What 22585 covers

22585 represents fusion at an additional intervertebral space using an anterior interbody approach. The surgeon removes disc material as needed to prepare the space for fusion; this code describes preparation for fusion, not a separate nerve-root or spinal-cord decompression. It may be used for additional cervical, thoracic, or lumbar spaces when the corresponding primary anterior interbody fusion procedure is performed. Spine surgeons, including orthopedic surgeons and neurosurgeons, typically perform these operations in an operating room.

Report 22585 only with the appropriate primary code for the first interspace, such as 22554, 22556, or 22558. The operative report should identify each fused interspace and support that 22585 represents an additional space beyond the one reported by the primary code. CMS classifies 22585 as an add-on code: it is not billed by itself, and its payment falls within the primary procedure’s global period.
