Displ transverse fx shaft of unsp femr, 7thN

This code signifies a nonunion of a displaced fracture in the mid-portion of the femur, which was initially an open fracture of severe type (IIIA, IIIB, or IIIC). Nonunion indicates that the bone has failed to heal completely after a significant period. This code is used during follow-up care for such a complex injury.

This code is appropriate for subsequent encounters when a patient with a previously diagnosed open, displaced transverse femoral shaft fracture (types IIIA, IIIB, or IIIC) is being treated for a confirmed nonunion. This would include situations where surgical intervention for nonunion is being planned or performed, or during ongoing management of the unhealed fracture.

• Ensure documentation clearly specifies "nonunion" and the initial fracture was an open fracture type IIIA, IIIB, or IIIC.
• Verify the fracture location is the shaft of the femur and the displacement is noted.
• This code is for subsequent encounters; an initial encounter for the nonunion would typically use a different code.
