Billing Protections

What are my surprise medical bill rights in Arizona?

Arizona residents are protected from many unexpected medical bills by federal and state laws. These rules stop providers from billing you extra when you unknowingly receive care from out-of-network doctors, especially in emergencies or at in-network hospitals.

What is Surprise Billing?

Surprise billing, also called balance billing, happens when you get care from a doctor or hospital you thought was covered by your insurance, but they are actually 'out-of-network.' This means they don't have a contract with your health plan. When this happens, the out-of-network provider might send you a bill for the difference between what your insurance paid and what they charged.

This can be especially confusing in two main situations: emergency care, where you can't choose your providers, and non-emergency care at an in-network hospital or facility where an out-of-network doctor (like an anesthesiologist or radiologist) is involved without your knowledge.

Federal Protections: The No Surprises Act

The federal No Surprises Act, which started in 2022, helps protect you from many unexpected medical bills. If you have a group health plan or individual health insurance, this law generally says you only have to pay your in-network cost-sharing (like your deductible, copay, or coinsurance) for certain services. This protection applies in a few key situations:

First, for most emergency services, even if you go to an out-of-network emergency room or get care from an out-of-network provider there. Second, for non-emergency services you get at an in-network hospital or ambulatory surgical center from an out-of-network provider. For example, if you have surgery at an in-network hospital, but the anesthesiologist is out-of-network, you should still be protected.

The law prevents these out-of-network providers from billing you for more than your in-network cost-sharing amount. Your insurance company must pay the out-of-network provider directly.

Arizona's Role in Protecting You

Arizona has its own laws that work alongside the federal No Surprises Act to give residents even more protection. These state laws often cover situations that might not be fully addressed by federal rules, or they might offer an additional layer of help.

Arizona has a process for resolving disputes between patients, providers, and health plans when an unexpected bill arises. This means if you get a bill you think is a surprise bill, there's a way to ask for a review and potentially lower the amount you owe. These state-specific protections and dispute options aim to make sure you're not unfairly burdened by bills you couldn't have prevented.

Who Is (and Isn't) Protected?

The No Surprises Act and Arizona laws cover many situations, but not all. You are generally protected when you receive emergency services, or when you are treated by an out-of-network provider at an in-network hospital or surgical center without your consent.

However, there are some common exclusions. For example, the federal No Surprises Act generally does not cover ground ambulance services. This means if you take an out-of-network ground ambulance, you might still receive a surprise bill. Air ambulance services, on the other hand, are covered by the federal law. Also, if you choose to see an out-of-network provider for non-emergency care and agree in advance to pay the higher costs, these protections may not apply.

What to Do If You Get a Surprise Bill in Arizona

Getting an unexpected medical bill can be stressful, but you have options. Here's a step-by-step guide:

1. **Review Your Bill Carefully:** Look for the services provided, the dates, and the amounts charged. Compare it to your Explanation of Benefits (EOB) from your insurance company.

2. **Contact Your Insurance Company:** Call your health plan using the number on your insurance card. Ask them why the service was billed as out-of-network and if it should be covered under surprise billing protections.

3. **Contact the Provider:** If your insurer can't resolve it, call the billing department of the doctor or hospital. Explain that you believe this is an unexpected bill and ask them to re-bill your insurance correctly or adjust the charge.

4. **Use Federal and State Dispute Processes:** If you can't resolve the bill with your insurer or provider, you can file a complaint. For federal protections under the No Surprises Act, contact the Centers for Medicare & Medicaid Services (CMS). For Arizona-specific protections and mediation, reach out to the Arizona Department of Insurance and Financial Institutions (DIFI). They can help you understand your rights and guide you through the state's dispute process.

5. **Keep Detailed Records:** Document every phone call, including dates, times, names of people you spoke with, and what was discussed. Keep copies of all bills, EOBs, and correspondence.

Frequently asked questions

Does the No Surprises Act cover all medical bills?
No, while the No Surprises Act covers many situations, it doesn't cover everything. For instance, ground ambulance services are often excluded from federal protections, meaning you could still get a surprise bill for them. It primarily focuses on emergency care and out-of-network care at in-network facilities.
What if my doctor didn't tell me they were out-of-network?
That's exactly what surprise billing protections are designed to prevent. If you didn't knowingly choose an out-of-network provider and didn't give your consent to pay higher costs, you should be protected. Your bill should be limited to your in-network cost-sharing amount.
How do I dispute a surprise bill in Arizona?
First, contact your insurance company and the provider's billing department to try and resolve it. If that doesn't work, you can file a complaint with the Arizona Department of Insurance and Financial Institutions (DIFI) for state-specific protections. For federal No Surprises Act issues, you can contact the Centers for Medicare & Medicaid Services (CMS).
Can I still choose an out-of-network provider?
Yes, you can still choose to see an out-of-network provider for non-emergency services. However, for the No Surprises Act protections not to apply, the provider must give you a specific notice and get your written consent to be billed for the higher out-of-network costs before you receive the service.
