Insurance Claim Supplement — Challenge Underpayments and Get Paid in Full
When your insurance claim comes back short, an insurance claim supplement is how you fight back. We build detailed, documented supplements that challenge carrier underpayments with Xactimate pricing data, code citations, and photo evidence — and we don't stop until your claim is approved.

Claim Underpayment Analysis
We analyze the carrier's initial payment against your actual scope of work and calculate the exact underpayment amount. This analysis becomes the backbone of your supplement claim.
Line-by-Line Supplement Build
We add every missing item to the claim with proper Xactimate codes, correct quantities, and written justifications. Carriers approve well-documented supplements faster and more often.
Supporting Documentation
We compile manufacturer specs, local building codes, material invoices, and photo documentation to support every line item in your supplement. Documented claims are paid claims.
Follow-Up & Rebuttal
If the carrier denies supplement items, we write formal rebuttals and escalate through the carrier's review process. Most contested supplements are ultimately approved with proper persistence.
