Key takeaways
- Credentialing (verification) and enrollment (billing approval) are related but separate steps.
- Start early — commercial enrollment frequently takes 90 days or more.
- Keep CAQH ProView current and re-attest every 120 days.
- Medicare revalidation is every five years; track every payer’s re-credentialing cycle.
- Don’t schedule a new provider under a payer until the effective date is confirmed in writing.
Credentialing vs. payer enrollment vs. privileging
- Credentialing verifies a provider’s education, training, licensure, board certification, work history, malpractice coverage, and sanctions history.
- Payer enrollment (also called provider enrollment or contracting) is the application to a specific payer to become an enrolled or participating provider so claims can be paid.
- Privileging is a hospital’s or surgery center’s permission to perform specific procedures at that facility. It is separate from payer enrollment.
What do you need before you start credentialing?
| Item | Notes |
|---|---|
| NPI | Type 1 (individual) NPI from NPPES; a group billing entity also needs a Type 2 (organizational) NPI |
| State license(s) | Active license in every state where the provider practices, including states where telehealth patients are located |
| DEA and state controlled-substance registrations | If the provider prescribes controlled substances |
| Board certification | Or documentation of board eligibility |
| Malpractice insurance | Current certificate of insurance and claims history |
| CV and work history | Month/year format, with gaps explained (payers commonly ask about gaps over six months) |
| Tax ID and W-9 | For the billing entity |
| CAQH ProView profile | Complete, documents uploaded, attested, and authorized for each payer |
The payer enrollment process, step by step
- Build and attest the CAQH ProView profile. Many commercial payers pull credentialing data from CAQH. Upload current documents and authorize each payer to view the profile.
- Enroll in Medicare through PECOS and in your state Medicaid program if you will see those patients. Medicaid managed care plans often credential separately even after state enrollment.
- Apply to each commercial payer. Confirm the network is open to your specialty and region first — some panels are closed.
- Link the provider to the group. If claims bill under a group NPI and tax ID, the provider must be linked to the group with each payer — individual enrollment alone is not enough.
- Review and sign contracts. Check fee schedules, timely filing limits, and effective dates before signing.
- Set up ERA and EFT enrollment so payments and remittances arrive electronically.
- Load effective dates into scheduling. Don’t book the provider under a payer until the effective date is confirmed.
How long does provider credentialing take?
Timelines vary widely by payer and state. Commercial enrollment frequently takes 90 days or more from a complete application, and incomplete applications restart the clock. Build the timeline into provider start dates, follow up with each payer on a fixed schedule, and log every submission, reference number, and contact.
How often do providers need to re-credential?
| Requirement | Frequency |
|---|---|
| CAQH ProView re-attestation | Every 120 days |
| Commercial payer re-credentialing | Typically every 3 years (varies by payer) |
| Medicare revalidation | Every 5 years (every 3 years for DMEPOS suppliers) |
| Medicaid revalidation | At least every 5 years (state-specific) |
| License, DEA, malpractice, board certification | At each expiration — update CAQH when renewed |
Common credentialing mistakes that delay revenue
- Letting CAQH attestation lapse, which can stall applications already in process
- Missing a Medicare revalidation notice, which can deactivate billing privileges
- Enrolling the provider individually but never linking them to the group
- Seeing patients before the effective date, then finding the claims cannot be billed retroactively
- Address, taxonomy, or NPI data that does not match across NPPES, CAQH, PECOS, and payer records
