billcheck

Find the errors hiding in your hospital bill — and a letter to dispute them.

Paste your itemized hospital bill. billcheck reviews it line by line and flags the recognizable billing-error patterns — duplicate charges, lab-panel unbundling, quantity anomalies, math errors, care-setting mismatches — where every flag quotes a real line from your own bill. See a free preview, then unlock the full audit and a send-it-yourself dispute letter for a flat $29.

Paste the itemized bill (with codes and charges), not a one-line summary. Every flag will quote a line from your own bill.

Helps catch charges that don't match where you were seen (e.g. a telehealth fee on an in-person visit).

Why it’s shaped this way

Reviewers and journalists have reported that a large share of medical bills contain errors (Medical Billing Advocates of America, via Marshall Allen’s reporting). billcheck doesn’t promise a dollar outcome — it shows you exactly what to question.

Your bill data

We use your bill text only to run the audit and draft the letter, then clear the raw bill from the active order once the PDF is rendered. See our privacy policy.

billcheck is an automated document-preparation tool. It is not a law firm and does not provide legal or medical advice. You are always the author and sender of any dispute letter, and billcheck never promises a reduction or any outcome.
