Where this comes up
Credentialing and revenue-cycle staff handle this — CAQH ProView upkeep, payer-roster validation, NPI maintenance, PECOS revalidation cycles, and the gap between application and effective date that strands new providers. Lapses here block payment until backdated re-enrollment closes the gap.
Full definition
What it is in practice
Credentialing includes verification of education, training, licensure, board certification, malpractice history, and DEA. NCQA and URAC standards set the operational baseline most payers follow.
How it shows up in your practice
Credentialing typically takes 60-120 days. Start the process as soon as the offer letter is signed; backdating is rarely permitted.
