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

This code signifies a specific type of fracture in the left radius, where the bone is broken in a spiral pattern along its shaft and the fragments are no longer aligned. It further specifies that this is an open fracture, classified as Type IIIA, IIIB, or IIIC, meaning there is a wound communicating with the fracture site, and the patient is presenting for follow-up care due to the fracture failing to heal (nonunion).

This code is appropriate for subsequent encounters when a patient with a previously diagnosed displaced spiral open fracture (Type IIIA, IIIB, or IIIC) of the left radial shaft is being treated for nonunion. This would include follow-up appointments, imaging studies, or surgical interventions specifically addressing the nonunion of this particular fracture.

• Ensure documentation clearly specifies "left arm" and "nonunion" for this specific fracture type.
• Verify the open fracture type (IIIA, IIIB, or IIIC) is documented, as this impacts code selection.
• Confirm this is a subsequent encounter, not the initial treatment for the fracture.
