About 22534: Additional-level lateral extracavitary spinal fusion
Reports an additional thoracic or lumbar vertebral segment fused through a lateral extracavitary approach, alongside the applicable primary arthrodesis code.
This add-on represents fusion of an additional vertebral segment using a lateral extracavitary approach to the thoracic or lumbar spine. The surgeon prepares the interspace for fusion, including limited disc removal for that purpose; the code does not describe disc removal performed as decompression. Orthopedic spine surgeons and neurosurgeons typically report it for multilevel fusion performed in an operating room.
Report 22534 for each additional segment beyond the segment represented by the primary procedure. The operative report should identify the spinal levels fused and support the lateral extracavitary technique; select the primary code according to the region of the initial segment. CMS treats 22534 as an add-on: it is billed only with a primary procedure and paid within that procedure’s global period.

22534 billing questions
Which primary code is reported with 22534?
Use 22532 for a thoracic primary segment or 22533 for a lumbar primary segment. 22534 represents an additional segment, not the primary fusion.
Can 22534 be submitted by itself?
No. It is an add-on code and must be billed with its applicable primary arthrodesis procedure.
How many units of 22534 should be reported?
Report a unit for each additional vertebral segment treated beyond the segment represented by the primary code. The operative report should identify the fused levels.
Is disc preparation included?
Limited disc removal to prepare the fusion interspace is part of the service. The code does not represent disc removal performed for decompression.
How does CMS treat payment for 22534?
CMS treats it as an add-on billed with a primary procedure and pays it within that procedure’s global period.
