USCDI Compliance and PractitionerRole Resource

Deidre StufferJan 22 2026

Hello,

I have been directed here to ask about USCDI compliance and the Millennium R4 APIs. PractitionerRole is a required resource to support per US Core profiles. I was told that there's no plan to implement the PractitionerRole API because Millennium was built in such a way it cannot support it.

How am I to obtain PractitionerRole data from Millennium with the absence of the API? The CareTeamRole resource is too fine-grained. The PractitionerRole resource is “to cover all the places that the practitioner is allocated to work (and specific details relevant to that role - such as a specific contact number, or electronic services endpoint)”. I need information that would be provided from PractitionerRole.Specialty and PractitionerRole.Code. Can you please explain to me how Millennium is USCDI compliant and where I'm able to obtain the PractitionerRole information I need?
