Unsp fx shaft of l tibia, 7thN

This code describes a situation where a patient has an unconfirmed fracture location within the shaft of their left tibia, and they are presenting for follow-up care related to a previously diagnosed open fracture. The open fracture was specifically classified as a severe Type IIIA, IIIB, or IIIC, and the current concern is that the bone is not healing properly (nonunion).

Use this code for subsequent encounters when a patient with a prior open left tibial shaft fracture (Type IIIA, IIIB, or IIIC) is being treated for nonunion, and the exact location of the fracture within the shaft was not specified in the initial diagnosis. This applies to ongoing management, surgical planning for nonunion, or evaluation of healing progress.

• Ensure documentation clearly indicates a "subsequent encounter" and "nonunion" for an open fracture type IIIA, IIIB, or IIIC.
• Confirm the fracture is of the left tibia shaft and that the initial fracture site within the shaft was unspecified.
• Do not use for initial encounters or for fractures that are healing normally.
