As of this day, ICD10PCS source updates yearly and deprecates codes nearly each release, meaning they can not be used by care providers to report performed procedures anymore. However, since ICD10PCS vocabulary is Standard, our current approach of deprecating codes in CDM Vocabularies when source does it creates problems for people trying to use these codes, which are still abundant in existing records, for analysis.
This update, we are looking to “resurrect” all codes deprecated since addition to OMOP CDM and make them Standard together with their own internal hierarchy. To differentiate between active and deprecated codes, we are going to mark codes as Deprecated in concept_name field. This should serve as deterrent to using these codes as mapping targets from other vocabularies.
Eventually procedure Standardization process will lead to creating custom concepts inside SNOMED hierarchy to serve as mapping targets for deprecated ICD10PCS concepts, but this solution aims to keep existing ICD10PCS codes useful in short term.
