Oth fx shaft of r tibia, subs for opn fx type I/2 w nonunion

This code describes a situation where a patient has a fracture in the shaft of their right tibia that is not healing properly (nonunion). This specific fracture was initially an open fracture, classified as Type I or Type II, and the patient is now receiving follow-up care for this ongoing issue.

Use this code for subsequent encounters when a patient presents with a documented nonunion of an open Type I or Type II fracture of the shaft of the right tibia. This applies when the patient is receiving ongoing treatment, evaluation, or management for the persistent non-healing of this specific fracture.

• Ensure documentation clearly specifies "nonunion" and the initial open fracture type (I or II).
• Verify the fracture location is the shaft of the right tibia, not the proximal or distal ends.
• This code is for subsequent encounters; an initial encounter would use a different code.
