Revision hip or knee: which code do the parts support?
Tap what happened in the operation. You get the revision CPT code the descriptor supports, or a plain statement that none fits, plus the ICD-10 code with joint and side and the lines the note must carry.
Plain rules, not a model. Nothing is stored or sent. Your coder and you sign the claim.

Sources: CPT descriptors for 27134, 27137, 27138, 27091, 27486, 27487 and 27488 (AMA CPT). ICD-10-CM codes from the CMS ICD-10 code set, each checked at NLM Clinical Tables on October 27, 2026. Seventh character A: the revision is active treatment. Where a descriptor does not settle a case, the check picks nothing rather than a higher code.
