## What is BillFighter?

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.

After having my son, I was overwhelmed with medical bills. This app was a lifesaver. It alerted me to some issues with my insurance coverage (or lack there of) and provided the steps for me to follow. It can also help you create a dispute letter, making the process very easy. This app helped me save thousands.
