Aetna Provider Enrollment & Credentialing

Aetna, now a subsidiary of CVS Health, is one of the largest commercial payers in the United States, serving more than 39 million members across employer, individual, Medicare, and Medicaid lines of business. For providers, enrollment with Aetna unlocks access to one of the broadest commercially insured patient populations in the country.

Aetna's credentialing is managed through the Availity Essentials portal, which serves as the primary submission gateway for most commercial payers. Because Aetna participates in the CAQH universal credentialing initiative, providers must maintain an up-to-date CAQH ProView profile before submitting an enrollment application. Attestation must be current — within the past 120 days — or Aetna will reject the application outright.

One area where Aetna's process diverges from other large carriers is its strict documentation requirements around malpractice history. Any malpractice settlement or judgment in the past 10 years requires a detailed written explanation and may trigger an extended review by the Aetna Credentialing Committee. Providers with a clean history typically see decisions in 60–75 days, while those with reportable events should budget 90 days or more.

Aetna also requires that group practices enroll at the group (Type 2 NPI) level in addition to individual provider enrollment. This two-track enrollment is a common source of delay for new practice groups — Arctic Health handles both tracks simultaneously to eliminate unnecessary lag time.
