PECOS web runs about 45 to 60 days typical; paper or applications with information requests run 90 to 180 days
Recredentialing
Revalidation every 5 years with no grace period
National Government Services is the Medicare Administrative Contractor that processes Part A and B enrollment (the 855 series) for Connecticut, Maine, Massachusetts, New Hampshire, New York, Rhode Island, and Vermont (JK) plus Illinois, Minnesota, and Wisconsin (J6). You do not apply to the MAC directly: PECOS auto routes your application to it based on your practice state.
The stall to avoid: PECOS web always beats paper, and a development request unanswered for 30 days is a rejection. Track your revalidation due date: CMS posts it about 7 months ahead.
From PayerReady's payer enrollment research, built from the payer's own provider manuals and enrollment pages. Payer processes change; when a fact is not published by the payer, we say so rather than guess.
