Spine surgery
About 22808: Anterior spinal deformity fusion, 2–3 segments
Anterior fusion for spinal deformity involving two or three vertebral segments, such as a surgical correction of a structural spinal curve.
This service surgically joins two or three vertebral segments through an anterior approach as part of correcting a spinal deformity. Spine surgeons, including orthopedic spine surgeons and neurosurgeons, may perform it for conditions such as scoliosis when an anterior fusion is part of the operative plan. It is generally performed in a hospital operating room rather than an office setting.
Select this code when the operative report supports an anterior deformity fusion and documents two or three segments included in the arthrodesis. Do not select it based only on the number of vertebrae exposed or on instrumentation placed; the fusion approach, deformity indication, and segments fused should be clear. The service has a 90-day global period, including the day-before preoperative visit and 90 days of related postoperative care. For multiple procedures in the same session, the highest-valued procedure is paid in full and other procedures at 50%. Modifier 50 is inappropriate. Assistant-at-surgery payment may be available; co-surgeon payment requires supporting documentation, and team surgery is not permitted.

22808 billing questions
How is this code distinguished from the larger anterior deformity fusion codes?
Use this code for two or three fused vertebral segments. The related anterior codes 22810 and 22812 describe larger segment counts.
Can this be reported with anterior instrumentation?
Anterior instrumentation may be separately reportable when performed; for two or three segments, 22845 is the related instrumentation code. Document the fixation work separately in the operative report.
Should modifier 50 be appended for a bilateral spinal procedure?
No. The CMS bilateral adjustment does not apply to this code, and modifier 50 is inappropriate.
What postoperative care is included?
The 90-day global period includes the day-before preoperative visit and 90 days of related postoperative care.
Can an assistant surgeon or co-surgeon be paid?
Assistant-at-surgery payment may be available. Co-surgeon payment requires supporting documentation; team surgery is not permitted.
How are other procedures in the same session paid?
Under the standard multiple procedure reduction, the highest-valued procedure is paid in full and other procedures are paid at 50%.
Where these rates come from
FeeBase calculates base physician payments from CMS work, practice-expense, and malpractice RVUs, adjusted by each locality’s geographic indices and the applicable conversion factor. Unavailable or separately priced services are labeled rather than assigned a made-up amount.
