How to Get Credentialed with Insurance Companies
Getting credentialed with insurance companies is how a provider becomes in-network and gets paid by a payer. The process is not hard to understand, but it is easy to stall on a missing document or a skipped follow-up. Here is the full sequence, how long it takes, and where it usually goes wrong.
What credentialing with insurance means
Credentialing is the payer’s process of verifying a provider’s qualifications and adding them to its network. Until it is complete, claims to that insurer are usually denied, and the denials often cannot be appealed. Credentialing has two linked parts: verifying your credentials (licenses, education, work history) and enrolling and contracting you with each payer so you receive an in-network effective date.
Step by step: how to get credentialed
- Get your NPI. Every provider needs a Type 1 (individual) NPI, and a group or practice needs a Type 2. You register for these free through NPPES.
- Gather your documents. Collect your state license, DEA registration, malpractice insurance (COI), board certificates, diploma, CV with no unexplained gaps, and a government ID. Most delays start here.
- Build and attest your CAQH profile. Most commercial payers pull your information from CAQH ProView. Create the profile, upload every document, and attest. Re-attest every 120 days so payers never pull an outdated record.
- Apply to each payer. Submit an enrollment application to Medicare (through PECOS), Medicaid (through your state), and each commercial payer (Aetna, Cigna, UnitedHealthcare, BCBS, Humana, and others). Each has its own forms and requirements.
- Follow up every week. Applications sit in queues. Call and check portals weekly, answer any payer requests quickly, and keep a tracker of where each application stands.
- Confirm the effective date. When contracting finishes, the payer issues an in-network effective date. Get it in writing. You can bill that payer for dates of service on or after that date, not before.
- Track revalidation. Credentialing is not one and done. Commercial payers re-credential every two to three years, and Medicare requires revalidation every five years (three for DMEPOS). Missing a deadline can deactivate you.
How long does it take?
Plan for 90 to 120 days end to end. Commercial payers commonly take 60 to 120 days, and Medicare or Medicaid 45 to 90 days. The payer’s own review and primary-source verification is the longest and least controllable stage, which is why starting early, before a provider’s start date, matters so much. We cover the full breakdown in the credentialing process and timeline.
The mistakes that cause delays
- Incomplete applications that get returned for rework, the single biggest cause of delay.
- An un-attested or outdated CAQH profile.
- Expired documents (license, DEA, or malpractice) sitting in the file.
- No follow-up, so an application sits idle in a queue for weeks.
- Billing before the effective date, which produces denials you cannot appeal.
Should you do it yourself or use a service?
A single provider joining one or two payers can manage credentialing alone with patience and a good tracker. It becomes much harder across many payers, a group, or a new practice, where one missed follow-up delays revenue for months. A credentialing service submits clean applications the first time and chases every payer to approval. At PRMS, provider credentialing and enrollment are handled end to end, and they are free for our billing clients.

FAQs
How do I get credentialed with insurance companies?
Register your NPI, gather your documents, build and attest a CAQH profile, then submit an enrollment application to each payer (Medicare via PECOS, Medicaid via your state, and each commercial payer). Follow up weekly until the payer issues an in-network effective date.
How long does insurance credentialing take?
Plan for 90 to 120 days end to end. Commercial payers commonly take 60 to 120 days and Medicare or Medicaid 45 to 90 days. Submitting complete applications and following up weekly is what keeps the timeline short.
Can I bill before I am credentialed?
Generally no. Claims for dates of service before your in-network effective date are usually denied with no appeal. Some payers allow limited retroactive billing, but you should confirm each payer’s policy before rendering services.
Do I need CAQH to get credentialed?
For most commercial payers, yes. They pull your information from your CAQH ProView profile, so it must be complete, current, and attested. Medicare and Medicaid use their own systems (PECOS and state portals).
