Who is Availity?

Your organization can submit and receive the following transactions through Availity's EDI Gateway:

  • 837 - Institutional Claims
  • 837 - Professional Claims
  • 837 - Dental Claims
  • 835 - Electronic Remittance Advice

Please note: All trading partners must use the Availity EDI Gateway to submit Anthem EDI transactions. The EDI gateway migration does not impact participation status with Anthem or how Anthem adjudicates claims.
