Oth fx shaft of unsp fibula, 7thM

This code signifies a non-healing fracture of the shaft of an unspecified fibula, which was initially an open fracture (Type I or II). The "subsequent encounter" indicates that the patient is receiving follow-up care for this specific injury after the initial treatment phase. Nonunion implies that the bone has failed to heal completely after a reasonable period.

Apply this code when documenting ongoing treatment for a patient with a previously diagnosed open fibular shaft fracture that has not united. This would include follow-up appointments, imaging studies to assess healing progress, or preparation for further surgical intervention due to the nonunion. It is appropriate for encounters where the focus is on managing the nonunion of the original open fracture.

• Ensure documentation clearly specifies "nonunion" and the original fracture was "open type I or II."
• Verify the encounter is for follow-up care, not the initial treatment of the fracture.
• This code requires a seventh character "M" for subsequent encounter for open fracture type I or II with nonunion.
