Nondisp fx of lateral condyle of unsp femr, 7thN

This code describes a non-displaced fracture of the outer portion of the lower thigh bone, specifically when the fracture has failed to heal (nonunion). It indicates that the initial injury was an open fracture of a severe type (IIIA, IIIB, or IIIC), and the patient is receiving ongoing care for this unhealed fracture.

Use this code for follow-up encounters where a patient is being treated for a nonunion of a previously diagnosed non-displaced lateral femoral condyle fracture. This applies when the original injury was an open fracture with significant soft tissue damage or contamination, and the bone fragments have not successfully fused.

• Ensure documentation clearly states "nonunion" and specifies the original open fracture type (IIIA, IIIB, or IIIC).
• Verify the fracture is non-displaced and located on the lateral condyle of the femur.
• This code is for subsequent encounters; an initial encounter code would be used for the acute injury.
