About Lysco
Healthcare paperwork should not need a lawyer.
We turn confusing medical paperwork into clear answers — and the exact letter to fight back, if it is worth fighting.
Why we built this
The rules say you can fight. Almost no one does.
In the United States, almost one in five in-network claims is denied. Federal law gives you the right to appeal nearly every one of them. But less than one percent of people ever file the paperwork — usually because the paperwork is the hard part, not the case. That is the gap Lysco was built to close.
100 million
Americans are carrying medical debt.
up to 80%
of hospital bills contain at least one billing error.
What you can count on
Four rules we will not break.
We are new, so we have not earned long-term trust yet. What we can do is be specific about how we work — and be the kind of specific you can hold us to.
01
Free first read on every document.
Upload anything from a hospital, doctor, or insurance company and we will read it for free. If the bill looks right, the deadline has passed, or the situation is not worth fighting — we tell you up front. No dollar changes hands until you decide there is a case worth pursuing.
02
Flat $9 per case. Never a percentage.
When you decide to generate the letter, it is nine dollars. Not a cut of what you save. Not a subscription. Not a contingency. If you would rather pay monthly for unlimited everything, Pro is $19 a month. Either way, you know exactly what you owe before you owe it.
03
Your documents never train AI.
We use AI to read and understand your paperwork, but your files never enter a model’s training data. Your name, claim ID, and account numbers are encrypted with rotating keys. Bank-grade protection in transit and at rest. You can delete a case and every file attached to it in one click.
04
You review, sign, and send every letter yourself.
We write the draft, find the right address, build the checklist, and remind you when to follow up. But the final word is always yours. We are informational software — we do not negotiate, file, or represent. This keeps you in control and keeps us honest about what we are.
How it works
Three steps. About a minute.
- 01
Send us the paper.
Photo, PDF, screenshot, or pasted text. Anything that came from a hospital, doctor, or insurance company.
- 02
We read it for free.
Roughly forty-five seconds later, you get a one-page summary: what the document is, what may be wrong, what your rights are, and whether it is worth doing anything about it.
- 03
You leave with the next move.
If there is a case, we draft the letter or form, give you the exact address to send it to, and remind you about the deadline. You sign and send.
Who we are
A small US team. Real people.
Lysco is built by a small team in the United States. We do not have a wall of customer stories yet — we are early. What we do have is a free first read, one flat price, and a real person who reads every email that comes in. Usually back the same day.
If something on Lysco is confusing, or wrong, or could be better — we want to hear from you. Especially if you are using Lysco for a real case and got stuck somewhere. We read every word.
In brief
What Lysco is
Lysco is an American software service that helps consumers review and respond to health-insurance and medical-billing paperwork. Available in the United States only, it covers denied insurance claims, medical bill errors, surprise bills under the federal No Surprises Act, prior-authorization denials, explanation-of-benefits statements, and medical debt.
Users upload a document — such as a denial letter, medical bill, explanation of benefits, or collection notice — which the service analyzes using artificial intelligence to identify the relevant issues, deadlines, and applicable rules, and to draft correspondence such as appeal or dispute letters. Lysco is informational software: it prepares analyses, drafts, and self-service materials that users review, edit, sign, and submit themselves. It does not provide legal or medical advice, and does not represent users or submit, negotiate, or file documents on their behalf.
Lysco operates on a freemium model: an initial document analysis is free, with a flat per-case fee to unlock a complete letter and submission packet, plus monthly and annual subscription options for unlimited use. The company was founded in 2025 and operates at lysco.com.
