Unsp fx shaft of l tibia, 7thM

This code indicates a non-healing fracture of the main part of the left shin bone, where the bone broke through the skin (open fracture type I or II). The patient is in a later stage of care, specifically for the complication of nonunion, meaning the fracture has failed to heal properly.

Apply this code when documenting follow-up care for a patient with a previously diagnosed open fracture (Type I or II) of the left tibial shaft that has not united. This is used for subsequent encounters where the nonunion is the primary focus of treatment or evaluation.

• Requires a seventh character of "M" for subsequent encounter for open fracture type I or II with nonunion.
• Ensure documentation clearly specifies "left tibia" and "shaft" as the fracture location.
• Confirm the fracture is explicitly documented as an "open fracture type I or II" and that "nonunion" is present.
