Bent bone of left radius, subs for clos fx w nonunion

This code signifies a left radial shaft fracture that has healed with a noticeable bend or angulation, and where the bone fragments have failed to unite after initial treatment. It indicates a persistent nonunion of the fracture, despite the skin remaining intact over the injury site.

Apply this code for follow-up encounters of a patient with a previously treated closed fracture of the left radial shaft that has resulted in a bent bone and is confirmed to be a nonunion. This is appropriate when the patient is receiving ongoing care for the nonunion, such as evaluation for surgical intervention or conservative management.

• Ensure documentation clearly states "bent bone" or "angulated" and "nonunion" for the left radius.
• Verify the encounter is for subsequent care, not the initial treatment of the fracture.
• Confirm the fracture was initially closed, meaning no open wound communicated with the fracture site.
