Medial sublux of proximal end of tibia, left knee, sequela

This code signifies a persistent or long-term issue stemming from a prior incomplete dislocation of the medial aspect of the proximal tibia in the left knee. It indicates that the tibia is still partially displaced relative to the femur on the inner side of the joint, leading to ongoing symptoms or functional limitations. This is not an acute injury but rather a lasting consequence.

Use this code for patients presenting with chronic pain, instability, or functional impairment in the left knee, where imaging or clinical assessment confirms a residual medial subluxation of the proximal tibia. This applies when the initial injury has resolved, but the subluxation remains as a sequela. It is appropriate for follow-up visits addressing these long-term complications.

• Always ensure documentation clearly states "sequela" or indicates a chronic, residual condition from a previous injury.
• Verify laterality (left knee) is explicitly documented to support code selection.
• Distinguish from acute subluxations, which would use different codes without the "S" seventh character.
