Questions people ask
Is this tool free? Do you see my bill?+
It's 100% free with no signup. Everything runs in your browser, so your bill, name and insurance details never leave your device.
Do medical bills really contain errors?+
Yes, often. Duplicate charges, services you didn't receive and charges that should have gone to insurance are common. Always ask for an itemized bill and compare it with your insurer's Explanation of Benefits.
Does disputing a bill hurt my credit?+
No. Asking for an itemized bill, appealing a denial or requesting financial assistance doesn't affect your credit. Ask the provider to hold the account while it is reviewed so it doesn't go to collections.
Is this legal advice?+
No. It's general information based on federal rules and ready-to-edit letter templates. State laws and your plan documents may give you more rights. For large amounts, consider a patient advocate or attorney.
