Why does credentialing take three months?
The 60-second answer
Because the same licence, diploma and training record are verified from scratch by every institution and every payer you encounter, and each verification waits on a third party — usually a medical school or a former employer — that has no deadline.
How the system works
Credentialing is primary-source verification: the institution contacts the issuing body directly rather than accepting your copy. Licence, degree, postgraduate training, board status, malpractice history, references and any adverse actions each go to a different source. The file cannot close until the slowest source replies, and nothing obliges that source to reply quickly.
Who controls the decision
The institution’s medical staff office assembles it; a credentials committee and then the governing board decide. Payer enrolment is a separate process with its own timeline, run by each plan.
Where it fails
Two places. A single unresponsive source stalls the whole file, and nobody in the chain is accountable for the delay. And because no institution relies on another’s verification, a physician who moves has the identical work redone at full length — which is duplication, not scrutiny.
The governing law
Institutional bylaws and accreditation requirements drive the process; adverse actions reach the National Practitioner Data Bank under federal law. Nothing requires reliance on a prior verification performed to a standard.
What physicians experience
Weeks of unpaid limbo, often after a start date has been agreed. A physician can be fully licensed, board-certified and unable to see a patient or bill for one.
What patients experience
A post stays unfilled and appointment availability does not change, for reasons no patient is ever told.
