Nondisp commnt fx shaft of l tibia, 7thN

This code describes a comminuted fracture of the shaft of the left tibia that is not displaced, meaning the bone fragments are still in their anatomical alignment. It specifically indicates a subsequent encounter for an open fracture classified as Type IIIA, IIIB, or IIIC, which has progressed to nonunion. Nonunion signifies a failure of the bone to heal after a reasonable period.

Use this code for follow-up visits or hospitalizations where a patient is being treated for a previously diagnosed open comminuted left tibial shaft fracture (Type IIIA, IIIB, or IIIC) that has failed to unite. This would include scenarios such as surgical intervention for nonunion, cast changes, or wound care related to the nonunion of the open fracture.

• Ensure documentation clearly specifies "nondisplaced" and "comminuted" for the fracture type.
• Verify the encounter is "subsequent" and that the original injury was an "open fracture type IIIA, IIIB, or IIIC."
• Confirm the presence of "nonunion" as the current complication being addressed.
