Provider Credentialing & Payer Enrollment

A new provider who cannot bill for three or four months is payroll without matching revenue. Long timelines usually come from filing applications one after another. Strong credentialing and enrollment starts when the offer is signed — not on the first clinic day — and runs payer tracks in parallel. Every week removed is a week of visits you can bill.

CAQH ProView is where timelines stall

Many experienced clinicians already have a CAQH account from a prior employer. Without attestation in 120 days, the profile expires. Payers pull stale data, reject the packet, and request documents you already hold. Day-one work is update every section, upload current license/DEA/malpractice, and re-attest before any payer application goes out. Skipping CAQH hygiene almost guarantees a restart mid-cycle.

That cleanup can cost 4–6 weeks. We keep attestations current each quarter so re-credentialing does not start from an expired profile again. Malpractice face sheets need the full history most payers require — a current declarations page alone often bounces.

PECOS, Medicaid, and commercials in waves

Medicare PECOS and state Medicaid move slowly. Start them on day one with CAQH. Wave commercials next: BCBS plans early (often the bottleneck), then United, Aetna, Cigna, Humana, then regional networks. Each packet needs tax ID, Type 1 and Type 2 NPIs, W-9, and a cover letter with a named contact. Incomplete packets sit silently. Parallel filing is the difference between ~45-day averages and the 90–120 day industry slog.

• Day 1 documents: state license, DEA, CSR if required, board cert, malpractice face sheet (full history), CV with month/year dates, W-9, education verification, hospital privilege letters, OIG/SAM clearance.
• Day 1 systems: CAQH ProView attestation, PECOS, state Medicaid.
• Days 5–10: commercial applications in complexity waves, not alphabetical order.
• Weekly: live status calls on every open payer — email-only follow-up often runs 90+ days; weekly calls average closer to 35–45.

Hospital privileging should start on day one

Credentialing committees meet monthly or every six weeks. Miss a cycle and you add 30–45 days. If privileges are required, file that application immediately. Group additions, locum-to-perm moves, and panel expansions follow the same pattern: complete file, parallel submissions, documented follow-up until the effective date is written. Waiting on hospital work until commercials finish is a common reason affiliated providers take four-plus months.

Effective dates and backdating requests

Medicare often lands near day 28; Medicaid near day 30; commercials trail by days to two weeks. Ask in writing for a backdated effective date to the application date — it succeeds more often than practices expect on many commercials. Until the letter arrives, do not assume the provider is billable. Silent pending status is how claims go out and return as not-credentialed denials while timely-filing clocks keep running.
