Contracture, right knee

This code signifies a persistent limitation in the range of motion of the right knee joint, where the joint is fixed in a flexed or extended position, preventing full extension or flexion. This restriction can be due to changes in the joint capsule, ligaments, muscles, or tendons surrounding the knee. It results in functional impairment and often pain.

Apply this code when documentation clearly indicates a contracture affecting the right knee. This is typically supported by physical examination findings noting decreased active and passive range of motion, and often by imaging studies confirming structural changes. Use this code for conditions such as arthrofibrosis, post-traumatic stiffness, or chronic inflammatory conditions leading to fixed knee deformity.

• Ensure laterality is accurately documented; differentiate between right, left, and bilateral knee involvement.
• Do not confuse with knee stiffness (M25.66-) without a fixed limitation of movement.
• Always look for an underlying cause (e.g., arthritis, trauma, neurological condition) to code in conjunction with the contracture, if documented.
