Nondisp spiral fx shaft of unsp tibia, 7thM

This code signifies a spiral fracture of the main shaft of the tibia that has not shifted out of alignment. It specifically indicates that the fracture was initially an open fracture (meaning the skin was broken) of either Type I or Type II, and the bone is now failing to heal properly.

This code is appropriate for follow-up encounters where a patient with a previously diagnosed nondisplaced spiral open fracture (Type I or II) of the tibial shaft is being treated for a confirmed nonunion. This would apply when the physician documents ongoing management of the fracture due to delayed or failed healing.

• Confirm documentation explicitly states "nondisplaced spiral fracture of shaft of tibia" and "nonunion."
• Verify the initial injury was an "open fracture type I or II" as this is crucial for code selection.
• Ensure the encounter is "subsequent" and not for the initial treatment of the fracture.
