Credentialing playbook

Group Practice Credentialing

A group is credentialed once with each payer; every provider is then linked to that group contract. We manage the group agreements, add new providers quickly, remove departing ones cleanly, and keep the roster synchronized across every payer and location.

About 4 minute read. Reviewed September 2026 by the ClainetRCM credentialing team.

Group credentialing has two layers. The organization holds the contract and the Tax ID; each provider is credentialed individually and linked to the group's agreement. Getting a new provider payable means credentialing them and linking them, at every payer, for every location where they will work. Getting a departing provider off the roster matters just as much, because payments and directory listings follow the link.

ClainetRCM maintains the group's payer contracts and provider roster as one system. New hires are started before their first day, departures are processed immediately, and location changes are reflected everywhere they need to be.

Where this usually goes wrong

What ClainetRCM handles

One coordinator owns the file from intake to effective date, so you always know who to call and what is outstanding.

  • Group participation agreements established or verified with every payer
  • New provider onboarding started before the hire date, with CAQH, Medicare reassignment and payer linkage
  • Location additions and provider-to-location mapping across all payers
  • Departure processing: reassignment termination, payer roster removal and directory updates
  • Roster reconciliation against every payer on a quarterly cycle
  • Provider-level participation report for practice leadership

What changes when a provider joins or leaves

Provider joinsType 1 NPI confirmed, CAQH profile updated with the group location, Medicare 855R reassignment to the group, payer linkage requests under the group contract, directory listing added. See Medicare provider enrollment.
Provider leavesMedicare reassignment terminated, payer rosters updated, CAQH location removed, directory delisted, and the provider's own records left intact for their next employer.
Location addedMedicare and Medicaid location additions, CAQH location added for each provider practicing there, payer notifications, directory updates.
Ownership or Tax ID changeFull re-enrollment in most cases. Plan well ahead; see new practice credentialing.

Groups large enough to run their own credentialing may qualify for delegated credentialing.

How the work runs

The sequence is the same for every payer and provider type; what changes is which documents and portals each step touches.

  1. Intake and gap review

    Licenses, DEA, board certificates, malpractice, work history and NPI details are collected and compared against what each target payer asks for.

  2. Profile setup

    CAQH ProView, PECOS and payer portals are created or cleaned up, attested and linked to the correct Tax ID and locations.

  3. Application submission

    Every enrollment is filed in dependency order, with a tracking record for each payer, date and reference number.

  4. Follow-up on a fixed cadence

    Payers are contacted on a schedule. Requests for more information are answered the same business day.

  5. Approval, contract and handoff

    Effective dates, provider IDs and fee schedules are logged and loaded into your billing system.

Frequently asked questions

How long does it take to add a provider to a group?

If the group is already contracted, linking a credentialed provider takes 30 to 90 days per payer. A provider who has never been credentialed with a payer takes the full 90 to 150 days. Starting before the hire date is the only way to shorten the gap.

Can a new provider bill under the group before credentialing completes?

Medicare allows retroactive billing once the reassignment is approved. Commercial payers generally do not, and billing under another provider's name is not permitted. We advise on the options each of your payers allows.

What happens to a provider's contracts when they leave?

The provider's individual credentials belong to them, but the contract and reassignment belong to the group. We terminate the link so payments stop routing to the group, and the provider re-establishes participation with their next employer.

Do you manage credentialing for multi-location groups?

Yes. We maintain a provider-by-location-by-payer matrix and keep it current, which is where most group credentialing problems come from. See credentialing audit.
