Nondisp commnt fx shaft of rad, l arm, 7thN

This code describes a situation where a patient has a comminuted fracture of the shaft of the left radius that was initially an open fracture (Type IIIA, IIIB, or IIIC), and despite previous treatment, the bone has failed to heal (nonunion). The fracture fragments are still in their anatomical position, meaning they have not shifted out of alignment.

Use this code for follow-up encounters for a patient with a previously treated open comminuted left radial shaft fracture where imaging and clinical assessment confirm nonunion. This applies when the fracture was initially classified as a severe open fracture (Gustilo-Anderson Type IIIA, IIIB, or IIIC) and the fragments remain nondisplaced.

• Ensure documentation clearly specifies "nondisplaced" and "comminuted" for the radial shaft fracture.
• Verify the initial injury was an open fracture of Gustilo-Anderson Type IIIA, IIIB, or IIIC.
• Confirm the encounter is for subsequent care of a diagnosed nonunion, not initial treatment or routine follow-up of a healing fracture.
