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

This code describes a displaced fracture located at the base of the femoral neck, where the specific side (left or right) of the femur is not documented. It indicates that the patient is in a subsequent phase of care for an open fracture, specifically Type I or II, which has failed to heal properly (nonunion).

This code is appropriate for follow-up encounters when a patient with a previously treated open fracture (Type I or II) of the unspecified femoral neck base presents with evidence of nonunion. This would typically involve ongoing management, assessment, or treatment for the unhealed fracture. It should be used when the initial injury was an open fracture, and the nonunion is a complication.

• Ensure documentation clearly states "unspecified femur" and "nonunion" for an open fracture Type I or II.
• Verify that this is a subsequent encounter, not the initial treatment for the fracture.
• Always code the underlying cause of the fracture if known and applicable.
