Nondisp seg fx shaft of rad, r arm, 7thN

This code signifies a segmental fracture of the shaft of the right radius that is not displaced. The fracture was initially an open fracture of type IIIA, IIIB, or IIIC, and the patient is now in a subsequent encounter where the fracture has failed to heal, resulting in a nonunion.

Apply this code for follow-up encounters of patients with a previously diagnosed open segmental right radial shaft fracture (Gustilo-Anderson type IIIA, IIIB, or IIIC) that has not achieved bony union. This is appropriate when the physician documents the nonunion of the nondisplaced segmental fracture.

• Ensure documentation clearly specifies "nonunion" and the "segmental" nature of the fracture.
• Verify the initial open fracture type (IIIA, IIIB, or IIIC) was documented, as this is a key component of the code.
• Confirm the encounter is for follow-up care related to the nonunion, not the initial treatment.
