Stage 1 — Entity and identifier foundation
- Legal entity formed, EIN issued, and the legal name matching the IRS letter exactly
- NPI type 2 for the group and NPI type 1 for each rendering provider
- Correct taxonomy codes on every NPI record
- Service locations with billing address, practice address, and hours documented
- Bank account and EFT/ERA enrollment details ready
Errors here propagate into every downstream application. Fixing a taxonomy or legal-name mismatch after five payers have already rejected the file costs weeks.
Stage 2 — Provider document packet
Licenses, DEA and state controlled-substance registrations, board certifications, CV with a gap-free work history, malpractice COI, government photo ID, and any supervision or collaborative practice agreements. Screen every provider against the OIG LEIE and SAM exclusion lists before filing — an excluded provider on a roster is a compliance problem, not just an enrollment one.
Stage 3 — CAQH and payer portals
Build or clean CAQH, authorize the target payers, and attest. Then register in the portals that do not use CAQH: PECOS for Medicare, the state Medicaid portal, Availity, and the payer-specific provider portals. Our CAQH setup guide covers the profile in detail.
Stage 4 — Parallel application filing
File commercial plans, behavioral carve-outs, Medicare, Medicaid, and managed care at the same time. Track each with a submission date, a confirmation or ticket number, a payer contact, and a next-follow-up date. Read commercial insurance credentialing, Medicare enrollment, and Medicaid enrollment by state for the per-channel detail.
Stage 5 — Follow-up cadence
Applications do not progress on their own. A weekly touch on every open file — with escalation to a network representative after two unproductive checks — is what separates a 70-day cycle from a 150-day one. Log every conversation; payer memory is short and yours has to be longer.
Stage 6 — Contracting and rates
Review the fee schedule, effective date, term and termination language, timely-filing window, appeals process, and any all-products clauses. Negotiate before signing, not after the first underpaid claim.
Stage 7 — Roster load, effective date, and go-live
- Get the effective date in writing
- Verify the provider and location appear in the payer's directory
- Confirm the claims system has the record loaded, not just the committee approval
- Complete EFT/ERA setup so payments and remits land correctly
- Load effective dates into the billing system before scheduling against them
Stage 8 — Maintenance
Enrollment decays. CAQH re-attestation every 120 days, license and DEA and malpractice expirables, re-credentialing every 2–3 years, revalidation for Medicare and Medicaid, plus demographic updates whenever a location, name, or ownership detail changes. See the re-credentialing checklist and our compliance monitoring service.

If you would rather not run this internally, that is exactly what our payer enrollment service does — with one named lead per group and weekly status. You can also check realistic dates with the credentialing timeline tracker.
