Which option correctly lists interoperability standards used in health IT?

• A. HL7, LOINC, SNOMED CT, ICD-10-CM
• B. HL7, FHIR, LOINC, SNOMED CT, and ICD-10-CM
• C. FHIR, LOINC, SNOMED CT
• D. HL7, FHIR, ICD-10-CM

Answer: (B)

Interoperability in health IT depends on both how data is exchanged and how its meaning is standardized across systems. HL7 provides the established framework for health information exchange, while FHIR offers a modern, flexible way to share data over APIs that many systems already use. For data to be understood consistently, the content needs standard codes: LOINC codes standardize lab tests and results, SNOMED CT provides a comprehensive clinical terminology for describing conditions and procedures, and ICD-10-CM supplies standardized diagnostic codes used in reporting and billing. Using all of these together covers messaging structure, data formats, and semantic meaning, which is essential for seamless exchange, interpretation, and use of health information. The other options miss one or more of these critical components, making them less capable of achieving full interoperability.
