Repair of Nonunion Monteggia Fracture Dislocation
A patient with a prior left elbow injury now presents with hardware failure and nonunion of a Monteggia (fracture of the proximal ulna/dislocation of the radial head) fracture with infection and radiocapitellar instability. The patient presents for repair which includes open reduction and internal fixation (ORIF) of the proximal ulna with reduction of the anterior radial head dislocation and additional procedures. The previous incision was utilized and dissection was carried down through the subcutaneous tissue reaching the plates and broken screws to remove them in their entirety. Direct visualization reveals the distal fracture was healing well; therefore, this area was left alone. Attention was turned to the nonunion, debriding necrotic bone and tissue from the ulna. At this point a canal was prepared via drilling and a deep bone biopsy was obtained. An antibiotic cement spacer was formed using 40 g of PMMA, 2 g of vancomycin, and 1.2 g of tobramycin. Once the cement hardened, the spacer and a pin were placed into the intramedullary space fixating the ulna and reducing the radial head back into the capitellum. An additional antibiotic spacer was formed and placed into the space around the pin and into the 2.5 cm defect. Once the cement hardened and the incision closed, x-rays were taken to confirm reduction of the anterior radial head and ulna fixation. What are the correct codes for facility reporting for repair of the nonunion of the proximal ulna with reduction of the anterior radial head dislocation? ...

Article Overview
This premium coding article discusses surgical management of a complicated Monteggia fracture nonunion affecting the elbow, including hardware removal, fixation, debridement, bone biopsy, and placement of an antibiotic cement spacer. It is intended for coders, billers, and orthopedic surgery coding professionals who need to understand the scope of the operative report and the related procedure coding considerations.
Why This Topic Matters
Complex fracture nonunion cases often involve multiple overlapping procedures and extensive operative detail. Understanding the scope of the surgery helps support accurate coding review for orthopedic trauma and infection-related reconstruction cases.
