It is currently implemented as a standard vocabulary, with OMOP-generated hierarchical relations to Procedure concepts from SNOMED CT vocabulary and other relationships mimicking SNOMED CT's internal model.+ICD10PCS, often spelled "​ICD-10-PCS",​ is a vocabulary in the USA for coding hospital-based medical procedures.

-Currently all concepts from the ICD10PCS Vocabulary belong to the Procedure domain. Some of them may relate to taking Measurements or administering Drugs in a clinical setting, but rely on other coding systems to specify important details (results of measurements or exact drug and dose that was administered). ICD10PCS concepts themselves still represent only the nature of actions performed by provider.+Currently all concepts from the ICD10PCS Vocabulary belong to the [[documentation:​vocabulary:​procedure|Procedure]] domain.

 Internal ICD10PCS hierarchy is straightforward with each concept always having only one immediate ancestor. Leaf-level concepts also have multiple hierarchical relations to SNOMED CT concepts from procedure subhierarchy as terminal descendants. Both hierarchical trees exist in parallel. Internal ICD10PCS hierarchy is straightforward with each concept always having only one immediate ancestor.
