Which code system goes where?

A FHIR CodeableConcept doesn't tell you which terminology belongs in it. Pick a concept to see the code-system family that's legal there — and which ones are clinical, which are for the claim, and which are licensed.

Most fields accept a small family of systems, not one — usually split by who codes it (the record vs the claim). Licensed systems here are named, not reproduced: this Lab points at CPT, SNOMED CT, and the X12 code lists, it never hosts them. For the written version, see the library card.

ICD-10-CM is what the payer expects on the claim; SNOMED CT is the clinical view in the record.

  • SNOMED CTLicensed — named, not hosted

    Clinical terms — problems, findings, and procedures — used in the record rather than on the claim. A license is required; in the US it is free through the NLM UMLS.
