About BillCheck
The Problem We Solve
Up to 80% of medical bills contain errors — duplicate charges, upcoding, unbundling, balance billing violations, and simple math mistakes. Most patients do not know how to find them.
Traditional billing advocates charge 25–35% of whatever they save you. On a $10,000 bill with $3,000 in errors, that is $750–$1,050 just to learn you were overcharged.
BillCheck does it for $49.
How It Works
BillCheck is an AI-powered medical bill review service. You pay a flat fee, upload your bill, and receive a plain-English report explaining every error found and exactly what to say when you call to dispute.
No jargon, no percentage cuts, no hidden fees.
Built on Three Pillars
Every Lonia AI product is built on three non-negotiable pillars from the first line of code:
Accessibility
WCAG 2.2 AA and Section 508 compliance. Built for the 25% of U.S. adults living with a disability.
Compliance
HIPAA-aware data handling, audit trails, AI provenance tracking, 7-day auto-delete on uploaded files.
Security
OAuth-only authentication, encrypted storage at rest and in transit, private storage buckets, zero password storage.

Founder
Founded by Mary Leriche: with over a decade of experience spanning healthcare operations, medical billing, graphic design, and software development. She's worked both sides of the healthcare system — from patient care to corporate billing offices — and built BillCheck because she saw firsthand how often patients get overcharged, and how few can afford the advocates who find the errors. She built BillCheck because billing advocates charge 25–35% of savings found, and most patients can't afford that. A $49 flat-fee review puts the same analysis within reach.
