Every payer application draws on the same core set of documents, with additions by provider type and by state. Gather them once, keep them current, and every application after that becomes a matter of process rather than a scramble. Missing or expired documents are the leading cause of returned applications and the main reason credentialing timelines stretch past 150 days.
Use this checklist to assemble your file. If you would rather hand it to us, we collect and verify every item as the first step of any credentialing engagement.

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.
- 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.
- Profile setup
CAQH ProView, PECOS and payer portals are created or cleaned up, attested and linked to the correct Tax ID and locations.
- Application submission
Every enrollment is filed in dependency order, with a tracking record for each payer, date and reference number.
- Follow-up on a fixed cadence
Payers are contacted on a schedule. Requests for more information are answered the same business day.
- Approval, contract and handoff
Effective dates, provider IDs and fee schedules are logged and loaded into your billing system.
Frequently asked questions
How current do credentialing documents need to be?
Licenses, DEA and malpractice must be unexpired at the time of review and, for most payers, at the time of the committee decision. CAQH attestation must be within 120 days. We track every date so nothing is stale when the payer looks.
Do payers need original documents?
No. Clear digital copies are accepted everywhere. Payers verify at the primary source, so what they need from you is accurate information and legible copies. See primary source verification.
What if I have a malpractice claim or disciplinary history?
Disclose it, with a clear written explanation and any resolution documents. Payers verify against the NPDB and state boards, so non-disclosure is discovered and is far more damaging than the event itself.
Can ClainetRCM collect these documents for me?
Yes. Document collection and verification is the first step of every engagement, and we store the file so every future application, re-credentialing and revalidation starts from a complete set.
