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

## Data Type Profile: PAS Timing 

 
PAS constraints on the Timing datatype used in the various service requests. 

### Mandatory Data Elements

The following data elements must always be present.

§§ §prof-tim-1:Each PAS Quantity SHALL have:**

1. a value
1. either a unit or a code and system.§ §§

§prof-tim-2:If a code is present, it **SHALL** use the X12 quantity units.§

**Usages:**

* Use this DataType Profile: [PAS Device Request](StructureDefinition-profile-devicerequest.md), [PAS Medication Request](StructureDefinition-profile-medicationrequest.md), [PAS Service Request](StructureDefinition-profile-servicerequest.md), [PAS Device Request](http://hl7.org/fhir/us/davinci-pas/STU2.1/StructureDefinition-profile-devicerequest.html)... Show 2 more, [PAS Medication Request](http://hl7.org/fhir/us/davinci-pas/STU2.1/StructureDefinition-profile-medicationrequest.html) and [PAS Service Request](http://hl7.org/fhir/us/davinci-pas/STU2.1/StructureDefinition-profile-servicerequest.html)
