Posterior sublux of proximal end of tibia, r knee, sequela

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 is a chronic condition, indicating that the initial injury has healed, but the patient is still experiencing residual effects or complications from that prior subluxation.

Apply this code when documenting the long-term consequences or late effects of a posterior subluxation of the right proximal tibia. This would include situations where a patient presents for treatment of chronic pain, instability, limited range of motion, or other persistent issues directly attributable to a previously sustained posterior subluxation.

• Ensure documentation clearly states "sequela" or indicates a chronic condition resulting from a past injury.
• Verify the laterality is explicitly documented as "right knee."
• Do not use for acute or initial encounters of a subluxation; this code is specifically for residual effects.
