You validate clinical codes by applying terminology validation through a user-operated FHIR terminology server. This confirms that SNOMED CT, RxNorm, LOINC, and ICD-10 codes are valid without bundling restricted vocabularies or sending patient notes to external services.

Yes, you can expand ValueSets with filters or SNOMED ECL. The terminology server processes bounded expansions, performs code lookups, and translates codes through ConceptMaps for interoperable clinical coding workflows.

You ground clinical entity spans into validated FHIR CodeableConcept structures by validating candidate codes against a licensed terminology server. It returns a coded FHIR CodeableConcept only when validation succeeds, preserving text-only fallbacks for invalid codes.

Yes, you must operate a user-managed FHIR terminology server. The skill requires version-aware requests, bounded expansions, and credential protection to perform code validation while strictly excluding PHI from terminology-service calls.

Limitations include the requirement to exclude PHI from terminology-service calls and the need for bounded expansions to manage server load. You must also handle credential protection and version-aware requests manually to ensure secure code validation.
