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

This code signifies a nonunion of a displaced spiral fracture located in the shaft of the radius, where the specific arm (left or right) is not documented. The fracture was an open type IIIA, IIIB, or IIIC, indicating significant soft tissue damage and contamination, and the patient is presenting for follow-up care related to the nonunion.

Apply this code when a patient is seen for ongoing management of a previously treated open spiral radial shaft fracture that has failed to heal (nonunion). This is appropriate for subsequent encounters where the initial injury was an open fracture with extensive soft tissue involvement, and the laterality of the arm is unspecified in the medical record.

• Ensure documentation clearly states "nonunion" and specifies the fracture as "spiral" and "displaced" in the radial shaft.
• Verify the original fracture was an open type IIIA, IIIB, or IIIC.
• Only use this code when the affected arm is not specified in the clinical notes.
