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
CMS generally requires revalidation every 5 years for individuals and every 5 years for institutional providers (3 for DMEPOS). MACs send notices; missing the deadline causes deactivation and claim denials.
How it shows up in your practice
Track revalidation dates centrally and submit 60-90 days before due. Late revalidation is a common revenue interruption.
