# PAS Temporary Codes - Da Vinci Prior Authorization Support (PAS) FHIR IG v2.2.0-ballot

## CodeSystem: PAS Temporary Codes 

 
Codes temporarily defined as part of the PAS implementation guide. These will eventually migrate into an officially maintained terminology (likely either SNOMED CT or HL7's UTG code systems). 

This Code system is referenced in the definition of the following value sets:

* [MetricDataSource](ValueSet-MetricDataSource.md)
* [PASCommunicationRequestMedium](ValueSet-PASCommunicationRequestMedium.md)
* [PASInformationChangeMode](ValueSet-PASInformationChangeMode.md)
* [PASSupportingInfoType](ValueSet-PASSupportingInfoType.md)
* [PASTaskCodes](ValueSet-PASTaskCodes.md)
* [X12278DiagnosisType](ValueSet-X12278DiagnosisType.md)
