Disp fx of base of nk of l femr, subs for clos fx w nonunion

This code signifies a situation where a patient has a previously diagnosed fracture at the base of the neck of their left femur, which is displaced, and the fracture has failed to heal properly (nonunion). This particular encounter is for ongoing management of this unhealed closed fracture.

Apply this code when a patient presents for follow-up care, evaluation, or treatment of a nonunion of a displaced left femoral neck fracture. This includes scenarios where surgical intervention for the nonunion is being planned or has recently been performed, or when conservative management of the nonunion is ongoing.

• Ensure documentation clearly states "nonunion" and specifies the "subsequent encounter" for the closed fracture.
• Verify the fracture location as the "base of the neck" of the femur and laterality as "left."
• Do not use this code for initial treatment or for malunion; a specific nonunion code is required.
