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

This code signifies a chronic or late effect of an incomplete dislocation of the medial aspect of the upper shin bone (tibia) relative to the thigh bone (femur) in the right knee. This condition implies that the joint surfaces are no longer perfectly aligned, but still maintain some contact, and the injury's acute phase has passed.

This code is appropriate for documenting residual symptoms or conditions stemming from a prior medial subluxation of the proximal tibia in the right knee. It should be used when the patient is presenting for treatment of long-term complications, pain, or instability directly attributable to the old injury. Do not use this code for acute injuries.

• Always ensure documentation clearly states "sequela" or "late effect" and specifies the right knee.
• Look for terms like "old injury," "chronic subluxation," or "residual instability" in the medical record.
• Do not use this code if the subluxation is current or acute; instead, use the appropriate acute subluxation code.
