Decode the codes, check the prices, and find out which amounts you are not actually required to pay.
What CO-45, PR-1 and CO-97 mean — and whether that amount can be billed to you at all.
Compare your charge to the hospital's own federally required published price file.
Place-of-service and HCPCS codes — including the one that explains surprise facility fees.
What common procedures typically cost, and how far your bill sits from that.
Whether federal surprise-billing protections apply to your bill.
Put the itemised bill next to the explanation of benefits from your insurer and compare one number: what the EOB says is your responsibility, against what the provider is asking for. If the provider's figure is higher, the difference is usually an amount that should have been written off — and that single comparison finds more money than anything else a patient can do unaided.
Then work the codes. The denial code decoder tells you which adjustments are legitimately yours and which are the provider's to absorb.
What a code means, whether an amount is billable, what a hospital published as its own price — none of that should sit behind a paywall, and most of it is public if you know where to look.
What VerifyDoc charges for is doing it across a whole bill at once: every line, every code, every unit reconciled against the EOB, with the discrepancies written up in plain English and ready to dispute.
