I think the default set of CodeSystem url is here https://github.com/hapifhir/hapi-fhir/blob/c844c3f5765994be8fffa7553936069efc4b81b6/hapi-fhir-storage/src/main/java/ca/uhn/fhir/jpa/term/api/ITermLoaderSvc.java#L35-L40.

https://github.com/hapifhir/hapi-fhir/blob/8a44e1058fb0e0e063a152882e1f0dbbd15e1d10/hapi-fhir-jpaserver-base/src/main/java/ca/uhn/fhir/jpa/term/TermReadSvcImpl.java#L1646-L1671 I think is because of there is only "is-a" and "descendent-of" in the original HAPI-FHIR code. Therefore we can't use other operator... But i don't know how to write...

Hi @kaicode I have tried to [fix this problem](https://github.com/hapifhir/hapi-fhir/pull/7012) in hapi-fhir. Is there anything I can do more with snowstorm? But I can't find the logic about this in snowstorm...

Thanks 🙏🏻

@kaicode Could I add filtering with ICD-10-X here? Or I should keep it not supported? https://github.com/IHTSDO/snowstorm/blob/2e7f8cad99335e672dcf9e0d69c3b391b30f71e6/src/main/java/org/snomed/snowstorm/fhir/services/FHIRValueSetService.java#L921-L923
