Ankylosis, right wrist

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

Use this code when documentation explicitly states ankylosis of the right wrist. This diagnosis is typically supported by imaging studies (e.g., X-rays, CT scans) demonstrating joint fusion, and clinical notes detailing the patient's limited wrist mobility and associated symptoms.

• Ensure laterality is clearly documented as "right wrist" to avoid miscoding.
• Distinguish from arthrodesis (surgical fusion), which has different coding.
• Code any underlying cause of the ankylosis (e.g., rheumatoid arthritis, fracture sequela) as an additional diagnosis.
