Billing code 24620: Monteggia treatmentMedicare rate & RVUs

Medicare pays $567.82 for 24620 nationally in a facility.

Medicare allowed amount for participating (non-QP) physicians, before deductible, coinsurance and claim adjustments. Not a patient’s bill or a hospital charge.

What 24620 covers

A Monteggia injury combines a proximal ulna fracture with dislocation of the radial head at the elbow. This code describes closed treatment when the provider manages the injury without manipulating the fracture or dislocation, typically with immobilization. Orthopedic surgeons commonly provide this care in a hospital or other facility setting; the diagnosis and treatment plan should identify the fracture-dislocation pattern and the nonoperative approach.

Select this code based on the documented Monteggia injury and the fact that no manipulation was performed. The record should support the fracture and radial head dislocation, the treatment provided, and the decision to manage the injury closed. CMS assigns a 90-day global period, including the day-before preoperative visit and 90 days of related postoperative care. When multiple procedures occur in the same session, the highest-valued procedure is paid in full and others at 50%. Modifier 50 pays bilateral procedures at 150%. Assistant-at-surgery payment requires documented medical necessity; co-surgeons and team surgery are not permitted.

This code is for closed treatment without manipulation of a proximal ulna fracture without a radial head dislocation. A documented Monteggia pattern points to 24620.

24675Fracture treatment

This code describes closed treatment with manipulation of a proximal ulna fracture, not a Monteggia fracture-dislocation. The injury pattern and whether manipulation occurred distinguish the services.

24600Elbow reduction

This code addresses closed treatment of an elbow dislocation without anesthesia, rather than a Monteggia fracture-dislocation involving a proximal ulna fracture.

Where these rates come from

FeeBase calculates base physician payments from CMS work, practice-expense and malpractice RVUs, adjusted by each locality’s geographic indexes and the conversion factor. Services without a published rate are labeled, never given a made-up amount. Amounts are Medicare allowed amounts before claim adjustments: not a patient’s bill or a commercial rate.
