Using FHIR (DTSU 2.1/3, as of 2016-03-01).
We have a requirement to associate charges to an encounters. So I am trying to find a way to associate an Encounter resource with a Claim resource. Ideally (it seems), Claim would just have a Reference(Encounter), but it does not. Is there a way to capture this relationship that I'm not seeing? If not, would adding an extension to Claim that contains a Reference(Encounter) be appropriate to create this relationship?
For reference, here are the Claim and Encounter resource specs: http://hl7.org/fhir/claim.html http://hl7.org/fhir/encounter.html
Thanks!
