Displ oblique fx shaft of l tibia, 7thM

This code signifies a specific type of left tibia shaft fracture where the break is angled (oblique) and the bone fragments are not properly aligned (displaced). Importantly, it indicates that the fracture is an open fracture of Type I or II, meaning there's a wound communicating with the fracture site, and that the bone has failed to heal after an initial treatment, leading to a nonunion.

Use this code for follow-up encounters when a patient with a previously diagnosed displaced oblique open fracture (Type I or II) of the left tibial shaft is being treated for a confirmed nonunion. This applies when the patient is receiving ongoing care, such as surgical intervention for the nonunion or monitoring of the nonunion's progress.

• Ensure documentation clearly specifies "displaced," "oblique," "shaft," "left tibia," "open fracture type I or II," and "nonunion."
• This code is for subsequent encounters; an initial encounter for the acute fracture would use a different code.
• Always review the operative report or physician notes to confirm the type of open fracture (Gustilo-Anderson classification) and the presence of nonunion.
