Same procedure, same date, same amount, billed twice. Worth asking them to confirm.

What they told us

Something is unclear or looks wrong

What we recommended

Billing Error Dispute

The bill has charge-level detail and something specific does not hold up, which is enough to raise it directly.

A suggestion, not a verdict — they can pick a different request before anything is generated.

What happens to your bill

  1. 01Upload

    Your bill is sent over an encrypted connection. No account, no profile, no saved bill history.

  2. 02Process

    Your bill is processed only to create your review and documents, through infrastructure covered by a HIPAA Business Associate Agreement. Those processors may hold inputs briefly under their own contractual retention terms.

  3. 03Download

    Your Action Packet is delivered as downloadable PDFs, with a private re-download link available during the retention window.

  4. 04Delete

    Your bill and generated documents are automatically deleted from TestMyBill’s systems within 24 hours. You do not need to request deletion.

  1. 01

    You upload the bill

    You

    Upload a photo or PDF, including multi-page bills. No account or signup required. If you do not have a readable copy, you can enter the key details manually.

  2. 02

    We review it and flag what stands out

    Us

    We look for duplicates, quantity and total mismatches, and other charges worth reviewing. Each finding is labeled by how strongly the bill itself supports it, so you can distinguish a clear inconsistency from something that simply deserves clarification.

  3. 03

    We recommend the right request

    Us

    A duplicate charge needs a different response than an unaffordable balance or a denied claim. Tell us what happened in plain language, and we’ll recommend the request that best fits your situation — with a short explanation of why. You can choose a different path if needed.

  4. 04

    You answer a few questions

    You

    We ask only for the details needed to personalize your response — your situation, the amount in question, and relevant context. Usually about two minutes.

  5. 05

    You download the packet and use it

    You

    Your packet includes a personalized letter, phone script, call checklist, responses to common pushback, and a follow-up email. Review or edit them before use, then send or use them yourself. TestMyBill never contacts your provider on your behalf.

What happened with your bill?

Choose the situation that fits. We'll show you the request we'd most likely recommend — and why.

Likely first step

Itemized bill request

The bill is summarised, so there is not yet enough detail to say anything is wrong. Asks for the line-by-line record.

See a sample of this letter →

This is a starting point, not a determination. Your actual recommendation comes from your specific bill and the questions we ask before writing anything. Not sure where you stand yet? Read the seven mistakes people make before paying a medical bill.

Five situations, with a different response for each

Not every medical bill problem calls for the same request. A questionable charge, an insurance denial, an unaffordable balance, a payment problem, and no problem at all — just wanting the bill checked — each call for a different approach.

Choose the situation that best matches yours. TestMyBill helps identify a reasonable starting point and prepares the documents and call materials for that path.

Where TestMyBill fits

A general chatbot can help you think through a bill. A full-service advocate can take over the process and contact providers or insurers on your behalf.

TestMyBill sits in between: we help you understand the situation, prepare a practical response, and give you the materials to handle the next step yourself for a fixed price.

We also tell you when TestMyBill may not be the right tool and when a nonprofit, government process, attorney, or professional advocate may be a better fit.

What we won't promise you

Medical billing is a field where confident-sounding claims are cheap. Here is what we deliberately don't say, and what we'll put in writing instead.

We won’t tell you 80% of bills contain errors.

That figure circulates widely without a solid, current source behind it. We tell you what your bill actually shows.

We won’t promise you’ll save thousands based on a guess.

The outcome depends on your provider, your insurer, and your situation — none of which we control. Anyone quoting you an average is guessing.

We won’t call something confirmed unless your bill proves it.

Every finding is labeled by how strongly the bill itself supports it — a provable arithmetic mismatch is not treated the same as something that merely deserves a question.

We won’t make you create an account.

No login, no saved health profile, no ongoing record tying your bill to your identity.

What we do commit to

  • Your bill and generated documents are deleted from our systems within 24 hours — automatically, not on request.
  • Processing runs through services covered by a HIPAA Business Associate Agreement.
  • Your medical information is never sold and never used for advertising. Our AI processor is contractually prohibited from using it to train models.
  • One $19 payment. No subscription, no upsell, no percentage of what you save.

These are the terms we operate under, not marketing language. They're spelled out in our Terms of Service and Privacy Policy.

When TestMyBill is the right tool

  • A hospital, clinic, lab, imaging, or physician-group bill you can upload or describe
  • You want to dispute, appeal, negotiate, or apply for assistance in writing
  • You are willing to send the letter and make the call yourself
  • You want it handled now rather than opening a weeks-long case with someone

When you need someone else

You are being sued, or a judgment or wage garnishment is involved
A consumer-protection or debt-defense attorney. Legal deadlines apply and a letter will not preserve your rights.
Medicare, Medicaid, VA, or workers’ compensation
Those programs run their own appeal processes with their own forms and deadlines. Start with the plan or agency directly.
You want someone to take the case off your hands entirely
A patient advocate or medical-billing advocate. They negotiate for you and typically charge a percentage of what they save.
You suspect fraud, or the provider will not respond at all
Your state insurance commissioner or attorney general’s consumer division. Both accept complaints and have leverage we do not.

Questions people ask

Still unsure? See our frequently asked questions.

Does this guarantee my bill will be reduced?

No. We help you put a clear, professional request in writing. What happens after that depends on your provider and situation. We can't promise any particular outcome, but hospitals do work with patients regularly — many people just never ask.

Is this legal or medical advice?

No. TestMyBill helps you prepare letters and scripts to send to your provider or insurer. It is not legal, medical, or financial advice. For anything complex, talk to a patient advocate or attorney.

Why not just use ChatGPT, Claude, or Gemini for this?

You can — but you'd still have to figure out what to ask for, review the bill yourself, and turn a chat reply into something you can actually send. And your medical bill is sensitive health and billing information: how a general-purpose chatbot stores, reviews, or trains on what you paste depends on the product, your plan, and your settings.

TestMyBill is built for exactly one job, and its protections are fixed by contract rather than left to your settings: your bill is processed exclusively through HIPAA Business Associate Agreement-covered infrastructure, is never used to train any AI model (our AI processor is contractually prohibited from doing so), is never sold or used for marketing, and is automatically and permanently deleted from our systems within 24 hours (the processors that handle it may hold inputs briefly under their own contractual retention terms).

You also get a complete deliverable — a bill review with flagged issues, a send-ready letter for your exact situation, and a matching phone script with objection handling — not a chat transcript.

What happens to my bill and medical information?

Your bill is only used to create your documents. It's processed through services covered by a Business Associate Agreement and deleted from our systems within 24 hours. Those processors may hold inputs briefly under their own contractual retention terms. We never sell your information or use it for marketing.

What kinds of bills does this work with?

TestMyBill works best with bills from U.S. hospitals, clinics, physician groups, labs, and imaging centers — itemized or summary, uploaded as a PDF or photos.

If all you have is an EOB (Explanation of Benefits) from your insurer, that's a statement, not a bill — to get the actual bill, call the provider's billing office with your date of service and account or claim number (both are on the EOB) and ask them to send an itemized bill; they're routinely requested and usually arrive within a couple of weeks. If your claim was denied, keep the EOB handy for an insurance appeal — the denial reason, claim number, and amounts it needs live on the EOB itself, but you'll enter those manually rather than upload the EOB (we don't accept EOBs or denial letters as uploads, since neither is a bill; upload lets you know and points you to manual entry).

Medicare, Medicaid, VA, and workers'-comp disputes run through their own government processes that our letters don't target. Dental, vision, ambulance, and collections balances generally do work — hardship, payment-plan, settlement, and collection-hold requests apply to most provider bills. And if we can't read your document, you can always enter the details manually.

What if I don't have a copy of my bill?

You can enter your billing details manually — just provider name, amount, and a few key details. Many of our letter types don't require a full bill copy.

What does the $19 cover?

Your bill review is free — you see every finding, labeled by how strongly your bill supports it, before you pay anything. The $19 covers the documents that act on it: a personalized letter, a matching phone script with a call checklist, prepared responses to common pushback, a form for logging the call, and a follow-up email template. Everything downloads as a PDF. One-time payment, no subscription.

Why is there a phone script and not just a letter?

Because most of this gets handled by phone. In one study of people who contacted a billing office about a problem bill, about 87% did it by phone rather than in writing (JAMA Health Forum, 2024). A letter is the right paper trail, but if you end up calling — and most people do — you want to know what to say, what to ask, and how to answer when they push back. That is what the Call Kit is for.

Will the hospital or insurer know I used AI?

TestMyBill does not label your letter as AI-generated. Your documents are written as patient correspondence, using the information you provide, and reference the actual billing processes, standard rights, and specific details from your bill. You review everything before you send it.

One bill. One payment. A clear next step.

No account. No subscription. No percentage of any savings.

Your packet is yours to keep, and your bill and generated documents are deleted from TestMyBill’s systems within 24 hours.
