Review Your Bill

The Problem

Medical Bills Are Designed to Confuse You

Up to 80% of medical bills contain errors. The average American cannot decode CPT codes, modifier flags, or balance billing. Traditional billing advocates charge 25–35% of savings found — on a $10,000 bill with $3,000 in errors, that is $750–$1,050 just to find out you were overcharged.

Most people just pay and hope for the best. BillCheck exists so you do not have to.

Trust & Security

Your data is handled with care.

BillCheck is built by Lonia AI — a company founded on three pillars: accessibility, compliance, and security. Every workflow reflects those commitments.

HIPAA-Aware Workflows Encrypted Storage 7-Day Auto-Delete OAuth-Only Audit Trails Zero Password Storage

Compliance

All uploaded files are processed through HIPAA-aware workflows with full audit trails. AI-generated content includes provenance tracking.

Security

Files are stored in Supabase with encryption at rest and in transit. Documents auto-delete after 7 days. We never store passwords — authentication is OAuth-only.

Accessibility

This site and all Lonia AI products meet WCAG 2.2 Level AA and Section 508 standards. Accessibility is a foundational requirement, not a retrofit.

Common Questions

Frequently asked questions

What files do I need to upload?

Your medical bill and your Explanation of Benefits (EOB) from your insurance company. Both are needed for a thorough analysis.

How long does the review take?

Reports are delivered by email within two business days of receiving your uploaded documents.

What happens to my files after the review?

All uploaded documents are automatically deleted from our servers after 7 days. We retain only a minimal record (date, issue count, report summary) for liability purposes.

What's the difference between Basic and Pro?

Basic gives you a full bill breakdown with error flagging and a plain-language report. Pro adds ready-to-send dispute letters for both your provider and insurer, plus prioritized action steps.

Is my data secure?

Yes. Files are encrypted at rest and in transit via Supabase. We use OAuth-only authentication, never store passwords, and auto-delete documents after 7 days.

What if my bill has no errors?

You'll receive a confirmation report verifying everything checks out. Think of it as a second opinion — peace of mind has value.

How is BillCheck different from Themis?

BillCheck is a done-for-you review service — you upload, we analyze, you get a report. Themis is a self-service SaaS platform where you reconcile bills yourself on an ongoing basis. Different tools for different needs.
