Nondisp seg fx shaft of l tibia, 7thN

This code signifies a left tibia shaft fracture that is broken into multiple pieces (segmental) and has not shifted from its original position (nondisplaced). The fracture was initially an open fracture (meaning the bone broke through the skin) classified as type IIIA, IIIB, or IIIC, and the bone fragments have failed to heal together after a period of time (nonunion).

This code is appropriate for encounters where a patient is receiving ongoing treatment for a previously diagnosed nondisplaced segmental fracture of the left tibial shaft. The key elements for its use are the initial open nature of the fracture (types IIIA, IIIB, or IIIC) and the current complication of nonunion, indicating a failure of the bone to mend. This would typically be used for follow-up visits, surgical interventions for nonunion, or other management of this specific complication.

• Ensure documentation clearly specifies "nondisplaced" and "segmental" for the left tibia shaft fracture.
• Verify the original open fracture was classified as type IIIA, IIIB, or IIIC, and that nonunion is explicitly documented.
• This code is for subsequent encounters; an initial encounter for this specific fracture and nonunion would use a different code.
