Most medical bills have errors.
Is yours one of them?
Medical billing is complex by design. Errors happen — and hospitals don't fix them unless someone pushes back. Upload your bill and we check every charge against Medicare rates, federal law, and your insurer's own policy terms. You pay $29 only if we find errors.

FAQ
How do I know your analysis is accurate?
Every charge is cross-referenced against the Medicare Physician Fee Schedule and hospital rate databases. We match CPT codes against standard definitions to catch upcoding and duplicates, then apply the No Surprises Act, EMTALA, ACA, and applicable state balance billing laws. Any charge that exceeds Medicare benchmarks or violates a patient protection law is flagged with the specific regulation cited.
What information do I need to share?
Only billing details — line items, dates of service, CPT codes, and dollar amounts. Never your Social Security number, date of birth, or any personal identifiers.
Is my data safe?
Your bill is processed in server memory and never written to disk. When the analysis is complete the input is discarded — nothing is stored in a database. AI analysis is handled by Anthropic's Claude API under a zero data retention policy, meaning Anthropic does not store or train on your content. Payments are processed through Stripe.
What if you find nothing wrong with my bill?
The check is free, so you pay nothing. If you do pay and aren't satisfied, email support@billcheck.app within 7 days for a full refund.
What bills can you analyze?
ER visits, hospital stays, outpatient procedures, specialist visits, lab work, imaging — any US hospital or insurer.
Will disputing a charge cause problems with the hospital or hurt my credit?
Disputing a billing error is your legal right. Hospitals are required to review documented disputes, and citing a specific law or billing code puts your objection formally on the record. A dispute is not the same as a delinquent bill — hospitals cannot send a legitimately disputed charge to collections while it's under active review. For large or complex disputes, a certified patient advocate can help you navigate the process.
Can I upload a photo of my bill?
Yes. PDF, JPG, PNG, HEIC, and WebP are all supported. Our AI extracts the billing details automatically.
Is this legal advice?
No. BillCheck is an educational tool only and is not legal or medical advice. For complex disputes, consult a healthcare attorney or certified patient advocate.
