Lysco is your health advocate. We help Americans review insurance denials, catch billing errors, and understand their options — in seconds, not months.
Our mission
Most Americans never challenge a confusing bill or denial, even when options exist. We make the first review take 30 seconds.

What Lysco does
Read. Analyze. Letter. Done.
Lysco reads your documents, understands the laws that protect you, and drafts the letter you need — in under a minute.
Reads your documents
Upload a photo or PDF of your denial, medical bill, or EOB. Lysco extracts what matters — insurer, codes, amounts, deadlines — with high-accuracy vision.
Finds the weaknesses
Your document is analyzed against the laws and plan rules that apply to your situation. If the insurer got it wrong, Lysco finds it and cites the specific violation.
Writes your letter
A custom appeal, negotiation, or dispute letter citing the exact statutes and plan language that apply. You review, sign, and send. We tell you where.
How we're different
Not a template. Not a promise.
Insurer-specific, not generic
Every analysis is tailored to your insurance company, your state, and your specific denial type. No mass-produced templates.
Citations you can trust
Every legal reference is verified before you see it. If a finding is uncertain, we label it — with a confidence score.
Honest when the denial is correct
We don't tell you what you want to hear. If a denial appears legally sound, we say so — and suggest what else you can do.
Transparent about what we are
Lysco is an informational tool, not a law firm or licensed advocate. We don't represent you, contact your insurer, or give legal advice. We give you everything you need to advocate for yourself.
Built for the American healthcare system
Lysco specializes in US healthcare law and regulations. Every analysis draws on the federal and state rules that actually apply to your case.
- Federal: ACA, ERISA, No Surprises Act, MHPAEA
- State-specific insurance regulations and appeal procedures
- Medicare and Medicaid appeal processes
- Balance-billing protections by state
Laws change frequently. Lysco stays current, but we recommend verifying all legal citations independently before relying on them.
