Unsp fx head of unsp femur, subs for clos fx w malunion

This code signifies a follow-up encounter for a previously diagnosed, non-specific fracture of the femoral head, which is now healing improperly (malunion) and was initially a closed injury. The exact location of the fracture on the femoral head is not specified.

Apply this code when a patient presents for ongoing management or evaluation of a closed femoral head fracture that has not healed correctly, and the specific part of the femoral head involved was not documented. This is appropriate for subsequent visits after the initial treatment of the fracture.

• Ensure documentation clearly states "malunion" and that the fracture was "closed."
• Verify that the encounter is for follow-up care, not the initial treatment of the fracture.
• Confirm that the specific location of the fracture on the femoral head is not detailed in the medical record.
