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.

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