Posterior sublux of proximal end of tibia, right knee, subs

This code signifies a partial dislocation of the upper part of the shin bone (tibia) at the right knee joint, where the tibia has shifted backward relative to the femur. This injury involves the knee's stability structures but does not represent a complete separation of the joint surfaces.

Apply this code when documenting follow-up care for a patient with a previously diagnosed posterior subluxation of the proximal right tibia. This includes subsequent visits for cast changes, physical therapy, medication management, or monitoring of healing and recovery after the initial treatment phase.

• Ensure the documentation clearly specifies "posterior subluxation" and not a complete dislocation.
• Verify that the encounter is for follow-up care, not the initial treatment of the injury.
• Confirm laterality is "right knee" as specified by the code.
