Credentialing playbook

Credentialing for a New Practice

Opening a practice means a dozen registrations and applications that depend on each other. Do them in the wrong order and the whole timeline slips. We run the sequence from entity formation to your first in-network claim, and we start early enough that you are payable when the doors open.

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

A new practice needs a legal entity, an EIN, a Type 2 NPI, a bank account, malpractice coverage, Medicare and Medicaid enrollment, a CAQH profile for each provider, and applications with every commercial payer worth joining. Each step depends on the one before it. Medicare will not enroll a group without an NPI; payers will not credential without CAQH; CAQH requires a practice location and Tax ID.

ClainetRCM maps the sequence for your state and specialty, starts the long-lead items first, and runs the rest in parallel. Practices that engage us four to six months before opening are usually in network with their key payers on day one.

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.

  • Startup sequence plan with dependencies and target dates for your state
  • Entity, EIN, Type 2 NPI and bank account coordination
  • Medicare group enrollment, provider reassignments and EFT
  • State Medicaid and managed care enrollment
  • CAQH profiles for every provider and commercial applications with prioritized payers
  • Termination of prior reassignments and contracts tied to the previous employer

The startup sequence, in order

  1. Entity and Tax ID

    Form the entity, obtain the EIN, open the bank account. See healthcare business registrations.

  2. NPIs and location

    Type 2 NPI for the practice, Type 1 NPIs confirmed for each provider, practice address and phone established. See NPI registration.

  3. Medicare and Medicaid

    Group enrollment, provider reassignments and EFT. State Medicaid and MCO applications in parallel. See Medicare provider enrollment.

  4. CAQH and commercial payers

    Profiles built and attested, then applications filed with every prioritized commercial plan at once. See insurance credentialing.

  5. Contracts and billing setup

    Fee schedules reviewed and loaded, clearinghouse and ERA enrollment completed, first claims filed.

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

When should I start credentialing for a new practice?

Four to six months before you plan to see patients. Medicare and CAQH can start as soon as the entity and NPI exist; commercial applications follow immediately. Starting later means opening with out-of-network status.

Can I use my credentials from my previous employer?

Your individual credentials transfer, but every payer contract and Medicare reassignment is tied to the old group's Tax ID. Each has to be re-established under the new practice, and the old ones should be terminated to avoid misdirected payments.

What can I bill while credentialing is pending?

Medicare allows retroactive billing once enrollment is approved. Most commercial payers do not. Some practices bill out of network or under a credentialed colleague where the payer allows it. We advise on what each of your payers permits.

Do you handle the business registrations too?

Yes. Entity formation, EIN, NPI, CLIA and PECOS are covered under our healthcare business registrations service, and we run them as part of the same startup plan.
