Look up codes, validate codes, and expand value sets through a standards-based FHIR terminology service, so you don't have to host one yourself. LOINC, RxNorm and ICD-10-CM are supported today, with RxNorm scoped to the Current Prescribable Content set and ICD-10-CM's every code, including which are valid for submission. More code systems and operations are coming.
