Other calcification of muscle, right shoulder

This diagnosis code signifies the presence of abnormal calcium deposits within the muscle tissue of the patient's right shoulder, excluding those specifically classified as myositis ossificans traumatica or progressive. These calcifications can lead to pain, stiffness, and restricted range of motion in the affected shoulder.

This code is appropriate when documentation specifies calcification of a muscle in the right shoulder, without a clear traumatic origin or a diagnosis of progressive myositis ossificans. Supporting documentation typically includes imaging reports (e.g., X-ray, MRI) identifying the calcification and a physician's note confirming its location and ruling out other specific types of myositis ossificans.

• Ensure the documentation explicitly states "right shoulder" to justify laterality.
• Differentiate from M61.0- (Myositis ossificans traumatica) and M61.1- (Myositis ossificans progressiva) based on etiology and clinical presentation.
• Code any associated pain or functional limitations separately if documented.
