What This Code Means
M67.272 is the ICD-10-CM diagnosis code for synovial hypertrophy, not elsewhere classified, left ankle and foot. Abnormal thickening of the synovial membrane (tissue lining the joint) in the left ankle and foot, not classified elsewhere. M67.272 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).
M67.272 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.
Verify laterality is documented as left ankle and foot in the medical record.

Coding Tips
- •Verify laterality is documented as left ankle and foot in the medical record
