What 22854 covers
During spinal reconstruction, the surgeon places a biomechanical device, such as a cage or mesh, into a vertebral body defect created by corpectomy. The device spans the defect as part of an interbody fusion. Spine surgeons typically perform this work in an operating room, often with other procedures to remove diseased or damaged vertebral bone and stabilize the spine. This code is for a vertebral body defect, not a device placed in an ordinary disc space.
Report the code for each contiguous defect reconstructed with a device in conjunction with interbody arthrodesis. The operative report should identify the corpectomy defect, its location and extent, the device placement, and the fusion procedure performed. This is an add-on code: report it only with a primary procedure, and Medicare payment is included within that procedure’s global period. It is not reported as a standalone service.

22854 billing questions
When should 22854 be chosen instead of 22853?
Use 22854 for a device placed in a vertebral body defect or corpectomy defect during fusion. Use 22853 when the device is placed in an intervertebral disc space.
Is 22854 reported by device, level, or defect?
The unit is each contiguous vertebral body defect reconstructed. The operative documentation should support the number and location of the contiguous defects.
Can 22854 be billed by itself?
No. It is an add-on code and must be reported with a primary procedure; its Medicare payment falls within that procedure’s global period.
Does 22854 describe fusion or only device placement?
It describes device placement into a vertebral body defect in conjunction with interbody arthrodesis. Report the applicable primary fusion procedure as well.
How does 22854 differ from 22859?
22854 is for device placement in a vertebral body defect with interbody fusion. 22859 is for placement in a disc space or vertebral body defect without interbody arthrodesis.
