About 22844: Long-segment posterior spinal fixation
Reports posterior segmental spinal fixation spanning 13 or more vertebral segments, commonly used during long constructs for deformity correction or spinal reconstruction.
Code 22844 represents a long posterior fixation construct spanning at least 13 vertebral segments. An orthopedic spine surgeon or neurosurgeon may place rods, screws, or other fixation components during surgery for conditions such as major scoliosis or complex spinal deformity. These procedures are typically performed in a hospital operating room, often alongside spinal fusion or another primary spine procedure.
Select this code based on the number of vertebral segments instrumented, not the number of implants. The operative report should establish the posterior approach, the extent of the construct, and the primary procedure performed. Medicare treats 22844 as an add-on code: report it only with a primary procedure, and its payment falls within that procedure’s global period. It is not reported as a standalone service.

22844 billing questions
When should 22844 be chosen instead of 22843?
Choose 22844 when the posterior segmental construct spans 13 or more vertebral segments. Code 22843 applies to a shorter construct of 7 through 12 segments.
Can 22844 be reported by itself?
No. It is an add-on code and must be reported with a primary procedure; Medicare payment falls within that procedure’s global period.
Is the code based on the number of screws or rods?
No. Selection depends on the number of vertebral segments instrumented, not the number of screws, rods, or other implants.
What documentation supports reporting 22844?
The operative report should identify the posterior construct and the vertebral segments instrumented, supporting a span of 13 or more segments, as well as the accompanying primary procedure.
How does 22844 differ from 22840?
Code 22844 describes a long posterior segmental construct. Code 22840 is for a nonsegmental fixation method and is not selected by counting 13 or more instrumented segments.
