About 22804: Posterior spinal deformity fusion, 13 or more segments
Posterior fusion of 13 or more vertebral segments to correct a spinal deformity, such as extensive scoliosis or kyphosis.
This code represents a posterior fusion spanning 13 or more vertebral segments to correct a spinal deformity, such as extensive scoliosis or kyphosis. An orthopedic spine surgeon or neurosurgeon typically performs the operation in a hospital operating room. The operative report should identify the posterior approach, the deformity being corrected, and the vertebral segments included in the fusion. Segment count is based on the vertebrae fused, not the number of screws or rods used.
Report this code when the documented posterior fusion reaches the 13-segment threshold; the shorter posterior deformity-fusion codes apply to smaller spans. Report spinal instrumentation separately when performed and supported by the operative details. The 90-day global includes the day-before preoperative visit and related care for 90 days after surgery. When multiple procedures occur in the same session, the highest-valued is paid in full and the others at 50%. Modifier 50 is inappropriate. Assistant-at-surgery payment may be available; co-surgeons require supporting documentation, and team surgery is not permitted.

22804 billing questions
How is 22804 distinguished from 22802?
Use 22804 for posterior deformity fusion of 13 or more vertebral segments. Use 22802 when the posterior fusion spans 7 through 12 segments.
Does the fusion code include spinal instrumentation?
Instrumentation is reported separately when it is performed and supported by the operative documentation. For a posterior construct spanning 13 or more segments, 22844 may describe the instrumentation.
What documentation supports the segment count?
The operative report should state the posterior approach and identify the vertebral segments included in the fusion. Count the fused vertebral segments, not the implanted screws or rods.
How does the multiple-procedure rule affect payment?
For multiple procedures performed in the same session, the highest-valued procedure is paid in full and the others at 50%.
Can an assistant or co-surgeon be reported?
Assistant-at-surgery payment may be available. Co-surgeons are paid only with supporting documentation; team surgery is not permitted.
What care is included in the global period?
The 90-day global includes the day-before preoperative visit and related postoperative care for 90 days after surgery.
