Nondisp fx of coronoid pro of r ulna, 7thN

This code describes a situation where a patient has a fracture of the coronoid process in their right ulna that was initially nondisplaced, but is now complicated by a nonunion. Furthermore, the original injury was an open fracture classified as type IIIA, IIIB, or IIIC, indicating significant soft tissue damage and contamination. This code is used during a subsequent encounter for ongoing treatment of this specific fracture and its complications.

Use this code when a patient presents for follow-up care of a previously diagnosed nondisplaced coronoid process fracture of the right ulna. The key conditions for using this code are the presence of a documented nonunion and the original injury being an open fracture of Gustilo type IIIA, IIIB, or IIIC. This code would be appropriate for visits related to surgical intervention for nonunion, cast changes, or monitoring of healing progress.

• Ensure documentation clearly specifies "nondisplaced" for the initial fracture and "nonunion" for the current status.
• Verify the original fracture was an "open fracture" and the Gustilo classification (IIIA, IIIB, or IIIC) is documented.
• This code is for "subsequent encounters" only; do not use for the initial treatment of the fracture.
