Using LOINC with FHIR
summary
FHIR serves as the delivery vehicle for LOINC which provides ~90,000 variables and is present in systems covering hundreds of millions of patients with billions of results; releases ship twice yearly and the terminology server runs via Smile CDR. You can look up full term metadata via CodeSystem, ValueSet, ConceptMap, pull predefined subsets (radiology playbook, top 2000 labs) or LOINC groups (LG) and use mappings to ICD/RT, RadLex, RxNorm; apps like SMART on FHIR and Apple Health work across EHRs when sources map to LOINC.
