What you get
The letter, plus everything you need to send it.
The fastest way to lose momentum is getting a nice-looking draft and still not knowing what to attach, where to send it, or what happens next.
Rules and citations
The draft cites the relevant plan language, ACA/ERISA rights, state protections, Medicare rules, or payer policy where they apply.
Evidence checklist
Lysco tells you what to attach: doctor letters, records, prior-auth history, itemized bills, clinical guidelines, or missing forms.
Self-submission path
Review the letter, sign it yourself, then submit by portal, fax, email, or certified mail. Lysco shows the proof checklist and follow-up windows.
Why Lysco is harder to beat
Denial appeals are only the front door.
A denied claim often connects to a bill, prior auth, surprise charge, debt notice, charity-care application, or drug assistance program. Lysco keeps those paths connected.
- Denials, bills, surprise bills, prior auth, EOBs, medical debt, charity care, drug assistance, and benefits in one account.
- Self-submission guidance with portal, fax, email, and certified-mail steps so the work does not stop at a downloadable template.
- Payer playbooks and denial-code strategies for national insurers, PBMs, Medicare, Medicaid, and major BCBS affiliates.
- Escalation paths for external review, state complaints, CMS complaints, debt validation, and hospital financial assistance.
- Flat pricing with no contingency cut, no percent of savings, and a free first analysis before you decide.

Questions
Clear answers before you upload.
Is Lysco a law firm or medical provider?
No. Lysco is informational software. It helps you understand documents, draft paperwork, and organize next steps. It is not legal, medical, financial, or insurance advice.
Will Lysco send the appeal for me?
No. Lysco prepares the letter and instructions, but you review, sign, and submit everything yourself. That keeps the letter in your voice and avoids Lysco acting as your representative or agent.
Can Lysco guarantee the appeal will win?
No. Appeal outcomes depend on your plan, the denial reason, deadlines, evidence, and applicable law. Lysco focuses on making the strongest paperwork path clear.
What does the free first analysis include?
A document review that identifies the core issue, likely workflow, important deadlines, and whether there is a case worth pursuing. A full case adds the finished letter, a self-submission checklist, proof-of-submission tracking, and escalation support.
