audit trail, unit logs, protocols, call logs, staffing records and video (Roadmap 007; Model 132).
9. Serve the notices and present the claims in the sequence counsel determines; draft the complaint. Do not allege a fact unless you have a good-faith factual basis for it.
10. Check the bankruptcy gate. Check Roadmaps 090/091 before suing any Wellpath debtor entity.

Elements of the claim#

Professional negligence (against each health-care provider defendant). (1) The defendant was a health-care provider who undertook the care of the patient, creating a duty; (2) the defendant failed to use the level of skill, knowledge and care that reasonably careful practitioners of the defendant's kind would use in the same or similar circumstances (CACI Nos. 501, 502, 504), ordinarily proven by expert testimony; (3) the failure was a substantial factor in causing harm (CACI No. 400), ordinarily proven to a reasonable medical probability by expert testimony; (4) damages. Statutory conditions: § 364 notice; § 340.5 period; § 3333.2 limits on noneconomic damages. (Grade: Settled.)

Vicarious liability of the employer. The clinician's negligence; employment (or agency) at the time; conduct within the scope of employment (Lisa M.). (Grade: Settled.)

Failure to summon (Gov. Code § 845.6), against a public employee and the public entity. (1) The patient was a prisoner (§ 844); (2) the employee knew or had reason to know that the patient needed immediate medical care for a serious and obvious condition; (3) the employee failed to take reasonable action to summon care; (4) causation; (5) damages. Government Claims Act prerequisites apply. (Grade: Settled as to text; Majority/likely as to the "serious and obvious" limit.)

Malpractice against a public-employee clinician. The professional-negligence elements, plus a timely government claim against the employing entity (§ 950.2); the entity pays a resulting judgment (§ 844.6(d)). (Grade: Settled as to text.)

Roadmap 096.3 sets out the element tables in comparative form, and Model 129.1 shows how they are pleaded.

Potentially relevant defendants#

By role and function only; no entity is identified here as liable.

• Individual licensed clinicians who assessed, ordered, administered, triaged or failed to refer — each for that clinician's own care, measured against that clinician's own kind of practitioner.
• The clinicians' employer or engaging entity — a county, a private correctional-health contractor, a medical group or professional corporation — on respondeat superior or agency theories, and on any direct institutional theory the facts support. The employing entity must be identified from records, never from branding.
• The public entity that operates the facility — for § 845.6 claims through its custody employees, and as the payer of malpractice judgments against its healing-arts employees under § 844.6(d); immune from direct suit for prisoner malpractice under § 844.6(a).
• Custody employees who knew or had reason to know of a need for immediate care — under § 845.6, and in their individual capacities under § 1983 where the facts support it.
• Outside providers — hospitals, emergency physicians, specialists and telehealth providers — for their own care, as unaffiliated providers or institutions where the facts and contracts support that classification.
• Doe defendants whose names are unknown when the complaint is filed; § 364's notice requirement does not apply to them while they are fictitiously named (§ 364(e)), and their later substitution has its own rules (counsel question).

Administrative prerequisites#

• Code Civ. Proc. § 364 notice of intent to every health-care-provider defendant at least ninety days before the action is commenced (AR-096-S04). Failure does not invalidate the proceeding (§ 365, AR-066-S07) but is a statutory breach with consequences for counsel.
• Government Claims Act claim to the public entity for claims against the entity or against its employees in the scope of employment, including malpractice claims against public-employee clinicians (Gov. Code §§ 910, 911.2, 945.4, 950.2; AR-131-S01, AR-096-S01, AR-096-S02, AR-051-S07; Roadmaps 078, 079; Model 131). Late-claim relief is limited (§ 911.4, R1 AR-S503).
• No Claims Act claim appears to be required, on the face of § 810.2, for a claim solely against a private contractor or its employees (Analytical inference); counsel confirms the employment facts and the contract first.
• PLRA exhaustion applies to federal prison-conditions claims brought by a person who is a prisoner when suit is filed (42 U.S.C. § 1997e, AR-096-F04; Roadmap 080); it is a federal-claim prerequisite, not a condition of the state malpractice claim.
• Expert review before filing. A competent early clinical review is a strong prudential step (Roadmap 074), not an independently demonstrated universal California statutory precondition to every notice, government claim, or complaint. Counsel must distinguish any case-specific certification or expert-declaration requirement from the ordinary later burden to prove the clinical standard of care and causation; no universal certification statute has been authenticated for this roadmap. (Grade: Analytical inference.)

Evidence and records to obtain#

Key: H presently has lawfully; R statutory request; D discovery or subpoena only; P potentially privileged or private; K someone else must preserve but need not produce voluntarily (Roadmap 007); X must not access, copy or remove.

• The patient's own copies of health-care request forms, grievances and responses, discharge papers and release documents — H.
• The patient's custody health record: sick-call notes, nursing assessments with vital signs, provider orders and telephone orders, progress notes, medication administration records, intake screening, referral and transport records — R (Health & Saf. Code § 123110, AR-057-S09); before suit, a representative presenting the patient's written authorization may inspect and copy provider records under Evid. Code § 1158 (AR-083-S09).
• Outside hospital, ambulance and specialist records — R.
• The county's health-services contract, amendments, staffing exhibits and any public reports on the facility's health program, and any license for a correctional treatment center — R (California Public Records Act, Gov. Code § 7920.000 et seq., R1 AR-S801; Roadmaps 086, 087).
• Written nursing protocols, the on-call schedule, telephone-call logs to the on-call provider, and pharmacy and medication-verification records — D; K pending suit.
• The EHR audit trail showing who created, viewed and amended each entry and when — D; K.
• Housing-unit logs, observation records, intercom and call-button records and video — D; K.
• Employment, credentialing and licensing records of each clinician, and the agreements among the entities that employed or engaged them — D (licensing status is public: Roadmap 092).
• Morbidity, mortality and quality-review records and committee minutes — P (Evid. Code § 1157, AR-032-S04); X outside discovery.
• Other patients' records — P; X.
• Communications with counsel and the consulting expert's work — P.

The rule throughout: nothing is taken from any jail, contractor, hospital or peer-review system. A patient, a family member or a former employee who possesses such records without authorization should tell counsel and do nothing further with them.

Favorable and adverse facts#

Facts that tend to support the claim. A documented vital sign or finding that crosses a threshold the facility's own protocol treats as requiring escalation, with no record of escalation; a gap in a medication that the patient was known to need; repeated requests describing the same worsening symptoms; a custody log describing an obvious emergency; an expert review identifying a specific departure and explaining, to a reasonable medical probability, how timely care would have changed the outcome; an audit trail that shows late entries or amendments after the event.

Facts that tend to undercut it. A documented assessment with a reasoned clinical judgment that an expert would accept as one of the medically accepted approaches (CACI No. 506); a patient who refused assessment or medication, documented with an informed refusal (Roadmap 072); an outcome that the natural course of the disease would have produced even with timely care (Civ. Code § 1714.8; Roadmap 075); a long interval between the event and any request for records or notice; an expert who will not support breach or causation; the absence of any public-employee status where the claim strategy depended on § 844.6(d).

Facts that cut both ways. Protocol compliance, which may show reasonable care or may show a protocol that itself fell below the standard; custody constraints on movement, which the defense will present as circumstances and the plaintiff may present as known risks that required planning.

Likely defenses#

Roadmap 133 states the defense positions in full; the most likely here are:

• Standard of care met. Expert testimony that the care was within the standard, including the alternative-methods instruction (CACI No. 506; Roadmap 133, "No breach; standard of care met").
• No causation. Expert testimony that the outcome would have been the same; Civ. Code § 1714.8 (Roadmap 133, "No causation (medical)").
• Expert failure. No qualified expert, an expert of the wrong kind, an unsupported opinion, or late disclosure (Roadmap 133, "Expert failure"; Roadmap 074).
• Limitations. Section 340.5's one-year discovery period; the three-year outer limit; the inapplicability of § 352.1 to the three-year period and to claim-required public claims; the Claims Act periods (Roadmap 133, "Limitations").
• Claims Act bar and immunities. No timely claim; § 844.6(a) for the entity; the narrow scope of § 845.6; § 855.8 for mental-illness and addiction diagnosis (Roadmap 133, "Government Claims Act bar").
• Classification. That the claim is or is not professional negligence, depending on which side the classification favors in the case (Flowers).
• MICRA limits. Section 3333.2's category limits; § 3333.1; § 667.7 (Roadmap 133, "MICRA limits; survival limits").
• Peer-review protection for review records (§ 1157; Roadmap 133, "Peer-review privilege").
• Bankruptcy discharge, injunction or plan release as to a debtor entity (Roadmaps 090, 091).

The deep companions to Roadmap 133 for these defenses are Playbooks 143 (expert gatekeeping and procedure), 138 (causation, damages and MICRA) and 135 (claim presentation and § 364).

Causation#

Causation in a custody malpractice case is ordinarily the hardest element and the one most often decided by experts. The plaintiff must show that the breach was a substantial factor in causing the harm (CACI No. 400), and the courts require that a medical causal link be shown to a reasonable medical probability on competent expert testimony (CACI No. 500 Sources, quoting Belfiore-Braman; description level). Delay cases turn on the counterfactual — what would have happened with timely care — and on the natural history of the condition, which Civ. Code § 1714.8 removes as a sole basis for liability while preserving liability for negligent diagnosis and treatment (AR-066-S05). Multiple actors raise the question of whose breach caused which part of the harm, which matters for the category structure of § 3333.2 and for apportionment among defendants (Roadmap 076). Roadmap 075 addresses causation doctrine in detail, including the lost-chance problem and the distinct causation questions in § 845.6 and § 1983 claims.

Damages and remedies#

Economic damages — past and future medical care, rehabilitation and attendant care, and lost earnings and earning capacity — are recoverable on proof and are not limited by § 3333.2. Noneconomic damages against health-care providers are limited by category under § 3333.2 at the amount in effect at the time of judgment, arbitration award or settlement. Future damages of $250,000 or more may be ordered paid periodically at either party's request (§ 667.7). The defendant may elect to introduce collateral-source benefits (§ 3333.1). Punitive damages require leave under § 425.13 and cannot be recovered from a public entity. Counsel's fee is limited by § 6146. Against a public-employee clinician, the public entity pays the malpractice judgment (§ 844.6(d)). Survival and wrongful-death damages, including the separate wrongful-death limits in § 3333.2(c), are addressed in Roadmap 065, and the full remedies picture in Roadmaps 076 and 096.2 ("Malpractice damages and MICRA"). Federal § 1983 damages and attorney's fees follow federal rules (Roadmap 044).

Discovery#

Discovery in a custody malpractice case centers on the complete medical record with its audit trail, the protocols and call logs that show what the institution expected and what happened, the custody logs and video that show what non-medical staff saw, the employment and contract records that identify each actor's employer, and the depositions of the clinicians and the entity's designee. Expert disclosure follows Code Civ. Proc. § 2034.210 et seq. in state court and Fed. R. Civ. P. 26(a)(2) in federal court (Roadmap 074). Peer-review and quality-committee records are subject to § 1157's protections as described above, and the protection's application to a correctional program's review body is contested ground (Roadmap 085). Roadmaps 084 and 038 describe discovery tools, protective orders and privilege practice; Roadmap 083 covers the patient's own records and the Confidentiality of Medical Information Act.

CFMG/Wellpath-specific relevance#

Why this may matter in a CFMG/Wellpath setting. The public record describes California counties contracting with private correctional-health companies to deliver jail health care, so that in a contracted facility the clinicians whose care is questioned may be employees of a private entity or of an affiliated professional corporation rather than public employees (Roadmaps 003, 004). That structure determines which rules on this page apply: whether the Government Claims Act governs a claim against a clinician (§§ 810.2, 950.2), whether the county must pay a malpractice judgment (§ 844.6(d)), whether the prisoner immunities can be invoked, and how § 3333.2's affiliated and unaffiliated categories are drawn — each of which is answered from the county contract and its amendments, which are public records subject to the Public Records Act's exemptions (Roadmaps 086, 087), and from employment and entity records (Worksheet 101). Entity precision is mandatory. The inherited R1 register asserts that California Forensic Medical Group, Inc. is omitted from a debtor notice and that Wellpath CFMG, Inc. appears under Case No. 24-90556 in a jointly administered chapter 11 docket; these details have not been authenticated in this revision against the complete primary petition, amendments, debtor lists and operative plan or stay orders. An omitted name on one list is not affirmative proof that an entity is outside all relevant orders; similarly, a name appearing in an inherited citation cannot establish current relief. Treat this as an unverified documentary lead, not an established finding about any party. Counsel must review original bankruptcy dockets and distinguish exact state-law entities before action; the 090–091 namespace remains held. Liability is never inferred from branding on a uniform, a form or a medication cup. Nothing here states that any entity or clinician breached any standard of care, failed to summon care, or is liable to any person.

Companion worksheet#

Worksheet 109 (custody, medical, medication, referral, grievance and emergency records) organizes the record; Worksheet 101 (entity identity) answers, for each clinician, the employer question on which the Claims Act and § 844.6(d) analysis turns; Worksheet 100 (chronology) fixes the dated sequence an expert will review; Worksheet 112 (damages and mitigation) organizes economic losses that MICRA does not limit; Worksheet 114 (preservation and records distinction) applies the H/R/D/P/K/X key. The dedicated companions are Worksheet 120 (Claim, Notice and Limitation-Source Tracker — sources and documents only, no computed dates), which can carry a malpractice-prerequisites sheet listing, for each defendant, license type, employer, public or private status, § 364 notice status, Claims Act status and the period sources that counsel has confirmed, and Worksheet 119 (Clinical-Course and Causation Timeline Worksheet), for the clinical course an expert will review.

What this page cannot do#

It cannot tell any reader whether care met the standard of care, whether a claim exists, whether a notice or claim is required for a particular defendant, or when any period began or ends. It cannot classify any clinician's employment, resolve the unsettled questions it flags — pretrial-detention tolling, the status of unlicensed employers under §§ 340.5 and 364, the availability of the prisoner immunities to private contractors, the application of § 1157 to a correctional review body — or substitute for a qualified expert's review and a lawyer's judgment. It explains the structure of the claim so that the record can be built for the experts and counsel who must apply it.
