Smith's fx r radius, subs for opn fx type 3A/B/C w nonunion

This code signifies a Smith's fracture of the right radius that has failed to heal properly, specifically an open fracture of severe type (IIIA, IIIB, or IIIC). It indicates that the patient is receiving ongoing care for this nonunion, rather than initial treatment.

Apply this code when documenting follow-up care for a patient with a previously diagnosed open Smith's fracture of the right radius that has progressed to a nonunion. This includes scenarios where the patient is undergoing further surgical intervention, cast changes, or other treatments aimed at promoting healing or managing complications of the nonunion.

• Ensure documentation clearly specifies "nonunion" and the open fracture type (IIIA, IIIB, or IIIC).
• Verify this is a subsequent encounter, not the initial treatment for the fracture.
• Confirm the fracture is specifically a Smith's fracture of the right radius.
