Disorders of muscle in diseases classd elswhr, r shoulder

This code signifies a muscular disorder affecting the right shoulder that is a manifestation of another underlying disease process. It indicates that the primary pathology is not intrinsic to the muscle itself, but rather a secondary effect of a systemic or other classified condition.

Apply this code when documentation specifies a right shoulder muscle disorder explicitly linked to an underlying disease classified elsewhere, such as a metabolic myopathy or a muscular manifestation of an autoimmune disease. Supporting documentation should clearly identify both the muscle involvement in the right shoulder and the primary disease causing it.

• Always sequence the underlying disease first, as this code is a manifestation code.
• Ensure documentation specifies "right shoulder" and clarifies the muscle involvement is secondary to another condition.
• Avoid using this code for primary muscle disorders of the shoulder; those would fall under other M codes.
