Using FHIR Resources

You can use the FHIR Resources for a variety of use cases:

Querying for available code systems, codes, or value sets – (See CodeSystem Resource)
Translating source data into a reference (See ConceptMap Resource and $translate operation). This functionality is also available via the domain-specific standardize operations.
Grouping, categorizing, or enhancing codes (See ValueSet Resource and $classify operation). This functionality is also available via the domain-specific classify operations.

Use cases vary mostly in the source data domain (medications vs. problems vs. procedures, etc), value set scope (e.g., CCSR Category vs. LOINC - Component etc), and value set use (e.g., grouping vs. categorizing vs. enhancing).

Two of the most common use cases involving FHIR Resources are covered in detail:

Other common use cases are listed below in brief:
