Frequently asked questions
Optum scores C on the API Report Card. A self-serve developer portal at developer.optum.com offers eligibility, claims, remittance, attachment, and FHIR APIs with sandbox access. Production onboarding is enterprise-qualified but documented and self-directed. The claims APIs demand real X12 EDI expertise.
Optum has an official API, but teams routinely hit its limits: gated access, partial coverage, or paid tiers. Most end up supplementing it with exports or an unofficial API layer like Supergood.
Optum is UnitedHealth Group's health-services arm spanning care delivery (OptumHealth), pharmacy (OptumRx), data/analytics and revenue-cycle technology (OptumInsight, which absorbed Change Healthcare).
Healthcare RCM / Billing (clearinghouse + analytics), Typically for providers, payers, pharmacies, and health-tech partners, plus individual members. Providers and health-tech vendors submit eligibility (270/271), claims (837), status (276/277), and consume remittance (835) and FHIR data through Optum/Change Healthcare; payers connect via the clearinghouse network.
UnitedHealth subsidiary; one of the largest healthcare-services and clearinghouse operations in the US, processing a very large share of national medical claims.
Mixed, Holds enormous healthcare data, but as a clearinghouse/network it largely owns aggregated payer-connectivity and claims-routing data rather than being a customer's own trapped system-of-record (inverted data flow).
Optum founded 2011; Change Healthcare lineage older. Modern developer portal with FHIR and REST wrappers over X12 EDI.
Sandbox/production access requires formal request/qualification. Steep X12 EDI learning curve for FHIR/claims APIs. Full sourced list under Sources below.
Common alternatives include Availity, Waystar, Experian Health, TriZetto (Cognizant), Inovalon. Graded alternatives appear under "More from the report card" below.
Grades measure one thing: can a customer's engineering team get their own data out programmatically? We check six things (whether a real API exists, how access is gated, data coverage, auth quality, docs and developer experience, and stability) and roll them into a letter grade. Grades get re-verified, and they only move on evidence.
Yes. Supergood maintains an unofficial Optum API and MCP server so AI agents and internal tools can read and write Optum data. See the Optum integration docs at supergood.ai/docs/optum-api.
