Oth fx of low end r rad, 7thN

This code signifies a complex fracture of the lower part of the right radius, specifically an open fracture classified as type IIIA, IIIB, or IIIC. The "subsequent encounter" indicates that the patient is receiving ongoing care for this injury, and the "nonunion" specifies that the bone fragments have failed to heal together after a typical healing period.

Use this code for follow-up visits where a patient is being treated for a previously diagnosed open fracture of the distal right radius, and the physician documents that the fracture has not united. This applies when the initial open fracture was severe, involving significant soft tissue damage (Gustilo-Anderson types IIIA, IIIB, or IIIC). It would be appropriate for scenarios such as ongoing wound care, assessment for bone grafting, or preparation for revision surgery due to nonunion.

• Ensure documentation clearly specifies "nonunion" and the Gustilo-Anderson classification (IIIA, IIIB, or IIIC) of the original open fracture.
• Verify that this is a subsequent encounter, not the initial treatment for the fracture.
• Confirm the laterality is "right" and the fracture is of the "lower end" of the radius.
