Spine surgery
About 22220: Anterior cervical vertebral osteotomy
Report an anterior cervical osteotomy with disc removal when a surgeon releases one vertebral segment to correct a fixed cervical deformity.
This service involves an anteriorly approached osteotomy at one cervical vertebral segment, with removal of the intervening disc as part of the release. A spine surgeon may perform it to mobilize a fixed deformity, such as cervical kyphosis, when correction requires an osteotomy rather than routine disc decompression. It is performed in the operating room and may be part of a larger reconstruction or fusion procedure.
Report one unit for the cervical segment actually osteotomized. The operative report should identify the treated level, anterior approach, bony release, associated disc removal, and correction performed. Routine cervical discectomy and fusion without an osteotomy is not this service; 22226 describes each additional segment. CMS assigns a 90-day global period, including the day-before preoperative visit and 90 days of related postoperative care. For multiple procedures in one session, the highest-valued procedure is paid in full and others at 50%. An assistant at surgery may be paid; co-surgeons require supporting documentation, and team surgery is not permitted.

22220 billing questions
How is 22220 different from routine anterior cervical discectomy and fusion?
22220 requires an osteotomy to release a cervical vertebral segment for deformity correction. Routine disc removal and fusion without that osteotomy is not enough to report it.
Does 22220 include removal of the disc?
Yes. Disc removal at the treated segment is part of the osteotomy service; do not separately report that same disc removal as a separate service.
When is 22226 used with 22220?
Use 22220 for the first anterior cervical segment osteotomized and 22226 for each additional segment when documented.
What operative documentation supports 22220?
Document the cervical level, anterior approach, vertebral osteotomy and associated disc removal, and the deformity release or correction performed.
Can an assistant or co-surgeon be reported?
An assistant at surgery may be paid. Co-surgeons are paid only with supporting documentation; team surgery is not permitted.
How does the global period affect postoperative billing?
The 90-day global includes the day-before preoperative visit and 90 days of related postoperative care.
