description: >-
  Change Healthcare was acquired by UnitedHealth Group and folded into Optum. Its developer
  surface has been migrated off changehealthcare.com onto Optum infrastructure, and the
  changehealthcare.com API gateway has been retired. This artifact records that migration with
  the provider's own published notice, plus the status page that is still reachable on a
  changehealthcare.com host.
versioning:
  scheme: uri-path
  note: >-
    Optum's published guidance for the Medical Network APIs (formerly Change Healthcare Medical
    Network) states that versioning is managed through the URL path. The v2-era
    "Accept: application/vnd.changehealthcare.medicaleligibility-v2+json" media-type header is
    explicitly marked DEPRECATED and no longer needs to be sent or incremented.

    component list covers the pharmacy solutions line, not the Medical Network APIs.

  note: >-
    The Change Healthcare Medical Network API contracts (Eligibility v3, Professional Claims v3,
    Institutional Claims v1, Claim Status v2, Claims Responses and Reports v2, Attachments
    submission/status/retrieval, Payer List, Prior Authorization) are published by Optum at
    developer.optum.com and are already harvested in the Optum profile. They are deliberately NOT
    duplicated here: every servers[] block in those specs names an *.optum.com host, so per the
    ownership rule the contracts belong to Optum, not to this brand.
