About 22802: Posterior deformity spinal fusion, 7-12 segments
Posterior fusion for spinal deformity across 7 to 12 vertebral segments is reported for operative correction of conditions such as scoliosis or kyphosis.
This code describes posterior spinal arthrodesis for a deformity when the fusion spans 7 to 12 vertebral segments. Spine surgeons, including orthopedic spine surgeons and neurosurgeons, use it in operative correction of conditions such as scoliosis or kyphosis. The service is typically performed in a hospital or other surgical facility and may be part of a larger deformity-correction procedure.
Select the code based on the posterior approach, the deformity indication, and the documented extent of the fusion; the operative report should identify the levels treated and the fusion performed. Instrumentation and bone graft services may be separately coded when supported by the operative work. CMS assigns a 90-day global period, including the day-before preoperative visit and related postoperative care. When multiple procedures are performed in the same session, the highest-valued is paid in full and other procedures are subject to the standard 50% reduction. Modifier 50 is inappropriate for this spinal service. Assistant-at-surgery payment may be made; co-surgeon payment requires supporting documentation, and team surgery is not permitted.

22802 billing questions
How is this code distinguished from 22800 or 22804?
Choose 22802 for posterior deformity arthrodesis spanning 7 to 12 vertebral segments. Code 22800 covers fewer than 6, while 22804 covers 13 or more.
Can spinal instrumentation be reported with this fusion?
Instrumentation may be reported separately when performed and documented. For posterior segmental instrumentation spanning 7 to 12 vertebral segments, consider 22843.
What operative documentation supports 22802?
Document the deformity being treated, the posterior approach, the fusion performed, and the vertebral levels establishing the 7-to-12-segment extent.
Does the code have a global period?
Yes. CMS assigns a 90-day global period that includes the day-before preoperative visit and 90 days of related postoperative care.
Can an assistant or co-surgeon be reported?
CMS allows assistant-at-surgery payment. Co-surgeon payment requires supporting documentation; team surgery is not permitted.
Should modifier 50 be appended for bilateral spinal treatment?
No. Modifier 50 is inappropriate for this code; report the service based on the documented posterior fusion construct.
