Payer Enrollment
Get on insurance panels and start billing. Enrollment guides for Medicare, Medicaid, and every major commercial payer with state-specific timelines, required documents, and application portals.
What is payer enrollment?
Payer enrollment is the administrative and financial step that links a provider’s NPI and Tax ID to a payer’s claims system, sets an effective billing date, and routes payment via EFT/ERA. It is what answers “can you actually get paid?” — and it is separate from credentialing (verifying you are qualified). A provider can be fully credentialed and still have every claim denied until enrollment is complete and the effective date is set.

Payer enrollment, in depth
Enrollment is the financial handshake that makes a credentialed provider billable. It comes after credentialing and the paneling decision — see how the three steps differ.
Medicare (PECOS)
All Medicare enrollment runs through PECOS. Only providers actively enrolled and approved in PECOS are authorized to submit claims. Effective dates can be retroactive up to 30 days from application receipt in standard cases.
Medicaid (by state)
Each state Medicaid program runs its own enrollment, often through a managed-care layer. Timelines range 30–180 days; reassignment and taxonomy must match the state file exactly.
EFT / ERA setup
Electronic Funds Transfer and Electronic Remittance Advice are separate enrollments — set both up together so payment and remittance arrive through one workflow from day one.
Effective date & the revenue gap
You cannot bill before the effective date. Claims for earlier dates of service are denied with CO-B7 — the biggest preventable loss in the process.
When enrollment timing is wrong, Medicare returns denial CO-B7 — the provider was not eligible for that date of service. The fix is sequencing enrollment correctly and never billing before the confirmed effective date. Want a specialist to manage it end to end? See PayerReady’s credentialing & enrollment services.
