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.

What is the success rate for insurance appeals?

It varies by plan type. For ACA marketplace plans, about 44% of appealed denials are overturned (KFF, 2023). For Medicare Advantage, it can be as high as 83% (HHS OIG). Many denials stem from billing or administrative errors that get fixed when challenged. Individual results vary.

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?

Analysis is always free and your first appeal letter is free too. Upgrade to Pro ($29/mo) or Annual ($199/year) for unlimited appeal letters, deeper insurer-tailored analysis, and benefits finder. 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.
