Aetna Provider EDI Connectivity
HIPAA X12 electronic data interchange for health care professionals - EDI 837 claims, 270/271 eligibility and benefits, 276/277 claim status and 835 remittance advice. This is not an Aetna-hosted REST API and Aetna publishes no machine-readable contract for it; connectivity runs through the Availity provider portal and through clearinghouses, against the ASC X12 5010 and NCPDP D.0 transaction standards Aetna documents on aetna.com.
