Payer Enrollment Guide: Get In-Network with Every Major Payer
Payer enrollment is the process of applying to participate in an insurance company's provider network. Once enrolled, you can bill that payer for services rendered to their members. Without enrollment, you cannot bill insurance — period.

Required Documents for Payer Enrollment
Every payer requires these core documents: 1. Current state medical license(s) 2. DEA registration (prescribers) 3. Board certification or eligibility letter 4. Professional liability (malpractice) insurance 5. NPI number (Type 1 individual, Type 2 organizational) 6. CAQH ProView profile (attested) 7. Hospital privilege letters (if applicable) 8. CV/work history (no gaps > 30 days unexplained) 9. Completed W-9 10. Voided check or direct deposit form
Strategies to Speed Up Enrollment
Submit all applications simultaneously. Do not wait for one payer before starting the next. Each payer processes independently, so parallel submission is the fastest approach.
Keep CAQH ProView current. Re-attest every 120 days minimum. Stale CAQH profiles are the #1 reason applications are returned.
Follow up proactively. Check application status every 2 weeks. Payers process thousands of applications, and proactive follow-up keeps yours moving.
