Displ oblique fx shaft of unsp tibia, 7thM

This code describes a situation where a patient has a displaced fracture of the shaft of the tibia, specifically an oblique type, that was initially an open fracture (Type I or II). The current encounter is for the ongoing management of this fracture, which has failed to heal properly, resulting in a nonunion.

Use this code for follow-up encounters when a patient with a previously diagnosed open oblique tibial shaft fracture (Type I or II) is experiencing nonunion. This typically involves continued treatment, such as further surgical intervention (e.g., bone grafting, revision fixation) or extended conservative management, due to the lack of bone healing.

• Ensure documentation clearly specifies "nonunion" and the "subsequent encounter" status.
• Verify the original fracture was an "open fracture type I or II" and the fracture type was "oblique" and "displaced."
• Always code additional external cause and place of occurrence codes if applicable for the initial injury.
