Displ spiral fx shaft of ulna, r arm, 7thN

This code describes a right ulna shaft fracture, specifically a displaced spiral type, that has failed to heal properly (nonunion). It indicates that the initial injury was an open fracture classified as Type IIIA, IIIB, or IIIC, and the patient is now presenting for follow-up care related to this nonunion.

Use this code for patients presenting for ongoing management of a previously treated, but unhealed, displaced spiral fracture of the right ulna shaft. This is applicable when the original injury was a severe open fracture (Gustilo-Anderson Type IIIA, IIIB, or IIIC) and the current encounter addresses the nonunion complication.

• Ensure documentation clearly specifies "nonunion" and the "subsequent encounter" for this specific fracture.
• Verify the original injury was an open fracture of Gustilo-Anderson Type IIIA, IIIB, or IIIC.
• Confirm the fracture is of the right ulna shaft and is a displaced spiral type.
