athenahealth
athenahealth is a cloud-based electronic health record (EHR), revenue cycle management, and practice management platform serving ambulatory practices, hospitals, and health systems across the United States. The athenaOne platform spans patient engagement, scheduling, clinical documentation, ordering, e-prescribing, population health, and billing/claims. The athenahealth API surface exposes both a proprietary REST API and a Cures Act-certified FHIR R4 server with US Core / USCDI conformance, FHIR Subscriptions for event-driven webhooks, FHIR Bulk Data ($export) for population-scale data sharing, and CDS Hooks for embedded clinical decision support. The company is privately held by Veritas Capital and Hellman & Friedman following the 2022 take-private acquisition.
