Spine surgery
About 22847: Anterior spinal fixation, seven to twelve segments
Reports anterior spinal fixation spanning seven to twelve vertebral segments, typically added to a long-segment fusion or other eligible primary spine procedure.
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.

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.
Where these rates come from
FeeBase calculates base physician payments from CMS work, practice-expense, and malpractice RVUs, adjusted by each locality’s geographic indices and the applicable conversion factor. Unavailable or separately priced services are labeled rather than assigned a made-up amount.
