What This Code Means
M60.000 is the ICD-10-CM diagnosis code for infective myositis, unspecified right arm. Infection of the muscle tissue in the right arm, causing inflammation and pain in the arm muscles. M60.000 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).
M60.000 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 the causative organism if documented, as it may require an additional code.
