How to Join the Aetna Network

Complete step-by-step guide to Aetna credentialing, requirements, and timelines for healthcare providers

Overview

Joining the Aetna provider network opens your practice to millions of potential patients. Aetna is one of the largest health insurance companies in the United States, serving both commercial and Medicare Advantage populations.

This comprehensive guide walks you through the entire credentialing process, from initial application to receiving your first payments.

Step 1: Determine Your Eligibility

Before applying, ensure you meet Aetna's basic requirements:

  • Current, unrestricted license to practice in your state
  • Board certification in your specialty (strongly preferred)
  • Malpractice insurance with minimum $1M/$3M coverage
  • DEA registration (if prescribing controlled substances)
  • Clean professional history (no sanctions or disciplinary actions)
  • National Provider Identifier (NPI)

Important Note

Aetna networks vary by state and plan type. You may need to apply separately for different Aetna subsidiaries (e.g., Aetna Better Health for Medicaid). Check which specific networks you want to join.

Step 2: Complete Your CAQH Profile

Aetna uses the Council for Affordable Quality Healthcare (CAQH) ProView for primary source verification.
