Nondisp transverse fx shaft of unsp tibia, 7thM

This code describes a transverse fracture in the shaft of an unspecified tibia that has not healed properly (nonunion) and is currently being managed. The initial injury was an open fracture, classified as Type I or II, meaning there was a break in the skin communicating with the fracture site. The fracture fragments are still in their normal anatomical alignment.

Use this code for follow-up encounters for a patient with a previously diagnosed nondisplaced transverse tibial shaft fracture that was initially an open Type I or II injury and is now complicated by nonunion. This applies when the patient is receiving ongoing treatment for the nonunion, such as cast changes, wound care, or preparation for revision surgery.

• Ensure documentation clearly specifies "nonunion" and that the initial fracture was an "open Type I or II."
• Verify the fracture is nondisplaced and located in the shaft of the tibia.
• This code is for subsequent encounters; use the appropriate initial encounter code for the acute injury.
