Disorders of muscle in diseases classd elswhr, right hand

This code signifies a muscular disorder affecting the right hand, which is a manifestation or complication of another underlying disease process. It describes conditions where the primary pathology is elsewhere, but its effects are observed in the muscles of the right hand.

Apply this code when documentation clearly indicates a muscle disorder of the right hand secondary to a systemic disease, such as a metabolic disorder, inflammatory condition, or infectious process. The medical record must specify the underlying disease and the involvement of the right hand muscles.

• Always sequence the underlying disease code first, as this code is for a manifestation.
• Ensure documentation specifies "right hand" to differentiate from other hand or bilateral involvement.
• Do not use this code for primary muscle disorders of the hand; those would be found in other M codes without the "classified elsewhere" designation.
