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

This code signifies a partial dislocation of the upper part of the right shin bone (tibia) where it has shifted backward relative to the thigh bone (femur) at the knee joint. This injury implies that the joint surfaces are no longer perfectly aligned but still maintain some contact.

Apply this code for initial encounters involving patients presenting with a posterior subluxation of the proximal right tibia. This is typically seen following trauma, such as a direct blow to the front of the knee or a hyperextension injury. It's appropriate for the initial diagnosis and treatment phase of this specific knee injury.

• Ensure documentation specifies "posterior subluxation" and "proximal tibia" for the right knee.
• Confirm the encounter is the initial treatment for this injury, as indicated by the "A" seventh character.
• Distinguish from complete dislocations (luxations) or anterior subluxations.
