Flexion deformity, right knee

This code signifies a fixed or persistent bending of the right knee joint, limiting its ability to fully extend. This deformity can result from various underlying conditions, leading to restricted range of motion and functional impairment.

Use this code when documentation clearly indicates a flexion deformity specifically affecting the right knee. This is appropriate for conditions such as contractures, arthrofibrosis, or other pathologies causing a permanent bent position of the joint.

• Ensure documentation specifies "right knee" to support laterality.
• Distinguish from temporary flexion due to pain or swelling; this code implies a fixed deformity.
• Code any underlying cause of the flexion deformity (e.g., arthritis, trauma) as a primary diagnosis if applicable.
