Multi-Level Minimally Invasive Adult Spinal Deformity & Lateral Interbody Fusion (LLIF/XLIF) billing FAQ
How are multi-level lateral lumbar interbody fusions (LLIF / XLIF) reported under CPT?
Lateral lumbar interbody fusion is coded using primary CPT 22558 (arthrodesis, anterior interbody technique; lumbar) for the first level (e.g. L3-L4), and add-on CPT +22552 for each additional contiguous intervertebral space (e.g. L2-L3, L4-L5). Biomechanical interbody cages are reported per interspace using CPT +22853. None of the add-on codes are subject to Modifier -51 multi-procedure fee reductions.
Can stereotactic neuronavigation (+61783) and percutaneous instrumentation be billed together?
Yes. Intraoperative stereotactic computer-assisted spinal navigation is coded using CPT +61783 and is fully reimbursable when 3D navigation is utilized to guide percutaneous pedicle screw placement (+22842–+22844) and verify lateral corridor trajectories relative to the lumbar plexus.
