What 22843 covers
Code 22843 represents posterior segmental fixation spanning 7 through 12 vertebral segments. Typical constructs use pedicle screws and rods or other segmental anchors, such as multiple hooks or sublaminar wires, to stabilize a long portion of the spine. Orthopedic spine surgeons and neurosurgeons commonly place this instrumentation during facility-based operations for spinal fusion, deformity correction, or extensive instability.
Choose the code by counting the vertebral segments instrumented, not the disc spaces fused. The operative report should identify the spinal levels and describe the fixation construct so the 7–12 segment span is supported. This is an add-on code: report it only with an appropriate primary procedure. CMS pays it within that primary procedure’s global period, rather than assigning it a separate global period.
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.

22843 billing questions
How is 22843 distinguished from 22842 or 22844?
Count the vertebral segments included in the posterior segmental construct. Code 22843 is for 7–12 segments; 22842 covers a shorter span, and 22844 covers a longer one.
Does 22843 require a primary procedure?
Yes. It is an add-on code and must be reported with an eligible primary procedure, such as a spinal fusion when the operative work supports both services.
Are instrumented segments the same as fusion levels?
No. Select the code from the vertebral segments included in the fixation construct, not simply the number of disc spaces fused. The operative report should make the instrumented span clear.
Can 22843 be reported with an interbody device code?
It may be reported with a separate interbody-device service, such as 22853, when that device is placed and the documentation supports both services. The fixation construct and interbody device represent different work.
Does 22843 have its own global period?
No separate global period is assigned. Payment is within the global period of the primary procedure.
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.
