Unsp fx low end unsp ulna, 7thJ

This code signifies an unspecified fracture of the lower portion of the ulna that was initially an open fracture of type IIIA, IIIB, or IIIC. The patient is currently in a subsequent encounter for this injury, and the healing process is delayed. This indicates that the bone is not mending at the expected rate.

This code is appropriate for follow-up visits where a patient is being monitored for an open distal ulnar fracture (initially classified as IIIA, IIIB, or IIIC) that is not healing as anticipated. It would be used when the specific type of fracture at the lower end of the ulna is not documented, but the delayed healing of the initial open injury is the focus of the encounter.

• Ensure documentation clearly states "delayed healing" for an open fracture type IIIA, IIIB, or IIIC.
• This code is for subsequent encounters; an initial encounter code would have been used for the acute injury.
• Verify that the fracture location is specifically the lower end of the ulna, even if unspecified further.
