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

This code describes a spiral fracture of the shaft of the radius that is not displaced, located in an unspecified arm. The key aspect is that this is a subsequent encounter for an open fracture of type IIIA, IIIB, or IIIC, and the fracture has failed to heal properly, resulting in a nonunion.

Use this code when documenting follow-up care for a patient with a previously treated open spiral fracture of the radial shaft (types IIIA, IIIB, or IIIC) that has not united. This applies when the fracture itself is nondisplaced at the time of this subsequent encounter. It is appropriate for ongoing management of the nonunion.

• Ensure documentation clearly specifies "unspecified arm" if laterality is not known or recorded.
• Confirm the original fracture was an open fracture of type IIIA, IIIB, or IIIC.
• Verify that the current encounter is for a nonunion, indicating failed healing.
