Procedure Categories

AAPC's procedure taxonomy, which ladders CPT, HCPCS Level II, and ICD-10-PCS codes up into a browsable hierarchy of categories. AggKnowledge republishes it unmodified and assigns each category a stable AggKnowledge category ID. Expand any category to see its children, or search the full set by name. Underlying procedure codes are not shown. Served live from the taxonomy API.

Browse the hierarchy below (expanding a category loads its child categories), or search to query the entire set.
