Osteochondritis dissecans, unspecified shoulder

This code signifies a condition where a segment of cartilage and underlying bone separates from the articular surface within the shoulder joint. This osteochondral lesion can lead to pain, swelling, and mechanical symptoms such as clicking or locking. It represents an idiopathic process of subchondral bone necrosis and subsequent reossification.

Apply this code when documentation confirms a diagnosis of osteochondritis dissecans affecting the shoulder, but the specific laterality (right or left) is not specified. This diagnosis is typically made based on clinical presentation and confirmed with imaging studies such as X-rays, MRI, or CT scans.

• Only use this code when laterality is truly unspecified; otherwise, select a more specific code for the right or left shoulder.
• Ensure the documentation clearly states "osteochondritis dissecans" and not another form of osteochondrosis or arthritis.
• Do not confuse with osteochondrosis, which is a broader term for disorders of bone growth.
