Other ossification of muscle, right shoulder

This code signifies the abnormal formation of bone tissue within the muscle of the right shoulder, a condition known as heterotopic ossification or myositis ossificans. This process involves the transformation of soft tissue into bone, often following trauma or surgery, leading to pain and restricted range of motion.

Utilize this code when documentation explicitly states ossification or heterotopic bone formation within the musculature of the right shoulder. This typically occurs in post-traumatic or post-surgical settings, or in cases of myositis ossificans affecting this specific anatomical site. Supporting documentation should include imaging reports (e.g., X-ray, CT scan) confirming the presence and location of the ossification.

• Ensure laterality is precisely documented and matches the code (right shoulder).
• Differentiate from calcification, which is the deposition of calcium salts but not true bone formation.
• Consider an external cause code if the ossification is post-traumatic.
