What 22845 covers
22845 reports placement of anterior spinal fixation across two or three vertebral segments as part of a spine operation. A common example is an anterior cervical plate secured with screws across the operative vertebrae during cervical fusion; anterior fixation may also be used with thoracic or lumbar procedures. The work is typically performed by an orthopedic spine surgeon or neurosurgeon in an operating room. This code represents supplemental stabilization, not an interbody cage or the fusion itself.
Select the code based on the vertebral segments actually instrumented, not simply the number of disc spaces treated. The operative report should identify the anterior approach, device placement, segments spanned, and associated primary procedure. 22845 is an add-on code: report it only with an eligible primary procedure, and Medicare payment is handled within that procedure’s global period. It is not a standalone service. For fixation spanning more segments, use the applicable higher segment-count code when supported by the operative details.
This summary was written with AI assistance from CMS physician fee schedule data and checked against the CMS billing rules shown here. Rates on this page come directly from CMS files.

22845 billing questions
How is 22845 distinguished from 22846?
22845 is for anterior fixation spanning two or three vertebral segments. 22846 applies when the anterior fixation spans four to seven segments.
Can 22845 be billed by itself?
No. It is an add-on code and must be reported with an eligible primary procedure; Medicare payment is handled within that procedure’s global period.
What documentation supports the segment count?
The operative report should describe the anterior fixation device and identify the vertebral segments it spans. Count the instrumented segments rather than assuming the count from the number of treated disc spaces.
Is an interbody cage reported with 22845?
The codes describe different work: 22845 represents anterior fixation, while 22853 describes placement of an interbody biomechanical device. They may be reported for distinct work in the same fusion operation when documented.
Does 22845 describe the fusion itself?
No. It describes supplemental anterior stabilization. Report the applicable primary fusion or other procedure separately.
Where these rates come from
FeeBase calculates base physician payments from CMS work, practice-expense and malpractice RVUs, adjusted by each locality’s geographic indexes and the conversion factor. Services without a published rate are labeled, never given a made-up amount. Amounts are Medicare allowed amounts before claim adjustments: not a patient’s bill or a commercial rate.
