Flexion deformity, left wrist

This code signifies a fixed bending or contracture of the left wrist joint, where the wrist is permanently held in a flexed position. This deformity restricts the normal range of motion and can impair hand and arm function. It is a structural abnormality, not merely a temporary positioning.

Use this code when documentation explicitly states a "flexion deformity" or "flexion contracture" of the left wrist. This typically arises from conditions like cerebral palsy, stroke, trauma, or chronic inflammatory arthritis. Physician notes should clearly indicate the laterality and the fixed nature of the flexion.

• Ensure documentation specifies "deformity" or "contracture" to differentiate from temporary flexion.
• Verify laterality; separate codes exist for the right wrist (M21.231) and unspecified wrist (M21.239).
• Consider sequencing this code after the underlying cause of the deformity, if known and actively treated.
