Provider credentialing in depth: steps, timelines and renewals
Credentialing verifies a clinician’s qualifications. Payer enrollment is the separate step that contracts the provider with each health plan so claims are paid in network. Delays in either step mean providers cannot bill or are paid at out-of-network rates.
Documents you will need
- State license, DEA registration and any state controlled substance registration
- Board certification, education and training history
- Current malpractice insurance and claims history
- NPI, tax ID and CV with explanations for work history gaps
- Hospital privileges and references where payers require them
Credentialing and enrollment steps
- Complete and attest the CAQH ProView profile, which commercial plans use as a source of provider data.
- Submit applications to each commercial, Medicaid and Medicare payer.
- For Medicare, enroll through PECOS or Form CMS-855I for individual practitioners, with reassignment of benefits to the group on CMS-855R.
- Follow up on each application and record the effective date before scheduling members.
- Set up electronic claims, remittance and payment enrollment with each payer.
Timelines and renewals
Payer timelines vary and commonly run from about two to six months, so applications should start well before a provider’s first day. CAQH profiles must be re-attested every 120 days. Many plans recredential providers about every three years, and Medicare requires revalidation of enrollment about every five years for most providers.
Common reasons for delay
- Incomplete or unattested CAQH profile
- Expired license, DEA or malpractice certificate
- Unexplained gaps in work history
- Mismatched names, addresses or tax IDs between applications
