A multi-provider spine surgery practice in New York faced reimbursement gaps despite consistent surgical volume, timely claim submission, and controlled denial rates.

Customer Situation
The practice performed a steady volume of high-value procedures for spinal stenosis, degenerative disc disease, spondylolisthesis, and revision spine surgery. Despite consistent surgical volume, reimbursement growth had stalled.
Commercial claims involving multi-level fusion and instrumentation frequently received partial payments that appeared reasonable. The billing team focused on denials and aging accounts, while paid claims were closed after payment posting.
This created a significant blind spot. As reimbursement pressure continued to increase for spine procedures, validating payments against contracted reimbursement rates became essential to protecting earned revenue.
Our Assessment Highlights
Our review identified several recurring reimbursement issues affecting commercial payer payments for complex spine procedures.
High-Value Fusion Claims Were Paid Below Contract
Claim-level analysis identified recurring reimbursement variances for CPT 22633, 22614, 22842–22847, and 22853. Primary fusion procedures were paid correctly, but additional levels and instrumentation were consistently under-reimbursed.
Outdated Fee Schedules Were Still Applied
Several commercial claims were processed using outdated reimbursement schedules instead of current negotiated contract rates, resulting in recurring payment variances across multiple providers.
Multiple-Procedure Logic Reduced Allowables Incorrectly
Certain commercial payers incorrectly applied multiple-procedure reductions to add-on fusion and instrumentation services, lowering reimbursement for complex spine procedures.
Paid Claims Bypassed Follow-Up
Because claims were partially paid rather than denied, they bypassed standard follow-up workflows, allowing contractual underpayments to go unnoticed.
Recovery Windows Were Narrowing
Several underpaid claims were approaching payer reconsideration deadlines, limiting recovery opportunities on high-value surgical cases.
