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

This code signifies a chronic or late-stage consequence of a previous injury to the left knee, specifically involving a partial dislocation of the upper part of the shin bone (tibia) towards the outside of the knee joint. This subluxation is not an acute event but rather a persistent issue or complication arising from an earlier trauma.

Apply this code when documentation indicates a patient is experiencing ongoing symptoms or complications directly attributable to a past lateral subluxation of the proximal tibia in the left knee. This includes conditions like chronic instability, pain, or functional limitations that are a direct result of the original injury. It should be used for follow-up care or when the sequela itself is the primary reason for the encounter, long after the initial acute injury has healed.

• Ensure documentation clearly states "sequela" or indicates a chronic condition resulting from a past injury.
• Do not use this code for acute or initial encounters for a subluxation; those require acute injury codes.
• Always review the patient's history to confirm the subluxation occurred previously and the current encounter addresses its long-term effects.
