What This Code Means

M79.606 is the ICD-10-CM diagnosis code for pain in leg, unspecified. Pain in the leg when the specific side (right or left) is not documented or cannot be determined. M79.606 sits in the ICD-10-CM chapter for diseases of the musculoskeletal system and connective tissue (m00-m99), within the section covering other soft tissue disorders (m70-m79).

M79.606 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 documentation does not specify right or left side.
