Disp fx of base of nk of unsp femr, 7thK

This code signifies a non-healing fracture located at the base of the femoral neck, which is displaced from its normal anatomical alignment. The patient is in a subsequent phase of care, specifically for a closed fracture that has failed to unite.

This code is appropriate for patients presenting for follow-up care of a previously diagnosed and treated closed fracture of the femoral neck base, where imaging or clinical assessment confirms nonunion. It would be used when the patient is undergoing further management, such as revision surgery, bone grafting, or prolonged immobilization due to the nonunion.

• Ensure documentation clearly states "nonunion" and specifies the "base of neck" as the fracture site.
• Verify the encounter is "subsequent" and the initial fracture was "closed."
• Do not use for initial treatment or for malunion; nonunion is a distinct complication.
