Ankylosis, right shoulder

This code signifies the pathological fusion or immobility of the right shoulder joint. This condition results in a significant loss of range of motion and functional impairment of the affected shoulder. It can be caused by various factors including trauma, inflammatory arthritis, or degenerative processes.

Apply this code when documentation explicitly states ankylosis of the right shoulder. This diagnosis is typically supported by imaging studies (e.g., X-rays, MRI) demonstrating joint fusion, and clinical notes detailing severe restriction of shoulder movement. Use this code for both primary and secondary ankylosis.

• Ensure laterality is clearly documented as "right shoulder" to support this specific code.
• Distinguish from adhesive capsulitis (frozen shoulder), which is a different condition involving stiffness without true bony fusion.
• Code any underlying cause of the ankylosis (e.g., rheumatoid arthritis, fracture) as an additional diagnosis.
