Description
Issue noted by CMS BlueButton API Team
| The Eob Outpatient profiles contains the following invariant: Care Team Performing physician's qualifications are from US-Core-Provider-Specialty Value Set: ( role.where(coding.where(code in ('performing' )).exists()).exists() implies role.where(coding.where(code in ('performing')).exists()).exists().qualification.memberOf('http://hl7.org/fhir/us/core/ValueSet/us-core-provider-specialty') ) When we supply a resource with a careTeam.role of performing provider and the associated qualification, we still get validator errors. I believe the FHIRPath above is incorrect. The expression*after* the IMPLIES operator (the "RHS") cannot properly resolve to the qualification attribute. If you take just the RHS expression, and then remove the .memberOf call, and run that fhirPath expression against a resource with a proper qualification, it does NOT return the qualificationelement. In other words, the following expression returns an empty value: |
careTeam.role.where(coding.where(code in ('performing')).exists()).exists().qualification
The expression above gets down to the careTeam.role level before any criteria is applied. Qualification is a sibling of role, not a child. The following expression correctly reaches the qualificationattribute
careTeam.where(role.coding.where(code in ('performing'))).qualification
I believe the proper RHS expression is this:
careTeam.where(role.coding.where(code in ('performing'))).qualification.memberOf('http://hl7.org/fhir/us/core/ValueSet/us-core-provider-specialty')
Note that there are no examples in the IG demonstrating the proper coding of a performing provider with qualification
