How Primary Source Verification Actually Works

Primary source verification (PSV) means confirming a provider's credential directly with the organization that issued it, rather than trusting a copy the provider supplied. It is the standard that accreditors such as NCQA and The Joint Commission expect, and it is what makes a credentialing decision defensible.

What gets verified at the source

Common primary sources include state medical boards for licensure, the Educational Commission for Foreign Medical Graduates or the issuing school for education, the certifying board for board certification, and the National Practitioner Data Bank for malpractice and sanction history.

Why it is slow

Each source has its own interface, turnaround time, and quirks. Some respond instantly through an online query; others require a mailed request or a phone call. A single provider file can depend on a dozen sources, and the file moves at the speed of the slowest one.

The role of a verified passport

When a provider's credentials have already been verified at the source and stored in a trusted passport, downstream parties can rely on that verification in real time instead of repeating it. That is the shift Bip is built around: verify once, trust everywhere.
