In simple words: This surgery fixes a broken bone in the forearm (radius or ulna) that hasn't healed correctly. The doctor opens the area, removes the misaligned bone, and uses a bone graft from another part of your body to help it heal properly. Afterward, your arm is put in a splint.

This procedure addresses a nonunion or malunion deformity in the radius or ulna of the forearm. The surgeon corrects the improperly healed bone by surgically exposing the affected area, removing the irregular bone, and bridging the gap with a bone graft, often taken from the patient's iliac crest. The repaired site is then stabilized, typically with a splint, to promote proper healing.

Example 1: A patient with a nonunion of the radius following a fracture, where the bone has not healed, undergoes open reduction internal fixation with autograft using 25405. , A patient with a malunion of the ulna, where the bone has healed in an incorrect position, requires surgical correction with autograft using 25405., A patient with a previous radius fracture experiences pain due to nonunion. An autograft procedure (25405) is performed to promote bone healing.

Documentation should include details about the nonunion or malunion (e.g., location, type), operative report detailing the procedure including type and source of the autograft, and post-operative care plan.
