Oth fx shaft of right tibia, subs for clos fx w nonunion

This code signifies a non-healing fracture of the shaft of the right tibia, specifically an "other" type of fracture beyond the more common spiral, transverse, or oblique. The patient is in a subsequent phase of care, and the fracture has not united, despite the skin remaining intact over the injury site.

Apply this code for follow-up encounters where a patient with a previously diagnosed right tibial shaft fracture (not spiral, transverse, or oblique) is found to have nonunion. This is appropriate when the fracture is being managed conservatively (closed treatment) and the nonunion is documented by the provider.

• Ensure documentation explicitly states "nonunion" for a right tibial shaft fracture.
• Verify the fracture type is not spiral, transverse, or oblique; otherwise, a more specific code may apply.
• Confirm the encounter is for subsequent care and the fracture is being treated as closed.
