Unsp fx upr end unsp tibia, 7thN

This code describes a situation where the upper part of the shin bone (tibia) has an open fracture, meaning the skin was broken, and the specific type of fracture is not documented. The fracture is complicated by a nonunion, indicating that the bone is failing to heal, and the patient is receiving ongoing treatment for this issue. This specific nonunion is associated with a severe open fracture (Type IIIA, IIIB, or IIIC).

This code is appropriate for subsequent encounters when a patient is being treated for a nonunion of an unspecified open fracture of the proximal tibia. This includes follow-up visits, cast changes, or other interventions aimed at promoting healing of the nonunion. It should be used when the initial fracture type (e.g., transverse, oblique) was not specified in the medical record, but the open nature and severity (Type IIIA, IIIB, or IIIC) are documented.

• Ensure documentation clearly states "nonunion" and specifies the open fracture type as IIIA, IIIB, or IIIC.
• This code is for subsequent encounters; an initial encounter code would be used for the first treatment.
• Verify that the fracture location is the "upper end of the tibia" and that the specific fracture type is indeed "unspecified."
