M67.471 ICD-10-CM Code: Ganglion, right ankle and foot

M67.471 is the ICD-10-CM diagnosis code for ganglion, right ankle and foot. A benign fluid-filled cyst that develops on or near the joints and tendons of the right ankle and foot. M67.471 sits in the ICD-10-CM chapter for diseases of the musculoskeletal system and connective tissue (m00-m99), within the section covering disorders of synovium and tendon (m65-m67).

M67.471 is a billable ICD-10-CM code but does not map to a payment HCC under the CMS-HCC V28, V24, ESRD, or RxHCC risk adjustment models. It can be reported on Medicare Advantage encounter data submissions but it does not contribute to a beneficiary's RAF score and therefore does not affect risk-adjusted payments to the plan.

This code encompasses ganglions of the right ankle and foot as a combined anatomical region.
