Devoted Health

Devoted Health is a technology-enabled Medicare Advantage payer founded in 2017 and headquartered in Waltham, Massachusetts, backed by General Catalyst and Obvious Ventures. It publishes CMS-required interoperability APIs built on HL7 FHIR R4: a member-facing Patient Access API exposing claims (ExplanationOfBenefit), encounters, conditions, and medications; a public Provider & Pharmacy Directory API (Da Vinci PDEX Plan-Net); and a public Plan Coverage & Formularies API (PDEX US Drug Formulary). Member data access uses OAuth 2.0 / OpenID Connect with member consent under the 21st Century Cures Act, and third-party applications register with the interoperability team to receive credentials.

Devoted Health publishes 5 APIs on the APIs.io network, including Condition API, Encounter API, ExplanationOfBenefit API, and 2 more. Tagged areas include Company, Healthcare, Medicare Advantage, Health Insurance, and FHIR.

Devoted Health’s developer surface includes documentation, API reference, getting-started guide, signup flow, support, authentication, and 18 more developer resources.
