Medial sublux of proximal end of tibia, right knee, init

This code signifies a partial dislocation of the right tibia's upper end, specifically where it meets the femur at the knee joint, with the tibia shifting towards the midline of the body. This injury involves the articular surfaces of the knee losing their normal alignment but remaining in partial contact.

Apply this code when documenting an acute injury resulting in a medial subluxation of the proximal right tibia, such as from a direct blow to the knee or a twisting injury. It is appropriate for the initial treatment or evaluation of this specific knee instability.

• Ensure documentation clearly specifies "medial" subluxation and "proximal end of tibia" for the right knee.
• The "A" seventh character indicates an initial encounter for active treatment of the injury.
• Do not use for complete dislocations or chronic instability; those require different codes.
