Is M61.272 an HCC code?
No. M61.272 is a billable ICD-10-CM code but does not map to any HCC category in V28, V24, ESRD, or RxHCC.
This code does not map to an HCC category in any model (V28, V24, ESRD, RxHCC).
What This Code Means
M61.272 is the ICD-10-CM diagnosis code for paralytic calcification and ossification of muscle, left ankle and foot. Abnormal bone and calcium deposits forming in the muscles of the left ankle and foot, typically occurring after paralysis or severe injury. M61.272 sits in the ICD-10-CM chapter for diseases of the musculoskeletal system and connective tissue (m00-m99), within the section covering disorders of muscles (m60-m63).
M61.272 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.
Confirm left ankle and foot are both involved; separate codes exist if only one anatomical area is affected.

Coding Tips
- •Confirm left ankle and foot are both involved; separate codes exist if only one anatomical area is affected
