Displ transverse fx shaft of r ulna, 7thN

This code signifies a non-healing fracture of the shaft of the right ulna, specifically a transverse break that has shifted out of alignment. It indicates that the patient is in a later phase of treatment for a severe open fracture (Type IIIA, IIIB, or IIIC) where the bone has failed to unite.

Apply this code when documenting ongoing management of a right ulnar shaft fracture that was initially an open fracture of significant severity, and current imaging or clinical assessment confirms nonunion. This is appropriate for follow-up visits, surgical interventions for nonunion, or rehabilitation related to the persistent fracture.

• Ensure documentation clearly specifies "nonunion" and the "subsequent encounter" for the open fracture type.
• Verify the fracture is indeed transverse and located in the shaft of the right ulna.
• Always sequence this code after any acute treatment codes or codes for the initial injury, if applicable.
