description: 'The Defense Health Agency (DHA) is a joint, integrated combat support agency that enables the Army, Navy, and
  Air Force medical services to provide a medically ready force and ready medical force to combatant commands. DHA operates
  the Military Health System (MHS), MHS Genesis electronic health record, the Military Health System Data Repository (MDR),
  and the Enterprise Intelligence and Data Solutions (EIDS) program. Data exchange inside MHS Genesis uses SMART on FHIR APIs,
  but DHA does not currently publish a general-purpose public developer API, a developer portal, or any machine-readable API
  contract. What it does publish is human-readable interface documentation: 32 Interface Control Documents for MHS Data Repository
  feeds, plus MDR and M2 data dictionaries and access guides, all distributed as .DOCX and .PDF through the Health.mil Reference
  Center.'

  note: Corrected 2026-09-07. The previous `freemium` value was derived from a bulk-sweep plans scaffold that invented Free/Professional/Enterprise
    tiers. DHA publishes no plans and no pricing; MHS GENESIS interface access is restricted to vetted DoD application partners
    and MDR/M2 accounts are granted on request.

  detail: DHA's only published interface reference is a set of 32 Interface Control Documents for MHS Data Repository feeds,
    served as .DOCX and .PDF from the Health.mil Reference Center, with no OpenAPI, FHIR CapabilityStatement, WSDL or .proto
    anywhere on health.mil, dha.mil or tricare.mil, and the developer request path behind them (info.health.mil) is served
    under a DoD-internal PKI certificate that no public client can complete a TLS handshake with.
