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

This code describes a left arm radius shaft fracture that is spiral in nature and has not been displaced. It specifically indicates that the fracture is an open fracture of type IIIA, IIIB, or IIIC, and that the bone has failed to heal properly, resulting in nonunion. This code is used for encounters following the initial treatment of the fracture.

Use this code when a patient presents for follow-up care of a previously treated open spiral fracture of the shaft of the left radius, and documentation confirms nonunion of the fracture. This applies to situations where the fracture was initially classified as an open type IIIA, IIIB, or IIIC injury. It is appropriate for subsequent visits related to managing the nonunion.

• Ensure documentation clearly specifies "nonunion" and the open fracture type (IIIA, IIIB, or IIIC).
• Verify laterality (left arm) and the specific bone involved (radius shaft).
• This is a subsequent encounter code; do not use for the initial treatment of the fracture.
