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

This code signifies a segmental fracture of the radial shaft that has not been displaced, occurring in an unspecified arm. It specifically indicates a subsequent encounter for an open fracture classified as type IIIA, IIIB, or IIIC, where the fracture has failed to heal properly (nonunion).

This code is appropriate for follow-up visits or admissions where a patient is being treated for a previously diagnosed open segmental radial shaft fracture (types IIIA, IIIB, or IIIC) that has developed nonunion. It should be used when the fracture is still present and not healing as expected, requiring ongoing medical management.

• Ensure documentation clearly specifies "segmental" and "nondisplaced" for the radial shaft fracture.
• Verify the original open fracture was classified as type IIIA, IIIB, or IIIC, and that nonunion is explicitly documented.
• Confirm this is a subsequent encounter for the fracture, not the initial treatment.
