What you get

Two things that actually move the needle

A detailed error report

Every charge is reviewed and flagged. Duplicate line items, upcoding, unbundled procedures, and charges for services not provided. We explain everything clearly, without medical jargon.

A ready-to-send dispute letter

A professional letter citing every billing violation by name with regulatory references. It is the same documentation that compels billing departments to act.

Results in minutes, not weeks

No waiting for a human advocate. No back-and-forth calls. Upload your bill and get your full report and dispute letter the same day, ready to send immediately.

Your questions, answered.

ClaroBill reviews your medical bill for the kinds of errors that quietly inflate what patients pay. That includes duplicate charges, miscoded procedures, services that were never rendered, and amounts that exceed what the hospital or your insurer has agreed to charge. You receive a plain-English report of every finding and a ready-to-send dispute letter you submit directly to your insurer or hospital.
Upload your bill as a PDF or image. Our analysis engine runs a deep audit across every line item to find errors, duplicates, and overcharges. Within minutes you receive a detailed error report and a tailored dispute letter that names each finding and cites the basis for the dispute.
No. ClaroBill gives you the report and the letter; you send it. Patients should stay in control of their own disputes. Our job is to give you documentation so precise and well-cited that billing departments take it seriously.
Yes. We work across every major US health insurer, including BlueCross BlueShield, Aetna, Cigna, UnitedHealthcare, Humana, Kaiser Permanente, Anthem, Oscar, Molina, Centene, and WellCare. We also support Medicare, Medicaid, and TRICARE. And we review bills for self-pay and uninsured patients. Our review works the same regardless of who your insurer is.
The analysis itself is always free. You see exactly how many errors were found before paying anything. If we find nothing, you pay nothing, ever. If we do find errors, the fee scales with the dollar value of the savings. See the pricing page for full tier details.
Yes. You can upload and review bills for any family member. Each bill is reviewed separately and generates its own report and dispute letter.
No. We do not use your bill, your personal information, or any data you upload to train AI models, ours or anyone else's. We do not sell, license, or share your data with advertisers, data brokers, or third parties for marketing. Your bill is used only to produce your audit report and dispute letter.
Yes. Uploads are encrypted in transit and at rest. Access is restricted to the systems that produce your report and is logged for audit. We retain your bill only as long as your account is active; you can delete it at any time. We never sell or share your data.
