I am trying to load modifier_concept_id column in PROCEDURE_OCCURRENCE table. Please note this is NOT procedure_concept_id but modifier_concept_id. The source procedure modifier code are CPT and HCPCS procedure modifier codes. When I map the source procedure modifier to concept table, I found many records belong to Observation, Measurement, and Device domain instead of Procedure domain. If these records are procedure code, then I know they should load them to their respective domain. However they are not procedure code but procedure modifier (for modifier_concept_id field in PROCEDURE_OCCURRENCE table). So how should I handle this situation?
I tend to think to not consider domain information at all. In another word, just load all of them to PROCEDURE_OCCURRENCE table regardless of their domain. The reason for this is because it will truly reflect description for the underlying procedures. For example, here is a source data record (sensitive information has been removed):
Prc_cd 00840 is a procedure (Anesthesia for intraperitoneal procedures in lower abdomen including laparoscopy; not otherwise specified). Prc2_modr_cd QK is a HCPCS code meaning MEDICAL DIRECTION OF TWO, THREE, OR FOUR CONCURRENT ANESTHESIA PROCEDURES INVOLVING QUALIFIED INDIVIDUALS, and it belong to Observation domain. So I would like to put the this procedure modifier in the modifier_concept_id column in the PROCEDURE_OCCURRENCE table even though it is in the Observation domain. I would like to know the opinion of the community. Thanks.
