Oth fx shaft of unsp tibia, 7thM

This code signifies a non-healing fracture of the main part of the shin bone (tibia) that was initially an open fracture (skin broken) of either Type I or Type II severity. The patient is currently in a phase of treatment following the initial injury, and the fracture has failed to unite.

Use this code for a patient presenting for follow-up care of a tibial shaft fracture that was initially open (Type I or II) and is now complicated by nonunion. This applies when the patient is receiving ongoing treatment, such as cast changes, physical therapy, or surgical planning for the nonunion.

• Ensure documentation specifies an open fracture (Type I or II) and explicitly states nonunion of the tibial shaft.
• Verify this is a subsequent encounter, not the initial treatment for the fracture.
• Always sequence this code after the primary reason for the encounter if it's not the main focus of the visit.
