Nondisp spiral fx shaft of l fibula, 7thM

This code describes a specific type of fracture involving the shaft of the left fibula, characterized by a spiral pattern and no displacement of the bone fragments. It indicates that the fracture was initially an open fracture of either Type I or Type II, and the patient is now presenting for follow-up care due to a failure of the bone to heal properly (nonunion).

This code is appropriate for subsequent encounters when a patient with a previously diagnosed open spiral fracture of the left fibular shaft (Type I or II) is being treated for nonunion. This includes situations where surgical intervention for nonunion is being planned or performed, or during ongoing conservative management for the delayed healing.

• Ensure documentation clearly specifies "nondisplaced," "spiral fracture of shaft of left fibula," and "open fracture type I or II" for the initial injury.
• Confirm the encounter is for subsequent care related to the nonunion, not the initial treatment of the fracture.
• Always sequence this code with an external cause code (e.g., V00-Y99) to describe the circumstances of the injury, if known and applicable.
