How to Get Credentialed with Insurance Companies (2026)
Getting credentialed with insurance companies requires NPI registration, CAQH ProView setup, Medicare PECOS enrollment, and simultaneous commercial payer applications. This guide covers every step for 2026.
Step 1: NPI Registration
Type 1 NPI for individual providers, Type 2 for organizations. Apply at nppes.cms.hhs.gov. NPPES address must match CAQH exactly.
Step 2: CAQH ProView
Required by 1,000+ health plans. Build complete profile, attest every 90–120 days, authorize all target payers. See our CAQH setup guide.
Step 3: Medicare PECOS
Submit CMS-855I, 855B, 855R simultaneously. Timeline: 45–90 days. See our Medicare PECOS guide.
Step 4: Commercial Payers — All Simultaneously
Submit to Aetna, UHC, BCBS, Cigna, Humana on the same day CAQH is complete.
Step 5: Weekly Follow-Up and Deficiency Response
Follow up every 7–10 days. Respond to deficiency notices within 24 hours. ProEnrollment achieves 99.4% approval rate and 40% faster timelines. Free consultation.
The Document Checklist Payers Actually Require
Before any application goes out, assemble: state license(s), DEA certificate, malpractice face sheet showing current coverage and 5-year history, board certification or training documentation, NPI confirmation matching your practice address, W-9 and practice tax documents, and a CV with month-and-year work history (gaps over 30 days need written explanation). Payers verify all of it against primary sources — discrepancies between your CV and CAQH dates are a top-three denial cause.
The Five Stages of Every Credentialing Application
Stage 1: CAQH completion and attestation (1–2 weeks if starting fresh). Stage 2: application submission with payer-specific forms. Stage 3: primary source verification — the payer confirms license, education, and history directly (30–60 days, where most of the timeline lives). Stage 4: committee review, typically meeting monthly — miss a cycle and you wait for the next. Stage 5: contracting and effective date issuance. Weekly follow-up during stages 3–4 is the single biggest controllable timeline factor: applications with no follow-up routinely take twice as long.
