Healthcare Terminology & FHIR R4 Interoperability
Standardized coding guidelines governed by CodesForMD

In HL7 FHIR R4, discrete clinical findings and laboratory measurements are encapsulated inside Observation resources. Diagnostic terms and problem list entries are represented within Condition resources, while surgical and therapeutic acts map to Procedure. CodesForMD adheres to official US Core and International FHIR Implementation Guides.

An OID is an internationally standardized dotted-decimal identifier (e.g. 2.16.840.1.113883.6.1 for LOINC) registered with HL7 and ISO. OIDs ensure unambiguous identification of terminology authorities when exchanging clinical messages across heterogeneous EHR, LIS, and PACS systems.
