Nondisp seg fx shaft of l tibia, subs for clos fx w nonunion

This code describes a fracture involving multiple segments of the shaft of the left tibia that has not shifted from its anatomical position. It specifically indicates that the fracture has failed to heal properly after an initial treatment, and the patient is presenting for follow-up care for this ununited closed fracture.

This code is appropriate for documenting ongoing management of a patient with a left tibial shaft fracture that has not healed, where the fracture fragments remain aligned. It should be used during subsequent visits for nonunion treatment, such as surgical intervention (e.g., bone grafting, revision fixation) or conservative management.

• Ensure documentation clearly specifies "nonunion" and "subsequent encounter" for accurate code assignment.
• Verify the fracture is of the "shaft" and "left tibia," and that it is "nondisplaced" and "segmental."
• Do not use this code for initial encounters or for fractures that have healed or are in the process of routine healing.
