Use 22842 when posterior segmental fixation covers 3–6 vertebral segments. Use 22843 when the construct includes 7–12.

About 22843: Posterior segmental spinal fixation, 7–12 segments
Reports posterior segmental fixation spanning 7–12 vertebral segments, commonly placed with spinal fusion or reconstruction to stabilize a long spinal construct.
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.

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 in the CMS facts for this add-on code. 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 indices and the applicable conversion factor. Unavailable or separately priced services are labeled rather than assigned a made-up amount.
