How it works

  1. Step 1

    Share your bill

    Start a free scan. Today you can run it on our sample ER bill to see exactly how it works.

  2. Step 2

    We check every line

    We compare each charge against federal billing rules and your Explanation of Benefits to flag what looks wrong.

  3. Step 3

    You get a dispute package

    If you want to push back, we prepare the dispute letters in your name with citations and deadlines — ready to mail.

Don’t have an itemized bill? You can request one — most hospitals provide an itemized bill on request, and many states’ billing laws require it. The complete package includes a letter that asks the hospital for your fully itemized bill, so you can see every charge before you dispute it.

Common medical bill errors we check for

Duplicate charges

The same service or code billed more than once on the same date.

Code pairs that should be bundled

Charges for procedures that Medicare's NCCI coding rules say shouldn't be billed separately.

Upcoding

A more expensive code billed than the care you actually received supports.

EOB-rejected charges

Line items your insurer's Explanation of Benefits did not cover, still billed to you.

Self-pay overcharges

Cash prices billed above the standard charges federal price-transparency rules ask hospitals to post.

Missing financial-assistance discounts

Nonprofit-hospital charity-care discounts you qualified for but were never applied.

Simple, flat pricing

One flat fee. We never take a percentage of what you save. The scan is always free.

Medical bill questions people ask

How do I know if my medical bill is wrong?
Compare your itemized hospital bill line by line against the care you actually received and your insurer's Explanation of Benefits (EOB). Watch for duplicate charges, procedure codes that should be bundled, services you never got, and charges your insurance already denied. Our free AI scan does this automatically in minutes and flags what looks wrong, with a citation for each finding.
What are the most common medical billing errors?
The most common medical billing errors are duplicate charges, unbundled code pairs (procedures billed separately that Medicare NCCI rules say should be billed together), upcoding, charges your EOB already rejected, self-pay overcharges above posted prices, and missing nonprofit financial-assistance (charity care) discounts. We check for all six on every bill.
Can I dispute a hospital bill myself?
Yes. You can request an itemized bill, point out specific errors in writing, and cite the billing rules and state statutes that apply — no lawyer required. IsMyBillWrong prepares those dispute letters in your own name so you can review, sign, and mail them yourself.
How much does it cost?
A flat fee — $49 for the audit, $99 for the complete dispute package, and $19 each for a follow-up letter or an optional complaint to your state regulator. We never take a percentage of what you save. The scan itself is always free.
What if you find nothing?
The scan is free, so you find out at no cost. If your bill checks out, you'll see that clearly and owe nothing. You only pay the flat fee if you decide you want the dispute package.
How long does the scan take?
The free scan runs in minutes. You upload your itemized bill (and your EOB, if you have it) and get a plain-English report of what looks wrong, with citations, before you decide whether you want a dispute package.
Is my data safe?
Yes. Your bill is encrypted, never sold, and never used to train AI. You can delete your case at any time. We keep patient and bill details out of URLs, logs, and analytics.
Is this legal advice?
No. IsMyBillWrong is a document-preparation service. We prepare dispute paperwork in your name based on your bill and public billing rules. We are not a law firm, we are not your attorney, and nothing here is legal advice. For legal advice, talk to a licensed attorney.
