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

This code signifies a chronic or late effect of an incomplete dislocation of the tibia's upper end, specifically on the inner side of the knee joint. It indicates that the tibia has partially slipped out of alignment with the femur, affecting an unspecified knee, and the condition is no longer acute but rather a lingering consequence of an earlier injury.

Apply this code when documenting a patient presenting with ongoing symptoms or complications directly attributable to a past medial subluxation of the proximal tibia. This is appropriate for follow-up encounters where the initial injury has resolved, but the patient continues to experience issues related to the previous subluxation, such as instability or pain.

• Ensure documentation clearly states the condition is a "sequela" or "late effect" of a previous injury, not an acute event.
• This code is for an unspecified knee; if the laterality (left or right) is known, a more specific code should be used.
• Always code any associated pain or functional limitations separately, if documented.
