Credentialing & Payer Enrollment

How to choose a credentialing service

Who this is for: New practices, providers joining an existing group, practices adding a new location or tax ID, and any group re-credentialing more than three providers at once.

The decision framework

  1. 01Separate credentialing from enrollment

    Credentialing (verifying identity, license, education, and history) and enrollment (getting on a payer's panel and fee schedule) are two different workflows. A good vendor is explicit about which they do and which they hand off. If a vendor blurs the two in their quote, you'll be surprised at go-live.

  2. 02Own your NPI, CAQH, and PECOS accounts

    The vendor should work inside your accounts, not create parallel ones they control. Log-in credentials to CAQH, PECOS, and the state licensing portals stay with the practice. If a vendor asks to 'own' these on your behalf, walk away.

  3. 03Ask for the payer list, not the total

    A quote of '$5,000 for full credentialing' is meaningless without the payer list. Get a per-payer, per-provider breakdown. Understand which payers are closed panels in your area — no vendor can conjure a panel that is not accepting new providers, and any that claims otherwise is misrepresenting.

  4. 04Get the follow-up cadence in writing

    Payer applications go silent. The difference between a 90-day enrollment and a 210-day enrollment is who calls the payer credentialing rep every two weeks. Insist on: weekly status updates by payer, escalation contacts, and a hard SLA on time-to-first-follow-up after silence.

  5. 05Understand realistic timelines

    Medicare (PECOS): 45–90 days. Medicaid: 60–180 days depending on state. Commercial payers: 90–150 days. BCBS plans: highly variable by state, often the slowest. Anyone quoting universal 30-day turnaround is either only doing Medicare or setting you up to blame the payer later.

  6. 06Confirm re-credentialing and roster maintenance

    Enrollment is not one-and-done. Every payer re-credentials every 2–3 years. Ask if ongoing roster maintenance, CAQH re-attestation (every 120 days), and re-credentialing are included or billed separately.

  7. 07Read the exit clause

    At termination, the vendor should hand back a clean file per provider per payer: contract effective date, provider ID numbers, portal logins, and any pending applications. Get this in the contract.

Common mistakes

  • Waiting until after lease signing and hiring to start credentialing — a 90-day process starts before you open the doors.
  • Assuming a new provider can bill under a group's tax ID without their own enrollment on file.
  • Letting CAQH lapse and re-attestation fail — payers pull it silently and terminate.
  • Not confirming panel status (open vs closed) before spending on an application.
  • Treating one credentialing contact per payer as sufficient; escalation contacts matter.

Red flags — walk away

  • Refuses to share credentials to CAQH, PECOS, or state portals with the practice.
  • Quotes a single flat number without a per-payer breakdown.
  • Promises 30-day universal turnaround across all payers.
  • Cannot show a sample weekly status report from an existing client.
  • Bundles credentialing 'free' with a billing contract you have not fully negotiated.

Frequently asked questions

How long does medical credentialing take?+

Realistic ranges by payer: Medicare 45–90 days, Medicaid 60–180 days depending on state, commercial payers 90–150 days, and BCBS plans anywhere from 90 to 210 days depending on state. A full enrollment cycle for a new provider across a typical payer mix runs 90–150 days.

What does credentialing cost?+

Expect $100–$300 per payer per provider for initial enrollment through a service, plus optional monthly maintenance of $30–$100 per provider. Flat 'full credentialing' quotes without a per-payer breakdown almost always exclude something material.

Can I do credentialing myself?+

Yes, and many single-provider practices do. Plan for 20–40 hours of upfront work to build CAQH, PECOS, and payer applications, then 1–3 hours per week of follow-up per payer for three to five months. If your time is worth more than $50 per hour, a competent service typically pays for itself.

What is CAQH and do I need it?+

CAQH ProView is a shared credentialing database most commercial payers pull from. You attest to your information every 120 days. Any US provider treating commercial insurance patients needs a current CAQH profile.

Can I bill under a group's tax ID before my own enrollment is complete?+

In most cases, no. Payer contracts tie to the individual provider's NPI enrolled under that group's tax ID. A few payers allow retroactive effective dates, but planning around retro-billing is a bad idea. Start credentialing a new hire 90 days before their start date.

What's the difference between credentialing, enrollment, and privileging?+

Credentialing is verifying a provider's identity, license, education, and history. Enrollment is adding that provider to a specific payer's panel and fee schedule. Privileging is a hospital granting a provider permission to perform specific procedures. All three overlap in vocabulary and none substitute for the others.
