Unsp fx head of right femur, subs for clos fx w nonunion

This code indicates a fracture of the head of the right femur where the specific type of fracture (e.g., displaced, nondisplaced) is not documented. Crucially, it signifies that the fracture has failed to heal properly (nonunion) and the patient is presenting for follow-up care or treatment of this persistent issue, with the skin over the fracture remaining intact.

Apply this code when a patient with a previously diagnosed, unspecified closed fracture of the right femoral head is seen for ongoing management of a documented nonunion. This includes visits for evaluation of nonunion, planning for surgical intervention to address nonunion, or conservative management of the nonunion.

• Ensure documentation clearly states "nonunion" and specifies the "subsequent encounter" for the closed fracture.
• Verify laterality (right femur) and the specific anatomical site (femoral head).
• Do not use for initial fracture treatment or for malunion, which is a different complication.
