Frequently asked questions
How do I know if my medical bill has errors?
Upload your bill to VerifyDoc. Our AI checks for duplicate charges, upcoding (billing a simple service as complex), unbundling (splitting one procedure into multiple charges), phantom charges, and math errors. Many hospital bills contain errors, so it is worth reviewing yours line by line. VerifyDoc flags anything that looks off and explains why, but it cannot confirm that a charge is actually wrong — always verify with your provider or insurer.
What is upcoding on a medical bill?
Upcoding is when a provider bills for a more expensive service than was actually performed. A common example is billing a brief office visit using a code for an extended one, or coding a routine procedure as complex. It is one of the most common and costly billing errors, and upcoding is one of the things VerifyDoc looks for when it reviews your bill.
What types of medical bills can VerifyDoc audit?
VerifyDoc audits hospital bills, doctor invoices, surgical center bills, lab bills, radiology bills, and Explanations of Benefits (EOBs) from your insurer. Upload as a PDF, take a photo, or paste the text directly.
How do I dispute a medical billing error?
Contact your provider in writing, citing the specific CPT code and the billing guideline it violates. VerifyDoc generates a ready-to-send draft dispute letter for every flagged item, written in clear, professional language that explains the concern so you can send it to your provider or insurer.
Can I download my audit report?
Yes. Every audit produces a downloadable PDF report you can save, print, or attach to a dispute letter. The PDF includes the full line-by-line analysis, flagged items with explanations, and the dispute letters for each flagged charge.
Is VerifyDoc medical or legal advice?
No. VerifyDoc is a document analysis tool. It identifies potential billing discrepancies and explains what medical codes mean — it does not provide medical diagnoses, treatment recommendations, or legal advice. Always consult your provider, insurer, or a qualified medical billing advocate to resolve disputes.
How does the family plan work?
The family plan gives you up to 6 individual member accounts, each with their own email login. The account owner invites members by email from their dashboard. Each member gets a verified account — accounts cannot be shared between two people using the same login. Members can only see their own audit history.
