Coding

The Coding FHIR resource maps to the CodeSet object in Salesforce.

FHIR V4.0 - Clinical Data Model Mapping

Here’s how the fields defined by FHIR for Coding map to the fields in Salesforce.

Table 1. Coding - Salesforce
Coding Resource	Salesforce Field	Type	Salesforce Cardinality	Notes
`system`	`CodeSet.SourceSystem`	String	0.1	FHIR defines `coding.system` as a URI. However, the Salesforce implementation of `CodeSet.SourceSystem` is a string because Salesforce doesn’t support the URI data type.
`version`	`CodeSet.SystemVersion`	String	0.1	N/A
`code`	`CodeSet.Code`	String	0.1	FHIR defines `coding.code` as a code data type. However, the Salesforce implementation of `CodeSet.Code` is a string because Salesforce doesn’t support the Code data type.
`display`	`CodeSet.Name`	String	0.1	N/A
`userSelected`	`CodeSet.IsPrimary`	Boolean	0.1	N/A
