Sample audit
St. Mercy Regional — ER visit, March 12

Bottom line

Total billed: $7,510. We found ~$1,840 in disputable charges across three line items. Recommend disputing before paying.

Suspicious charges

  • Upcoded ER visit — $1,280. Billed at the highest "life-threatening" tier. Documented symptoms suggest a less severe level. Ask for a re-code.
  • Duplicate lab — $340. The same blood-work charge appears twice on the same date. Ask them to remove one.
  • IV saline marked up far above standard rate — $220. The bag of saline is billed at roughly 12× the typical reimbursement. Ask them to adjust to a fair rate.

Re: Account #4421-093 · Date of service March 12

Dear Billing Department,

I am formally disputing the following charges on the above-referenced account:

  1. ER visit billed at highest tier — $3,420. The documented presentation does not meet the criteria for that level. Please re-code to the level that matches the visit.
  2. Duplicate basic blood-work charge — $340. The same line item appears twice on the same date. Please remove the duplicate.
  3. IV saline at significant markup — $268. Far above standard reimbursement. Please adjust to a fair rate.

Per the Fair Debt Collection Practices Act, please do not refer this account to collections while this dispute is pending. I expect a corrected statement within 30 days.

Sincerely, [Your Name]

Common questions.

Will this guarantee the hospital gives me money back?＋
No. Nothing can guarantee that. What we guarantee is a clear audit and a well-formed dispute letter — most of the work people hire human billing advocates for. If our audit doesn't produce actionable findings, we refund you within 7 days, no questions asked.
What if my bill isn't itemized?＋
Most aren't. We have a free tool that writes the letter to request the fully itemized bill from the hospital. They typically respond within 30 days.
I only have a phone photo of my bill — does that work?＋
Yes. Upload it as a JPG or PNG. Our auditor uses image vision to read line items directly off the photo.
Is my bill data safe?＋
Bill content is held in your browser until you pay. After payment it's processed once and not retained on our infrastructure. See our privacy policy.
