What 22847 covers
This code represents placement of anterior fixation across seven to twelve vertebral segments. A spine surgeon may use a plate-and-screw construct or other anterior fixation to stabilize a long spinal reconstruction, often during multilevel fusion. The surgeon approaches the spine from the front, such as through the neck for cervical surgery or through the chest or abdomen for thoracic or lumbar surgery. The segment count is based on the vertebral levels instrumented, not the number of screws or implants used.
Report this code as an add-on with an eligible primary procedure; it is not billed by itself. The operative report should identify the anterior approach, the instrumented vertebral segments, and the fixation placed. Select this level when the construct spans seven through twelve vertebral segments, rather than the shorter ranges represented by 22845 or 22846. CMS treats payment as part of the primary procedure’s global period, so the add-on is paid within that period.

How to choose
- 22846Spinal fixationAnterior, four to seven segments
- Use 22846 when anterior fixation spans four to six vertebral segments. Use 22847 for seven to twelve.
- 22845Anterior fixationTwo to three vertebral segments
- 22845 is for anterior fixation across two to three vertebral segments; 22847 is for the longer seven-to-twelve-segment construct.
- 22843Spinal fixation7–12 vertebral segments
- Both codes represent segmental fixation over seven to twelve vertebral segments, but 22843 is for a posterior construct and 22847 for an anterior construct.
- 22853Interbody deviceWith interbody arthrodesis
- 22853 concerns an interbody biomechanical device, such as a cage placed in a disc space. 22847 represents anterior fixation spanning multiple vertebral segments.
22847 billing questions
How is this code distinguished from 22846?
Count the vertebral segments instrumented. This code is for seven to twelve segments; 22846 covers the shorter four-to-six-segment range.
Can this code be reported by itself?
No. It is an add-on code and must be reported with an eligible primary procedure.
Does the number of screws determine the code level?
No. The level is selected by the number of vertebral segments instrumented, not by the number of screws or other fixation pieces.
What documentation supports reporting this code?
The operative report should establish the anterior approach, identify the vertebral segments spanned, and describe the fixation construct placed.
How does this differ from 22843?
22847 represents anterior fixation across seven to twelve segments. 22843 represents posterior segmental fixation across that segment range.
