About 22812: Extensive anterior spinal deformity fusion
Anterior fusion for spinal deformity spanning eight or more vertebral segments, often reported for extensive scoliosis correction performed through an anterior approach.
This code describes an anterior approach arthrodesis performed to correct a spinal deformity across at least eight vertebral segments. A spine surgeon typically performs the operation in an operating room, preparing the involved levels for fusion and correcting the deformity through the anterior exposure. Extensive scoliosis is a common clinical context; the code is selected by the documented extent of the fusion, not by the incision length or number of implants.
The operative report should establish the deformity indication, anterior approach, and vertebral segments included in the arthrodesis. The service has a 90-day global period, including the day-before preoperative visit and related postoperative care during that period. When multiple procedures are performed in the same session, the highest-valued procedure is paid in full and other procedures are subject to the standard 50% reduction. Modifier 50 is not appropriate for this spinal segment service. Assistant-at-surgery payment may be made; co-surgeon payment requires supporting documentation, and team surgery is not permitted.

22804 is the posterior deformity arthrodesis code for thirteen or more segments. This code describes the anterior approach and begins at eight segments.
No office rate
22847 reports anterior instrumentation across eight or more segments, not the arthrodesis itself; it may accompany the fusion when instrumentation is performed.

22812 billing questions
How is this code distinguished from 22810?
Both describe anterior arthrodesis for spinal deformity, but 22810 is for four to seven vertebral segments. This code requires eight or more.
How should the segment count be supported?
The operative report should identify the vertebral segments included in the anterior fusion. Base code selection on that documented fusion extent.
Can anterior instrumentation be reported with this fusion?
When anterior instrumentation is performed, code 22847 describes instrumentation spanning eight or more vertebral segments. The operative documentation should support the instrumentation and its extent.
Can modifier 50 be used?
No. Modifier 50 is inappropriate for this spinal segment service; it is not a procedure on paired anatomy.
How are assistant and co-surgeon services handled?
CMS permits assistant-at-surgery payment for this code. Co-surgeon payment requires supporting documentation, while team surgery is not permitted.
What happens when another procedure is performed in the same session?
The highest-valued procedure is paid in full, and the other procedures are subject to the standard multiple-procedure reduction.
