Nondisp spiral fx shaft of unsp femr, 7thN

This code describes a non-displaced fracture that spirals around the shaft of an unspecified femur, which has failed to heal properly (nonunion). This specific instance is being treated during a subsequent encounter for an open fracture classified as type IIIA, IIIB, or IIIC.

Use this code when documenting follow-up care for a patient with a previously treated open spiral fracture of the femoral shaft that has not united. This applies when the original open fracture was severe (Gustilo-Anderson type IIIA, IIIB, or IIIC) and the current encounter addresses the ongoing nonunion.

• Ensure documentation clearly states "nonunion" and specifies the original open fracture type (IIIA, IIIB, or IIIC).
• Verify the fracture is explicitly described as "nondisplaced" and "spiral" of the femoral shaft.
• This code is for subsequent encounters; an initial encounter would use a different code.
