Use 22840 for posterior nonsegmental fixation, such as fixation across one motion segment. Use 22842 when posterior segmental instrumentation spans three to six vertebral segments.

Spinal instrumentation
About 22842: Posterior segmental spinal fixation, three to six segments
Reports posterior segmental spinal fixation spanning three to six vertebral segments, commonly added to a fusion procedure requiring multilevel stabilization.
This code describes posterior segmental fixation spanning three to six vertebral segments, using connected hardware such as rods with pedicle screws, hooks, or wires. Spine surgeons commonly place this instrumentation during surgery for spinal fusion when multilevel stabilization is needed, including for deformity or instability. The code identifies the fixation construct, not the spinal fusion itself or an interbody device.
Select the code by the number of vertebral segments spanned by the posterior segmental construct, not by the number of screws or other individual implants. The operative report should establish the posterior approach, segmental fixation method, and levels instrumented. This is an add-on code: report it with an eligible primary procedure, not by itself. CMS pays it within the primary procedure’s global period.

22842 compared with similar codes
Office rates for Wyoming, from the same CMS release.
Both describe posterior segmental instrumentation; 22843 is for a construct spanning more vertebral segments than 22842.
22845 describes anterior instrumentation across a limited span. Choose based on the approach and construct, rather than treating anterior and posterior fixation as interchangeable.
22853 concerns insertion of an interbody biomechanical device. It does not describe the posterior segmental fixation reported with 22842.

How this local rate is calculated
Each RVU component is multiplied by its own geographic practice cost index (GPCI). The three adjusted components are added, then multiplied by the conversion factor. These are the inputs used for 22842 in Wyoming**.

22842 billing questions
How do I distinguish this code from 22840?
This code is for posterior segmental fixation spanning three to six vertebral segments. Code 22840 describes posterior nonsegmental fixation, typically spanning one motion segment or using a nonsegmental technique.
How are the segments counted?
Count the vertebral segments spanned by the fixation construct, rather than the number of screws, hooks, or rods. The operative report should identify the instrumented levels and the construct.
Can 22842 be reported by itself?
No. It is an add-on code and must be reported with an eligible primary procedure. For example, posterior lumbar fusion code 22612 may be a primary procedure when performed with the instrumentation.
Is an interbody device included in this service?
This code describes posterior fixation, not insertion of an interbody biomechanical device. When an interbody device is placed, determine separately whether the applicable device code is supported.
What documentation supports reporting 22842?
Document the posterior approach, fixation method, and vertebral levels spanned. The record should support a segmental construct across three to six vertebral segments.
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.
