Medial dislocation of proximal end of tibia, left knee, init

This code signifies a specific injury involving the displacement of the upper part of the left shin bone (tibia) towards the inside of the knee joint, where it has lost its normal alignment with the thigh bone (femur). This is a complete separation of the joint surfaces.

This code is appropriate for the initial treatment of a patient presenting with a newly diagnosed medial dislocation of the proximal tibia in the left knee. This typically occurs due to significant trauma, such as a motor vehicle accident or a sports injury.

• Ensure documentation clearly specifies "medial" dislocation and "left" knee.
• Confirm this is the patient's first encounter for this specific injury, not a subsequent visit or sequela.
• Differentiate from subluxation, which is a partial dislocation, as this code represents a complete dislocation.
