Other calcification of muscle, left shoulder

This code signifies the presence of abnormal calcium deposits within the muscle tissue of the patient's left shoulder. These calcifications are not otherwise specified as myositis ossificans or other specific types of muscle calcification. It indicates a pathological accumulation of calcium salts in the muscle fibers or surrounding connective tissue.

Apply this code when documentation explicitly states "calcification of muscle, left shoulder" without further specification of the type of calcification. This diagnosis is typically supported by imaging studies such as X-rays, CT scans, or MRI that visualize the calcium deposits within the muscle.

• Ensure laterality is clearly documented as "left shoulder" to support this specific code.
• Distinguish from M61.40 (unspecified shoulder) or M61.411 (right shoulder) based on physician documentation.
• Do not use if the calcification is specifically identified as myositis ossificans (M61.0-M61.2 series) or other specified types.
