CPCS Credentialing and Privileging Complete Practice Test 2026

Primary source verification means confirming credentials directly with the issuing source, such as a licensing board, specialty board, or educational institution. Allowing PSV to be completed by mail, fax, telephone, or electronic means provides the credentialing team with flexible, reliable ways to obtain authoritative information, even when a provider’s primary source portal isn’t available. The AAAHC explicitly recognizes these methods as acceptable for obtaining primary source verification of licensure, board certification, education, and other credentials during credentialing and privileging. This flexible approach helps ensure timely, accurate verification while relying on official sources, which is essential for safe, high-quality ambulatory care.
