Questions
Is this legal advice?›
No. OverBilled is an AI analysis tool, not a law firm. We identify potential errors and generate dispute letters for informational purposes. Consult a healthcare attorney for complex cases.
What if no errors are found?›
You pay nothing. The $29 fee only applies when you choose to download your dispute letter. If no errors are found, you see that result at no charge.
How long does the analysis take?›
About 20 seconds. Our AI reads your bill and checks for the most common billing errors immediately.
Is my bill data stored anywhere?›
No. Your bill is analyzed in memory and never written to a database or stored on our servers. We take privacy seriously.
What types of bills can I upload?›
Hospital bills, physician invoices, EOBs, specialist bills, and outpatient procedure statements. PDF or image files up to 10MB.
Does the dispute letter actually work?›
Providers are legally required to respond to formal written disputes. A documented letter citing specific errors gives you strong grounds to request corrections.
