Got a Surprise Medical Bill? When the No Surprises Act Protects You

A fictional out-of-network anesthesia bill marked SAMPLE, with the in-network hospital, out-of-network provider and balance due highlighted.


 Got a big bill from a doctor or hospital you didn't choose? A federal law called the No Surprises Act may mean you don't owe it. Here's when it applies and what to do.

What the law covers

The No Surprises Act protects people with job-based, Marketplace, and other private health plans. Medicare and Medicaid have their own billing protections. These are the main protections, according to CMS (CMS: No Surprises Act protections):

  • Emergency care. Out-of-network emergency care generally can't be billed above what you'd pay in network. Your plan also can't make you get approval first for emergency care.
  • Out-of-network doctors at an in-network hospital. For most non-emergency care at an in-network hospital or surgery center, an out-of-network doctor, like an anesthesiologist, generally can't bill you more than your in-network share. For some planned care, a provider can ask you to sign a consent form giving up this protection. That's never allowed for emergency care before you're stable, or for anesthesiologists, radiologists, pathologists, and assistant surgeons. After you're stable, a hospital can ask you to sign one only in limited cases, such as when you could safely travel to an in-network hospital. You never have to sign it.
  • Air ambulance. Covered helicopter and airplane ambulance services are protected too. Ground ambulances are not.

If you don't have insurance

If you're uninsured or paying on your own, providers have to give you a good faith estimate when you schedule care at least 3 business days ahead, or when you ask. If your bill ends up at least $400 more than the estimate, you may be able to dispute it. (CMS) Keep that estimate.

What to do with a surprise bill

  1. Don't pay it yet.
  2. Compare it to your Explanation of Benefits from your insurance.
  3. Call the billing office. Tell them you think the No Surprises Act applies, and ask them to rebill you at your in-network amount.
  4. If they won't fix it, call the No Surprises Help Desk at 1-800-985-3059. You can also contact your state insurance department. (CMS)

Keep notes on every call, with the date and the name of the person you spoke with.

If insurance is the problem

Sometimes the bill is high because your insurance denied the claim. Then you'll need to appeal the denial. The Insurance Denial Appeal Kit has letters for that, including one to dispute a surprise out-of-network bill.

For any bill that looks wrong

The Medical Bill Check Kit helps you check a bill against your EOB, dispute errors in writing, and keep track of every call. It has 7 letters, an 8-page guide, and a bill tracker.

Inpatient or observation? What to ask during a Medicare hospital stay

Last reviewed: November 2026 You can spend the night in a hospital bed, wear the gown, eat the meals, and still not be "admitted." If you have Medicare, that difference can change what you pay and whether Medicare covers rehab in a nursing facility afterward. Here is what to ask, and what to do if your status changes. Inpatient vs. observation, in plain words Inpatient means a doctor wrote an order to formally admit you to the hospital. Observation means you're getting outpatient services while the doctors decide whether you need to be admitted. Medicare.gov puts it plainly: "you're an outpatient even if you spend the night in the hospital." Your status can affect what you pay. Under Original Medicare, an inpatient stay is generally covered under Part A, and observation services are generally covered under Part B, with its own costs for each service. (For a single outpatient hospital service, the copayment can't be more than the inpatient hospital ...

How to list your coding credentials on a resume

When employers are hiring coders, certification often matters. The Bureau of Labor Statistics says employers may prefer it, or require it ( BLS ), and they can look up whether yours is current. So it’s worth getting your credential line right. This is for coders, billers and health information (HIM) staff applying for jobs in the US. Where they go Put your credentials in two places: After your name at the top. Abbreviations only, for example Jordan Lee, CPC, CRC . In a Certifications section. Spell each one out, with who issued it and when you earned it. For example: Certified Professional Coder (CPC), AAPC, earned March 2023. Spelling it out helps when the job posting uses the full name instead of the letters, and when the first person reading your resume isn’t a coder. What order to use AHIMA’s guidance goes like this: academic degrees closest to your name, then the general credential like RHIA or RHIT, then specialty and coding credentials. ( AHIMA ) So it’s Jordan Lee,...

How to Appeal a Health Insurance Denial, Step by Step

 Got a denial letter from your health insurance? You can appeal it, and here is how to do it step by step, with the deadlines that matter. Most people never appeal. In HealthCare.gov plans in 2024, insurers denied 19% of in-network claims, and fewer than 1% of those denials were appealed. ( KFF ) Some people don't know they can appeal. Others are sick, worn out, or out of time. These steps are meant to make it shorter. Who these steps are for: job-based plans and plans you buy yourself, like HealthCare.gov or state marketplace plans. Medicare, Medicare Advantage and Medicaid have their own appeal steps and deadlines. If you have one of those, follow the deadline on your notice, and see Who will help me for free? for the right place to call. A few older "grandfathered" plans may follow different rules too. Step 1: Read the letter for three things Find the reason for the denial, the claim or service it is about, and your appeal deadline. The reason is the part you will ans...
