Contracture of muscle, right ankle and foot

This code signifies a persistent shortening or tightening of the muscles in the right ankle and/or foot, leading to restricted range of motion. This can result from various underlying conditions, including neurological disorders, trauma, or prolonged immobilization.

Apply this code when documentation clearly indicates a contracture affecting the muscles of the patient's right ankle and/or foot. Supporting documentation should specify the laterality and the presence of limited joint movement due to muscle shortening.

• Ensure the documentation specifies "right" ankle and foot; do not use for bilateral or left-sided contractures.
• Distinguish from muscle spasm or stiffness; contracture implies a fixed or semi-fixed limitation of movement.
• Code any underlying cause of the contracture, if known, as an additional diagnosis.
