About 24635: Open treatment of Monteggia fracture-dislocation
Reports operative treatment of a Monteggia injury, combining a proximal ulna fracture with radial head dislocation, when the fracture-dislocation is managed openly.
A Monteggia injury pairs a fracture of the proximal ulna with dislocation of the radial head. An orthopedic surgeon treats it through an open approach, reducing the fracture-dislocation and stabilizing the ulna with fixation when performed. These operations are generally done in a hospital or ambulatory surgery setting; the operative report should establish the injury pattern and describe the reduction and stabilization performed.
Select this code for open operative management of the Monteggia fracture-dislocation, rather than closed treatment of the same injury. The 90-day global period includes the day-before preoperative visit and 90 days of related postoperative care. When multiple procedures are performed in the same session, the highest-valued procedure is paid in full and others at 50%. Bilateral reporting with modifier 50 is paid at 150%. Assistant-at-surgery services may be paid; co-surgeon payment requires supporting documentation, and team surgery is not permitted.

This code addresses open treatment of an elbow dislocation. A proximal ulna fracture with radial head dislocation identifies the Monteggia pattern addressed by 24635.
No office rate
This code is for open treatment of a proximal ulna fracture without the Monteggia fracture-dislocation pattern. The associated radial head dislocation distinguishes 24635.
No office rate
This code treats a radial head or neck fracture openly. A Monteggia injury instead centers on a proximal ulna fracture with radial head dislocation.

24635 billing questions
When should this code be used instead of 24620?
Use 24635 when the Monteggia fracture-dislocation is treated through an open operation. Code 24620 describes closed treatment of that injury.
Does the injury need both an ulna fracture and a radial head dislocation?
Yes. The defining pattern is a proximal ulna fracture associated with radial head dislocation; an isolated elbow dislocation or proximal ulna fracture is a different injury.
What documentation supports reporting 24635?
The record should identify the Monteggia fracture-dislocation and document the open reduction and operative management, including fixation performed when applicable.
How is the code handled when other procedures occur in the same session?
The highest-valued procedure is paid in full, with other procedures paid at 50% under the standard multiple procedure reduction. The 90-day global period includes related postoperative care.
Can an assistant or co-surgeon be reported?
Assistant-at-surgery services may be paid. Co-surgeon payment requires supporting documentation; team surgery is not permitted.
How is bilateral surgery reported?
For bilateral procedures, modifier 50 is paid at 150%.
