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

This code describes a long-term consequence or late effect of a posterior subluxation (partial dislocation) of the proximal tibia in the left knee. This indicates that the initial injury has resolved, but the patient continues to experience residual symptoms or conditions directly related to the previous subluxation.

Use this code when documenting a patient presenting with chronic pain, instability, limited range of motion, or other persistent issues in the left knee, where these symptoms are directly attributed to a past posterior subluxation of the proximal tibia. This applies to follow-up encounters for conditions that developed as a result of the original injury, even if the subluxation itself is no longer acutely present.

• Always sequence this sequela code after the code for the specific residual condition being treated (e.g., chronic pain, osteoarthritis).
• Ensure documentation clearly links the current symptoms or condition to the historical posterior subluxation of the left proximal tibia.
• Do not use for acute or initial encounters of a posterior subluxation; reserve for late effects.
