This page explains how KPSGILL.com’s investigation of healthcare enforcement was researched, how its evidence labels work, what it does and does not publish, and how it will be corrected. It is part of the investigation, not an appendix to it.
The standard
The investigation is built to survive a reader who wants it to be wrong. Before publication, every passage about unresolved conduct was tested against five questions:
- What source supports this statement?
- Is it a fact, an allegation, a settlement contention, a court finding, an admission, a charge, an inference, or a private-source assertion?
- Has liability actually been adjudicated?
- Does the sentence transfer liability from one entity to another?
- Could the sentence reasonably be read to say that someone committed a crime when the record only alleges it?
Where the answer to the last two was yes, the sentence was rewritten. The draft was then reviewed from four positions — defense counsel, prosecutor, judge and investigative editor — and against one final question: could a defense attorney, prosecutor, judge, investigative reporter, compliance officer, physician and ordinary reader all distinguish what is known from what is alleged?
Evidence labels
What a court, agency or statute says, checked against the original document.
How a matter ended: settlement, plea, judgment, or agreement. Read the label: most settlements carry no finding of liability.
What a party alleges or contends, including criminal charges and pending civil claims. Not proof.
Contemporaneous correspondence held privately. It shows what was asked or asserted at the time, not what was proved.
KPSGILL.com's reasoning from the record, or a question the record leaves open.
Labels attach to the passage that follows them. A passage can carry more than one — a settlement that also includes a corporate integrity agreement, or a private record whose meaning remains unresolved. The labels are a reading aid and an editorial safeguard; they do not change what the sources say.
Source priority
When sources conflict, the higher source controls:
- The current PACER docket (generated October 25, 2026, 3:30 p.m. Pacific, through docket entry 101)
- The executed federal settlement agreement
- Federal court orders
- DOJ and U.S. Attorney releases
- HHS-OIG records and the corporate integrity agreement
- Statutes and regulations
- Published judicial opinions
- Original historical documents in the private archive
- Contemporaneous email correspondence
- Earlier KPSGILL.com research
An older secondary account never overrides a newly recovered primary source. Where a public record and a private record differ, the difference is reported, not resolved by assumption.
What each kind of record can prove
- A docket proves that procedural events occurred: filings, orders, hearings.
- A pleading proves what a party alleged.
- A settlement proves its terms, including any admissions or denials. Most healthcare settlements include no determination of liability.
- A charging document proves what prosecutors allege. Defendants are presumed innocent.
- A plea or judgment establishes an adjudicated outcome for the person or entity it binds.
- A private email proves that a communication was sent or received, subject to authentication. It does not prove the truth of its contents.
- A tax return copy proves what that copy reports. Until matched to the filed return, it proves no more.
The national data
The statistical series covers fiscal years 2001 through 2025 from a single DOJ publication vintage. The 25-year totals are KPSGILL.com’s arithmetic, checked row by row against the source. Annual settlement totals, case amounts, submitted claims, paid claims, restitution and alleged losses are different categories and are never added together. The case timeline is a representative selection through October 25, 2026, not an inventory of every enforcement action. E22
Names and de-identification
This investigation is de-identified at the level of individuals and verifiable at the level of institutions and dockets.
- Named: organizations, agencies, courts, statutes, case numbers, settlement amounts, dates, regulatory documents and publicly relevant institutional relationships.
- Described by role: private individuals, including physicians, executives, employees, agents, defendants and the relator — for example, “a PNA sales executive,” “an FBI agent,” “two physician defendants.” Some roles are public corporate offices, so a role description can identify its holder; where that is so, the description is used only because the office, not the person, is what the record concerns. A PNA executive described in the 2016 correspondence was among the individual defendants dismissed in June 2025; no inference about that person is drawn from the correspondence.
- Not published: personal email addresses, telephone numbers, mailing addresses, mailbox identifiers, internal archive identifiers, private attachments, litigation-strategy material, communications with counsel and privileged material.
The public litigation is not anonymous. The case caption carries the relator’s surname, and official documents linked from the source ledger identify parties by name. Minimizing names in the narrative is an editorial choice, not an attempt to alter the public record.
The private archive
Some records reviewed for this investigation are held privately: the original seven-page October 8, 2015 letter, preserved unchanged; 27 email messages from 2011 to 2019 reviewed in full; a privately supplied copy of a 2018 Form 990, whose figures are withheld until matched to the IRS-filed return; and an earlier working review of the historical record. These are described and, where useful, quoted briefly. They are not published, and the public investigation is a separate layer from the private archive. The email records are selected service exports, not an exhaustive or forensically certified mailbox collection, and quoted messages can recur within threads, so the message count is not a count of independent assertions.
Disclosure
Responses
This edition does not include new statements from the organizations or individuals involved. Their positions are reported as stated in the settlement agreement and the court record, including CHS’s and PNA’s denials of the settled allegations. KPSGILL.com will publish responses it receives and will note the date of receipt.
What is not yet reviewed
The text of the First Amended Complaint (filed September 15, 2025) has not been reviewed; the investigation therefore does not describe its paragraph-level theories. No written order following the October 19, 2026 discovery conference appears on the docket through the cutoff. The privately supplied 2018 Form 990 copy has not been matched to the IRS-filed return, and its figures are withheld. The original 2010 inquiry and a separately referenced 2015 written response have not been recovered. The historical archive’s coverage of 2021 to 2023 is uneven. These limits are stated where they apply and collected in the evidence-gaps list.
Corrections and updates
Corrections are made in the text and recorded on the page, with the date. Material changes from earlier editions are listed in the investigation’s “What the records corrected” section. Procedural statements are tied to a docket cutoff and will be refreshed when the court rules on the pending motion, issues its written discovery order, or enters any further dispositive order. Readers who find an error can report it to KPSGILL.com; reports are reviewed against the sources, not against the reporter’s identity.
Last verified: October 25, 2026. Docket status as of October 25, 2026, 3:30 p.m. Pacific.
