What 22600 covers
An orthopedic spine surgeon or neurosurgeon uses a posterior approach to prepare and fuse one cervical interspace below C2, joining the adjacent vertebrae with bone graft. The procedure is performed in an operating room, commonly for cervical instability or degenerative disease requiring fusion. Instrumentation or graft services may be separately reportable when performed and supported by the operative record.
Report 22600 for the first interspace treated with this technique; document the fused level and posterior approach. When additional eligible vertebral segments are fused, report add-on code 22614 for each additional segment. The 90-day global period includes the day-before preoperative visit and 90 days of related postoperative care. In a session with multiple procedures, the highest-valued procedure is paid in full and other procedures are subject to the standard 50% reduction. Assistant-at-surgery payment may be available, and co-surgeons are permitted; team-surgery payment is not permitted for this code.

- 22612Spinal fusionPosterior lumbar, single level
- 22612 describes posterior or posterolateral fusion at a lumbar interspace. Use 22600 when the fused interspace is cervical and below C2.
- 22630Lumbar fusionSingle lumbar interspace
- 22630 describes lumbar posterior interbody fusion. It differs from 22600 in both spinal region and fusion approach.
22600 billing questions
When should 22600 be selected instead of 22610 or 22612?
Use 22600 for a posterior or posterolateral fusion at a cervical interspace below C2. Codes 22610 and 22612 describe the same general technique in the thoracic and lumbar regions, respectively.
How are additional fused levels reported?
Report 22600 for the initial cervical interspace and 22614 for each additional eligible vertebral segment. The operative report should identify the levels fused.
Is spinal instrumentation included in 22600?
Instrumentation is not described by 22600. When instrumentation is performed, its separate reporting depends on the documented construct and the applicable instrumentation code.
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 or co-surgeon be reported?
CMS allows assistant-at-surgery payment and permits co-surgeons for 22600. Team-surgery payment is not permitted for this code.
