Ankylosis, left wrist

This code signifies the pathological fusion or stiffening of the left wrist joint, resulting in significant loss of motion. Ankylosis can be caused by various factors, including severe arthritis, trauma, or infection, leading to a rigid joint.

Assign this code when documentation explicitly states ankylosis of the left wrist. This typically occurs following conditions like advanced osteoarthritis, rheumatoid arthritis, or post-traumatic arthritis where the joint surfaces have fused. Supporting documentation should include physician notes detailing the diagnosis and laterality.

• Ensure documentation specifies "ankylosis" and not just severe stiffness or limited range of motion, which may indicate other conditions.
• Verify laterality; this code is specific to the left wrist.
• Consider coding any underlying conditions (e.g., rheumatoid arthritis, osteoarthritis) as primary or secondary diagnoses as appropriate, following sequencing guidelines.
