Description
There is ambiguity on the meaning of Coverage effectiveTime. It states in 6.2.7.1 that "The act/effectiveTime@value records the date when you checked the coverage for a patient, and applies for all policies within the coverage activity." I.e., it is when it is observed, but it does not provide a period during which the coverage is actually in effect. It then states "Details on a specific Policy coverage period, or self-pay period, systems can record an additional effectiveTime inside the Policy Activity." However, when going to Appendix A, 3.17 Policy Activity, there is no effectiveTime attribute capturing the coverage period that would be equivalent to FHIR US Core Coverage.period. Rather, it seems that /participant/time low and high for participant type "COV" would capture period. This, in combination with Jira CDA-20763, need to be addressed to clarify how one can assert the coverage period and assert whether coverage is present or absent.
Upon resolving the Jira and considering a clarification along these lines, a separate vote needs to be made to backport the clarification to 4.1.1 to ensure it is properly interpreted and supported for USCDI v3 based certification.
