Medical Bill Audit —
You Probably Overpaid.
Let's Prove It.

Studies show 80% of medical bills contain errors — duplicate charges, wrong codes, phantom services. Our free tools and expert human advocates help patients find and fight back before they pay.

The Reality of Medical Billing

The Numbers Don't Lie

Medical billing is one of the most complex and error-prone processes in any industry. Patients who don't verify their bills routinely pay for mistakes they didn't cause.

80% of hospital bills contain at least one billing error — per multiple CMS studies

The Process

How to Audit Your Medical Bill

1

Request Your Itemized Bill

Call the hospital billing department and ask specifically for an "itemized statement." This lists every charge individually — which is what you need to audit.

2

Enter Line Items Into Our Audit Tool

Use MediHelp's free Bill Audit tool to enter each charge. Our engine automatically cross-checks CPT codes, Medicare benchmarks, and bundling rules.

3

Review Red-Flagged Findings

Errors are highlighted in real-time with an explanation of the issue and the estimated overcharge amount. You can export a dispute letter directly from the tool.

4

Dispute or Get Expert Help

Use the dispute letter template to challenge errors yourself, or open a case with our human negotiation service for complex, high-balance bills.
