About this app

FairBill checks your medical bills and insurance claims line by line, with exact math, on your own phone.

WHAT IT CHECKS
• EOB payment reconciliation: verifies that the allowed amount equals deductible + copay + coinsurance + plan paid, and that totals match the sum of the lines.
• Duplicate detection: catches the same procedure billed twice on one claim, and the same service billed across two different claims.
• Unbundling and upcoding checks: flags lab panel components billed alongside the panel, incompatible code pairs, and over-used high-level visit codes.
• Improper-charge detection: quality-tracking codes that must always be billed at $0 are flagged when they carry a charge.
• Fair-price benchmarks: compares charges against insurer-negotiated rates and national code ranges. When no verified benchmark exists for a code, FairBill says so instead of guessing.

GETTING YOUR BILLS IN
• Import the claim or EOB PDF from your insurer's portal
• Paste the Claim Details table straight from your insurer's website
• Scan a paper bill with your camera, using on-device text recognition
• Or enter CPT/HCPCS codes and amounts by hand for a quick benchmark check

STAY ON TOP OF YOUR PLAN
• Deductible and out-of-pocket tracker that updates with every audited claim
• Plan-mismatch alerts when a claim was processed at the wrong coinsurance rate
• Generate a formal dispute letter, mark it sent, and get a reminder before the 180-day appeal window closes
• Audit history with status and the savings you actually recovered

PRIVACY BY DESIGN
The audit engine, text recognition and PDF reading all run locally. Your bills, claims, plan details and history stay on your phone. There is no FairBill server holding your medical data. An optional cloud analysis mode (Google Gemini) is available for unusual bill formats; it is clearly labelled, off by default, and chosen by you for each audit.

HONEST BY DEFAULT
If part of a bill cannot be read, FairBill tells you the audit may be incomplete rather than inventing numbers.

FairBill is an informational tool. It is not a substitute for guidance from your provider's billing office, your insurer, or a professional patient advocate, and it does not provide legal, medical or financial advice.
Audit medical bills and EOBs, catch billing errors, and dispute overcharges.
