What This Code Means
M61.342 is the ICD-10-CM diagnosis code for calcification and ossification of muscles associated with burns, left hand. Abnormal hardening and bone formation in the muscles of the left hand as a complication of burn injury. M61.342 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).
M61.342 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 requires documentation of the burn as the underlying cause; link to the original burn injury code.
