Nondisp transverse fx shaft of r tibia, 7thN

This code describes a situation where a patient has a transverse fracture of the shaft of their right tibia that is not displaced, meaning the bone fragments are still in alignment. The fracture is an open fracture, classified as type IIIA, IIIB, or IIIC, indicating significant soft tissue damage and potential contamination. Crucially, this code signifies that the fracture has failed to heal properly, leading to a nonunion, and the patient is receiving ongoing treatment for this complication.

Use this code for patients presenting for follow-up care, surgical intervention, or other treatment related to a previously diagnosed nondisplaced transverse fracture of the right tibial shaft that was an open fracture (Type IIIA, IIIB, or IIIC) and has now been confirmed as a nonunion. This applies when the patient is beyond the initial healing phase and the fracture has not united.

• Ensure documentation clearly specifies "nonunion" and the type of open fracture (IIIA, IIIB, or IIIC).
• Verify laterality (right tibia) and the specific fracture type (transverse shaft, nondisplaced).
• This code is for subsequent encounters; an initial encounter for the acute fracture would use a different code.
