Nondisp oblique fx shaft of r ulna, 7thM

This code signifies a previously diagnosed oblique fracture of the shaft of the right ulna that was initially an open fracture (Type I or II), and is now being treated for a nonunion. Nonunion indicates that the bone fragments have failed to heal together after a sufficient period.

This code is appropriate for follow-up encounters where a patient with a history of an open right ulnar shaft fracture (oblique, nondisplaced) is presenting for ongoing management of a nonunion. This includes visits for assessment, treatment planning, or intervention related to the delayed or failed healing of the fracture.

• Ensure documentation clearly states "nonunion" and specifies the "subsequent encounter" for the fracture.
• Verify the initial fracture was an "open fracture type I or II" as this is a specific inclusion criterion.
• Do not use this code for initial treatment or routine follow-up of a healing fracture; it is specifically for nonunion.
