Displ transverse fx shaft of unsp tibia, 7thM

This code describes a transverse fracture of the shaft of the tibia that is displaced and has failed to heal (nonunion). It specifically applies to open fractures initially classified as Type I or II, indicating a less severe open wound.

Use this code for follow-up encounters where a patient with a previously treated open transverse tibial shaft fracture (Type I or II) is now presenting with evidence of nonunion. This typically involves ongoing pain, instability, or radiographic findings confirming the lack of healing.

• Ensure documentation specifies "displaced" and "transverse" fracture of the tibial shaft.
• Confirm the initial injury was an "open fracture type I or II" and the current encounter is for "nonunion."
• This is a subsequent encounter code; do not use for the initial treatment of the fracture.
