CPT 22630 covers posterior lumbar interbody fusion (PLIF), a spinal surgery where a surgeon removes a damaged disc in the lower back and fuses two vertebrae together using bone graft material inserted from the back of the spine.
This calculator gives a typical-case estimate using standard Medicare modifier rules. Actual payment depends on payer policies, documentation, code-specific CMS status indicators, and locality. Verify before billing.

Billing tips
Always use add-on code 22632 for each additional interspace beyond the first level in the same operative session
Impact: Each additional level adds approximately $1,200-$1,400 in reimbursement; billing 22630 twice instead of 22630 + 22632 will result in denial
Bill instrumentation separately using 22842 (posterior segmental instrumentation, 3-6 vertebral segments) when hardware is placed
Impact: Adds approximately $2,500-$3,500 to total reimbursement; must document specific hardware placed and levels instrumented
Report bone graft procurement separately if autograft is harvested from separate incision (20936 for structural, 20937 for morselized, or 20938 for iliac crest)
Impact: Adds $400-$800 depending on graft type; local graft taken through same incision is included in 22630 and should not be separately billed
Verify commercial payer policies regarding facility vs. non-facility designation; most require inpatient or hospital outpatient setting
Impact: Both facility and non-facility rates are $1,544.22 for Medicare in 2025, but commercial contracts may vary significantly; ASC rates are typically lower
Document the specific interspace treated (e.g., L4-L5, L5-S1) in both the operative report and on the claim to prevent denials for lack of specificity
Impact: Prevents denials and requests for medical records; specific anatomic documentation reduces audit risk by approximately 30-40%
Bundle fluoroscopy and imaging guidance into the surgical code; do not separately bill 77003 for fluoroscopic guidance during fusion
Prevents NCCI edit denials; separately billing bundled services triggers automatic denials and potential audit flags
