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?
