POST /v1/search
Discovery with evidence.
Semantic search returns bounded, ranked concept candidates and identifies how a term matched. It supports a clinician or application finding a concept; it does not make an autonomous coding decision.
ReasonHealth Terminology API
Healthcare terminology, ready to run.
Find the right concepts and expand the value sets your workflows depend on. One immutable image brings the read-only API, terminology store, and matching retrieval model into your own environment.
01 / Terminology systems
A common language for healthcare data.
Bring diagnoses, observations, medications, and procedures into the same workflow. Each release keeps terminology content, API behavior, and retrieval together at a known version.
ICD-10-CM
Diagnoses
LOINC
Observations & tests
RxNorm
Medications
SNOMED CT

CPT*
Procedures & services
CPT® content requires an appropriate license from the American Medical Association (AMA) or an authorized distributor for your intended use. CPT is a registered trademark of the AMA. See AMA licensing details.
02 / Search & expand
Find candidates. Then determine what belongs.
Two deliberate operations for people, applications, and agents: discover relevant concepts, then evaluate membership against an explicit definition.
FHIR R4 ValueSet/$expand
Membership from definition.
Submit an explicit FHIR ValueSet and receive deterministic membership evaluated against the installed terminology release. Discovery never substitutes for a clinical definition.
03 / Delivery & access
One release. Your environment.
A subscription provides license-gated delivery of one immutable OCI archive per release. Verify the artifact, deploy its image digest, and retain the prior accepted digest for controlled rollback.
- Lite
Evaluate the contract.
A redistributable, incomplete fixture image for integration and evaluation. It is not a complete production corpus.
- Full
Operate protected content.
A qualified protected-content image for entitled customers with the applicable upstream terminology rights.
