Adult Spine Deformity & Multi-Level LLIF Scrubber

Minimally invasive adult spinal deformity reconstruction combines multi-level lateral lumbar interbody fusion (LLIF/XLIF) with anterior longitudinal ligament release (ALLR) and percutaneous posterior spinopelvic instrumentation. Yet commercial payers aggressively bundle multi-level add-ons (+22552), claw back ALLR Modifier -22 fee enhancements, and disallow S2AI pelvic anchors (+22848). Verify and protect your surgical claims.

Minimally Invasive Spine Deformity Engine

Adult Spine Deformity & Multi-Level LLIF Scrubber

Eliminate severe undercoding and modifier unbundling rejections on multi-level lateral lumbar interbody fusions (LLIF/XLIF). Defend primary arthrodesis (22558), multi-level add-ons (+22552), ALLR anterior release (+Mod 22), percutaneous instrumentation (+22842–+22843), and spinopelvic iliac anchors (+22848).

1. Lateral Interbody Corridors (LLIF/XLIF)

3 Interspaces

Level 1 bills CPT 22558 ($2,850). Levels 2–3 bill add-on +22552 ($1440).

Payer Scrubber & Audit Defenses

Submit dedicated Modifier -22 justification note detailing exact operative time increase (>45 mins) and vascular mobilization for ALLR.
Ensure each interspace (2 add-on levels) has explicit discectomy, endplate preparation, and trial notes to survive automated NCCI edits.
Verify CPT +22848 is reported with posterior instrumentation (+22842/+22843). Never bill alone.
