Posterior sublux of proximal end of tibia, left knee, init

This code signifies a partial dislocation of the upper part of the shin bone (tibia) at the knee joint, where the tibia has shifted backward relative to the thigh bone (femur). This injury specifically affects the left knee and indicates that the patient is receiving initial treatment for this condition.

Apply this code when documentation clearly states a posterior subluxation of the proximal tibia in the left knee, such as following a traumatic event like a fall or sports injury. It is appropriate for the initial visit where the injury is diagnosed and treatment plans are established.

• Ensure the documentation specifies "posterior" and "subluxation" for the proximal tibia.
• Verify the laterality is "left knee" and the encounter type is "initial."
• Do not use for complete dislocations or chronic/recurrent subluxations.
