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

This code signifies a persistent or late-effect displacement of the upper portion of the right shin bone (tibia) relative to the thigh bone (femur), specifically in a lateral direction, following an initial injury. It indicates that the subluxation itself is no longer an acute event but rather a long-term consequence or complication of a previous trauma to the right knee.

Use this code when documenting a patient presenting with ongoing symptoms or functional limitations directly attributable to a past lateral subluxation of the proximal right tibia. This is appropriate for follow-up visits where the original injury has healed, but the subluxation's residual effects are being addressed. It should be applied when the subluxation is no longer acute but rather a chronic condition or a complication that has developed after the initial injury.

• Always use an additional code to identify the original injury that led to the subluxation, if known.
• Ensure documentation clearly states the "sequela" nature of the subluxation, indicating it's a late effect.
• Verify laterality (right knee) is explicitly documented to support this specific code.
