Anterior sublux of proximal end of tibia, unsp knee, sequela

This code signifies a chronic or residual issue stemming from a prior anterior subluxation of the proximal tibia in an unspecified knee. It indicates that the knee joint's alignment, specifically the tibia's relationship to the femur, was previously disrupted in an anterior direction, and the patient is now experiencing long-term effects or complications from that original injury.

Apply this code when documenting the late effects or sequelae of an anterior tibial subluxation that occurred in the past, and the specific knee (left or right) is not documented. This is appropriate for patients presenting with ongoing pain, instability, limited range of motion, or other chronic symptoms directly attributable to the historical subluxation.

• Ensure documentation clearly links the current condition to a previous anterior subluxation of the proximal tibia.
• Only use this code when the laterality of the affected knee is not specified in the medical record.
• Always sequence this sequela code after the primary diagnosis for the current manifestation (e.g., chronic pain, instability).
