"In modifier is unsupported" is being thrown

[revans2023]

I see the following exception being thrown when doing a basic "IN" CQL statement like [Observation: "HbA1c Laboratory Test"]:

org.opencds.cqf.cql.engine.exception.CqlException: Error evaluating expression Exclusions: In modifier is unsupported

which is in the following file in the "isMatchCoding" method: https://github.com/cqframework/clinical-reasoning/blob/master/cqf-fhir-utility/src/main/java/org/opencds/cqf/fhir/utility/matcher/ResourceMatcher.java#L214

This method is not being overwritten by either R4 or R5 classes.

This is caused by this CQL looking for Observation lab values with codes in the "HbA1c Laboratory Test" ValueSet:

library RT2DM version '1.0.0' using FHIR version '4.0.1' include FHIRHelpers version '4.0.1' called FHIRHelpers valueset "HbA1c Laboratory Test": 'http://cts.nlm.nih.gov/fhir/ValueSet/2.16.840.1.113883.3.464.1003.198.12.1013' context Patient define "Has A1c Lab": [Observation: "HbA1c Laboratory Test"] A1cLab where A1cLab.status ~ 'final' return A1cLab

Take a look at this Zulip thread. The short version is that this behavior is configurable: https://chat.fhir.org/#narrow/stream/179220-cql/topic/In.20modifier.20is.20unsupported/near/423489106
