What This Code Means
M61.311 is the ICD-10-CM diagnosis code for calcification and ossification of muscles associated with burns, right shoulder. Abnormal bone formation in the muscles of the right shoulder resulting from burn injuries. M61.311 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).
M61.311 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.
