I Got a Surprise Medical Bill — What Do I Do?

Don't panic and don't pay immediately. Most surprise bills can be reduced, negotiated, or disputed — and many are illegal. Here's exactly what to do, step by step.

8 Steps to Take Right Now

Follow these in order. Most people resolve their bill by step 6.

1

🛑 Don't pay immediately

Paying a bill before reviewing it can waive your right to dispute it. Take time to verify every charge is accurate and that your insurance processed it correctly.

2

📄 Request an itemized bill

Call the provider and ask for a line-by-line itemized bill. Hospitals are required to provide one. Look for duplicate charges, charges for services you didn't receive, or upcoded procedures.

3

📬 Get your Explanation of Benefits (EOB)

Log into your insurance portal or call them to get your EOB. This shows what your insurer paid, what they denied, and what they say you owe. The EOB and your bill should match.

4

🔍 Check for billing errors

Studies show up to 80% of medical bills contain errors. Look for wrong diagnosis codes (ICD codes), wrong procedure codes (CPT codes), or services billed as out-of-network that should be in-network.

5

📞 Call your insurer first

If your insurer denied or underpaid a claim, call them and ask why. Ask if you can file an appeal. Insurers sometimes deny claims in error — a single call can reverse it.

6

🤝 Negotiate directly with the provider

Providers expect negotiation. Ask for the 'cash pay' or 'self-pay' rate — often 40–60% less than the billed amount. Ask about a payment plan with 0% interest. Nonprofit hospitals are often legally required to offer financial assistance.

7

⚖️ File a formal appeal if needed

If your insurer denied coverage, you have the right to an internal appeal and then an external independent review. Get the denial reason in writing and reference your plan's Summary of Benefits and Coverage.

8

🏛️ Report it if it's illegal

Under the No Surprises Act (2022), emergency care and certain out-of-network charges at in-network facilities are capped. If you were balance billed illegally, report it to CMS at cms.gov/nosurprises.

Common Billing Errors to Look For

When reviewing your itemized bill, watch for these red flags.

Error TypeWhat It Means
Duplicate chargesSame service billed twice — common with lab tests and medication
UpcodingA basic office visit billed as a complex one to charge more
UnbundlingProcedures that should be billed together are split to inflate the total
Wrong patient infoWrong DOB or insurance ID can cause claim rejection
Out-of-network listed incorrectlyIn-network provider billed as out-of-network
Services not renderedCharged for consultations or tests that didn't happen

Your Legal Rights as a Patient

No Surprises Act (2022)

Emergency services at any hospital must be billed at in-network rates, even if the hospital is out-of-network. You cannot be balance billed for emergency care.

Right to an itemized bill

Every patient has the right to request a detailed itemized bill from any healthcare provider. They must provide it.

Right to appeal

If your insurer denies a claim, you have the right to an internal appeal and then an external independent review by a third party.

Hospital financial assistance

Nonprofit hospitals that accept Medicare/Medicaid must offer charity care or financial assistance programs to qualifying patients. Always ask.

Good Faith Estimate

If you're uninsured or self-pay, providers must give you a Good Faith Estimate of costs before scheduled services under the No Surprises Act.

What to Say When You Call

Use this script when calling your provider's billing department:

"Hi, I received a bill for [amount] dated [date]. I'd like to request an itemized bill showing each service and its CPT code. I also want to understand my financial assistance options and whether there is a self-pay or cash-pay rate available. Can you help me with that?"

Always write down the name of the person you spoke with, the date, and what was agreed to.
