Scan a hospital bill and see what's worth questioning. Every finding quotes the exact billed line — verified word for word and dollar for dollar — with the letter to send about it.
Built for anyone staring at a confusing US medical bill — not a chatbot that bluffs.
Every finding quotes the exact billed line. The quote and the dollar amount are double-checked against your document — anything that can't be matched is marked unverified, not hidden.
A summary bill or EOB hides the line items, so a real audit isn't possible yet. BillHawk says so — then drafts the itemized-bill request that unlocks the audit that counts.
Itemized-bill requests, billing-office inquiries built from your findings, and federal dispute prep — facts-only drafts you send in your own name.
Your bill is deleted from our servers within 24 hours. The audit stays on your device. No account, no ads, no tracking.
The audit takes 15–45 seconds. No account, no waiting on a human.
Scan a paper bill with your camera, snap a photo, or import a PDF from your patient portal.
BillHawk audits every line, ranks findings by severity, and quotes the exact charge behind each one.
Generate the letter to send, or ask “what is this facility fee?” — answers quote your bill's own lines.
If the line items are hidden, there's nothing real to check — and pretending otherwise is how you end up disputing the wrong thing.
So BillHawk tells you the truth about the document in your hand, then walks you to the one you can actually audit.
Findings, letters, and follow-up questions included — no account, no card.

Download on the App StoreBillHawk explains what your bill says and what's worth asking about. It doesn't declare errors or amounts owed, and it isn't medical, legal, or financial advice. About half of US medical bills contain at least one error, by industry estimates — BillHawk helps you spot what's worth questioning and take it to your provider or insurer.
