How do insurance denial appeals work?

Upload your denial letter and Lysco analyzes it, identifies the denial reason, cites applicable laws (ACA, ERISA, state regulations), and generates a customized appeal letter. You review and submit it yourself.

Can Lysco predict my appeal result?

Appeal outcomes vary by plan, facts, and documentation. Public data shows consumers rarely appeal denied claims and many denials involve administrative or plan-design issues. Lysco helps users understand the denial, prepare the paperwork, and decide what to do next; it does not predict results.

Is Lysco a law firm or medical practice?

No. Lysco is an informational tool that helps you understand your rights and options. It is not a law firm, medical practice, or insurance company. For specific legal or medical situations, consult a licensed professional.

How much does Lysco cost?

EOB translation is always free and you get one free document analysis and one free appeal letter. Per case: $29 for a denial appeal, medical bill review, or surprise bill dispute. Or upgrade to Pro ($29/mo) or Annual ($199/year) for unlimited everything across all five pillars including the prior authorization helper. Cancel anytime.

Is my health data secure on Lysco?

Yes. Lysco uses AES-256 encryption at rest, TLS for data in transit, and row-level security so only you can access your data. We never sell your data and follow HIPAA-aligned security practices.
