M62.519 ICD-10-CM Code: Muscle wasting and atrophy, not elsewhere classified, unspecified shoulder

M62.519 is the ICD-10-CM diagnosis code for muscle wasting and atrophy, not elsewhere classified, unspecified shoulder. Loss of muscle mass and weakening in the shoulder area when it is unclear whether it affects the right or left side. M62.519 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).

M62.519 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.

Use this code only when the shoulder is affected but laterality cannot be determined from documentation.
