Nondisp commnt fx shaft of unsp tibia, 7thM

This code describes a situation where a patient has a comminuted fracture (broken into multiple pieces) in the shaft of their tibia, but the bone fragments are still in their normal anatomical position (nondisplaced). This specific encounter is for ongoing treatment of an open fracture (where the bone broke through the skin) classified as Type I or II, and the fracture has not healed as expected (nonunion).

This code is appropriate for follow-up visits where a patient is being treated for a previously diagnosed open comminuted tibial shaft fracture (Type I or II) that is failing to unite. It would be used when the physician is assessing the nonunion, planning further interventions, or managing complications related to the nonunion in an open fracture setting.

• Ensure documentation clearly specifies "nondisplaced," "comminuted," and "shaft" of the tibia.
• Verify the encounter is for an "open fracture type I or II" and explicitly states "nonunion."
• Do not use for initial fracture treatment or for malunion (healed in a deformed position).
