What 22558 covers
This service fuses a lumbar motion segment through an anterior approach, placing bone graft or another fusion material between the vertebral bodies. The surgeon removes enough disc material to prepare the interspace; that limited preparation is included. Orthopedic spine surgeons and neurosurgeons commonly perform the operation in a hospital operating room for lumbar instability or degenerative disc disease.
Report one unit for the treated interspace. The operative report should support the lumbar level, anterior approach, fusion, and any additional work such as decompression; extensive decompression is distinct from the limited disc preparation included here. A separately reportable interbody device may be coded with the fusion. CMS assigns a 90-day global period, including the day-before preoperative visit and 90 days of related postoperative care. When multiple procedures occur in the same session, the highest-valued procedure is paid in full and others at 50%. Bilateral adjustment is inappropriate. Assistant-at-surgery and co-surgeon payment may be allowed; team surgery is not permitted.
This summary was written with AI assistance from CMS physician fee schedule data and checked against the CMS billing rules shown here. Rates on this page come directly from CMS files.

22558 billing questions
When should 22558 be reported instead of 22554?
Use 22558 for anterior interbody fusion at a lumbar interspace. Code 22554 describes the corresponding cervical procedure.
Does 22558 include disc removal?
It includes the limited discectomy needed to prepare the interspace for fusion. Do not treat that preparation as a separate decompressive discectomy.
How is an additional lumbar interspace reported?
Report 22558 for the first lumbar interspace and consider add-on code 22585 for each additional interspace fused, when supported by the operative record.
Can an interbody device be reported separately?
A separately reportable interbody biomechanical device may be reported with 22558 using 22853. The operative documentation should identify the device and its placement.
Should modifier 50 be used for this procedure?
No. CMS identifies bilateral adjustment as inappropriate for 22558; report the lumbar interspace treated rather than treating the fusion as a bilateral service.
What payment rules affect the surgical team and follow-up?
The code has a 90-day global period that includes the day-before preoperative visit and related postoperative care. CMS permits assistant-at-surgery and co-surgeon payment, but not team-surgery payment.
Where these rates come from
FeeBase calculates base physician payments from CMS work, practice-expense and malpractice RVUs, adjusted by each locality’s geographic indexes and the conversion factor. Services without a published rate are labeled, never given a made-up amount. Amounts are Medicare allowed amounts before claim adjustments: not a patient’s bill or a commercial rate.
