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

## Data Type Profile: PAS Quantity 

 
Constraints and extensions on SimpleQuantity which restricts the units. 

### Mandatory Data Elements

The following data elements must always be present.

§§ §prof-quant-1:**Each PAS Timing SHALL have at least one of:**

1. count (with optional countMax)
1. frequency and period and periodUnit (with optional frequencyMax and periodMax)
1. calendarPattern extension
1. deliveryPattern extension§ §§

Please see the documentation on the FHIR Timing datatype for more information of how common timing uses are represented.

**Usages:**
