Displ seg fx shaft of r fibula, 7thN

This code describes a specific type of fracture involving the shaft of the right fibula, characterized by multiple fracture fragments that are out of alignment. It indicates that the fracture is open, meaning the bone has broken through the skin, and is a severe type (IIIA, IIIB, or IIIC) according to the Gustilo-Anderson classification. Furthermore, this code is used when the fracture has failed to heal properly after an initial treatment, and the patient is receiving ongoing care for this nonunion.

This code is appropriate for subsequent encounters when a patient with a previously treated open, displaced segmental fracture of the right fibula shaft (Gustilo-Anderson type IIIA, IIIB, or IIIC) presents for follow-up care, evaluation, or treatment of a confirmed nonunion. This includes scenarios where the patient is undergoing further surgical intervention, cast changes, or other management strategies specifically for the nonunion.

• Ensure documentation clearly states "nonunion" and specifies the Gustilo-Anderson classification (IIIA, IIIB, or IIIC) for the open fracture.
• Verify that this is a "subsequent encounter" and not the initial treatment for the fracture.
• Confirm the fracture is of the fibula shaft and is segmental and displaced.
