Diagnosis Categories
AAPC's diagnosis taxonomy, which ladders ICD-10-CM 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. Served live from the taxonomy API.
Browse the hierarchy below (expanding a category loads its child categories), or search to query the entire set.
