Medical bill, insurance denial, or collection notice? Scan it free. We find the errors, draft your dispute letter, and mail it certified mail. We keep $0 of your win.
They overbilled you. We prove it.
Medical bills hide errors — duplicate charges, inflated visit codes, vague "misc" fees that can't name themselves. Most people pay anyway, because fighting back feels impossible. BillFighter makes it a camera tap.
HOW IT WORKS
1. Point your camera at the bill — photo or PDF, medical bill, EOB, denial, or collection notice.
2. We read every line and flag what doesn't add up: duplicates, upcoding, unbundled charges, unverified fees — each one matched to the law that makes them answer.
3. We draft your dispute letter in about a minute and send it USPS certified — a paper trail that demands a written response.
YOUR ANALYSIS IS FREE TO READ — BEFORE ANY ACCOUNT
Scan first. See what we found. Create a free account only when you want to save your case and send the letter. No card to start.
THE LAW IS ON YOUR SIDE
- FDCPA §1692g — collectors must validate the debt in writing or stop collecting
- No Surprises Act — surprise out-of-network bills are often not owed
- Your itemization rights — every charge, in writing, or it can't collect
WE NEVER TAKE A CUT
Billing advocates typically take a percentage of what they recover. Attorneys bill by the hour. BillFighter takes $0 of your winnings — free for 5 analyses a month, Pro $24.99/month with one certified letter included, $9.99 per extra letter. That's everything.
También en español — the whole app, both languages.
BillFighter is not a law firm and does not provide legal advice. AI analysis can make mistakes — review findings before sending.

Evidence vault: every certified letter now shows its mailed date, USPS tracking, and delivery proof right on your case.
Clearer deadlines: once your letter is out, your case shows the collector's response deadline — not yours.
New plans: BillFighter Plus (unlimited bill analysis) and a yearly Pro option.
Bug fixes and performance improvements.
