Nondisp oblique fx shaft of unsp fibula, 7thN

This code signifies a non-displaced fracture of the fibula shaft, characterized by an oblique break, that is currently in a state of nonunion. It specifically applies when the initial injury was an open fracture of type IIIA, IIIB, or IIIC, and the patient is presenting for follow-up care related to this ongoing healing complication.

Use this code for patients presenting for subsequent treatment of a non-displaced oblique fibular shaft fracture that has failed to heal (nonunion). This is appropriate when the original injury was a severe open fracture (Gustilo-Anderson types IIIA, IIIB, or IIIC) and the patient is receiving ongoing management for the nonunion.

• Ensure documentation clearly specifies "nonunion" and the "subsequent encounter" for the fracture.
• Verify the original fracture was an open fracture, specifically type IIIA, IIIB, or IIIC, as this impacts the seventh character.
• Confirm the fracture is of the fibula shaft and is described as "nondisplaced oblique."
