Lateral disloc of proximal end of tibia, unsp knee, sequela

This code signifies a past injury involving the lateral displacement of the upper portion of the shin bone relative to the thigh bone, affecting an unspecified knee. It indicates that the patient is currently experiencing a residual condition or complication directly resulting from this previous dislocation.

Apply this code when documentation clearly indicates a long-term effect or complication stemming from a prior lateral dislocation of the proximal tibia. This is appropriate for follow-up encounters where the original injury has healed, but the patient continues to experience issues such as chronic instability, pain, or functional limitations directly attributable to the past dislocation.

• Ensure the documentation explicitly states a "sequela" or a residual condition from a past lateral proximal tibia dislocation.
• This code is for an unspecified knee; if the laterality (right or left) is known, a more specific code should be used.
• Always code the specific sequela (e.g., chronic pain, instability) in addition to this sequela code.
