Displ commnt fx shaft of rad, r arm, 7thN

This code signifies a complex, displaced comminuted fracture of the shaft of the right radius that has failed to heal properly (nonunion). It specifically indicates that the initial injury was an open fracture of a severe type (IIIA, IIIB, or IIIC), and the patient is now being seen for follow-up care related to this ongoing healing complication.

Apply this code when documenting a subsequent encounter for a patient with a previously diagnosed right radial shaft fracture that was initially open and is now complicated by nonunion. This would include scenarios where the patient is undergoing further treatment, evaluation, or management for the unhealed fracture.

• Ensure documentation clearly specifies "nonunion" and the "subsequent encounter" for the fracture.
• Verify the initial fracture was indeed an open fracture of type IIIA, IIIB, or IIIC.
• Confirm the fracture is of the right radius shaft and is comminuted and displaced.
