athenahealth is a cloud-based electronic health records (EHR), medical billing, and practice management company founded in 1997 and headquartered in Watertown, Massachusetts.

The company serves ambulatory practices ranging from solo physicians to large health systems and medical groups. Its continuously updated rules engine processes millions of payer transactions daily, enabling higher clean claim rates and faster reimbursement compared to on-premise EHR alternatives. athenahealth holds an 18.15% share of the US ambulatory EHR market.\n\nathenahealth is currently owned by a private equity consortium of Bain Capital and Hellman & Friedman, which acquired the company in 2019 for $5.7 billion. Annual revenue stands at approximately $1.7 billion. The company competes with Epic, eClinicalWorks, and Oracle Health in the ambulatory EHR market. Its managed-service model, shared payer network data, and cloud-native infrastructure continue to make it a compelling choice for ambulatory providers who prioritize revenue cycle performance and reduced administrative burden.
