Availity

Availity is the nation's largest real-time health information network, facilitating secure information exchange between healthcare payers, providers, and health IT vendors. Founded in 2001 as a joint venture between Blue Cross and Blue Shield of Florida and Humana, Availity has grown into a critical healthcare infrastructure company serving the entire provider-payer ecosystem.

The platform connects more than one million providers with over 2,700 payers nationwide and processes more than 13 billion transactions annually. Availity's core service offerings include eligibility and benefits verification (X12 270/271), claim submission (X12 837), remittance posting (X12 835), claim status inquiries (X12 276/277), and prior authorization solutions. The company's Availity Essentials Pro product suite offers real-time eligibility integration directly into provider EHR workflows, enabling faster decision-making at point of care.

For ABA billing operations, Availity provides critical eligibility verification capabilities that allow behavioral health providers to confirm insurance coverage and authorized units before delivering services. The platform's multi-payer connectivity eliminates the need for providers to maintain separate relationships with hundreds of insurance companies.

Beyond core transaction processing, Availity has recently expanded its interoperability and clinical data capabilities through the acquisition of Diameter Health, integrating advanced data quality and upcycling technology into its clinical portfolio. The company is also developing enhanced prior authorization solutions in partnership with industry leaders to streamline administrative workflows.
