Balance Billing
Balance billing is when a provider bills you for the part of a charge your health insurance plan did not pay. This can happen when the provider’s price is higher than your insurance plan’s allowed amount. It usually comes up with out-of-network care. The extra bill is the difference between what the provider charged and what your insurance plan agreed to cover.

Key Takeaways
- Balance billing is the amount a provider bills after your insurance plan has paid its share.
- It most often happens when you receive care from an out-of-network provider.
- The cost to you is the difference between the provider’s charge and the insurance plan’s allowed amount.
- Federal or state protections may limit balance billing for some emergency services and certain care at in-network facilities.
- Checking that a provider is in-network before receiving care can help you avoid unexpected medical bills.
What is Balance Billing?
Balance billing happens when a provider charges you for the difference between the full bill and the amount your health plan recognizes for payment. This usually comes up with out-of-network care.
For in-network care, providers usually agree to set rates with the plan, so balance billing is less likely to apply. With out-of-network care, the provider may charge more than your plan’s allowed amount. If that happens, you may get a bill for the difference in cost. Balance billing can lead to higher costs than expected, which is why it is important to check your network before you get care.
Things to Know About Balance Billing
- What is surprise billing? Surprise billing is an unexpected charge you receive when you unknowingly get care from an out-of-network provider, often during emergencies or at an in-network facility.
- Why does balance billing occur? It happens when a provider charges more than your insurance plan’s allowed amount and is not required to accept that rate, which is common with out-of-network care.
- How can you avoid it? You can lower your risk by choosing in-network providers, confirming network status before care, and asking about costs in advance.
- What are the consequences? Balance billing can lead to higher out-of-pocket costs and unexpected medical bills that are not always counted toward your out-of-pocket maximum.
How This Shows Up in Real Life
Let’s say you get care from an out-of-network provider. The provider charges $250 for the visit. Your plan’s allowed amount is $140. The provider may bill you for the extra $110. That extra charge is balance billing.
Service Cost Example | Amount |
|---|---|
Provider bill | $250 |
Allowed amount | $140 |
Difference | $110 |
Possible balance bill | $110 |
How Balance Billing Affects What You Pay
Balance billing can raise your out-of-pocket costs fast. You may owe your normal cost sharing and then get an extra bill from the provider. That can make a service cost much more than you expected.This is one reason in-network care usually costs less and is easier to plan for. Federal protections may limit balance billing for some emergency services and some care at in-network facilities. Even so, it is smart to check provider network status before you make an appointment.
Where to Find This in Your Plan Details
To check how your plan handles out-of-network care and billing, you can look at:
- Your Summary of Benefits and Coverage (SBC)
- Your Explanation of Benefits (EOB)
- Your Schedule of Benefits
- Your member handbook or policy documents
- Your Ambetter Health online member account
These resources can help you check out-of-network rules, allowed amounts, and cost sharing.
How This Changes Across Marketplace Plans
Balance billing risk can be different across Marketplace plans. One reason is how each plan handles care outside its provider network. Some plans cover little or no out-of-network care. Others may cover some services but at a higher cost. These differences can affect how likely balance billing is and how much you may have to pay.
- Insurance plans with little out-of-network coverage may leave you with more of the bill.
- Different network types can change how likely balance billing is.
- Emergency protections may lower your risk in some cases.
- It is always a good idea to check your insurance plan before receiving care.

| Allowed Amount Rules | Insurance plans can set different allowed amounts for the same service | The gap between the bill and plan payment can be different |
| Emergency Care Protections | Some services have federal billing protections | You may have fewer surprise bills in protected situations |
FAQs About Balance Billing
No. Coinsurance is your share of the cost for a covered service under your health plan’s rules. Balance billing is different. It is an extra charge from a provider when their price is higher than the amount your health plan allows for the service. Balance billing is generally not applied to your deductibles or out-of-pocket maximums for in-network benefits.
Usually not. In-network providers agree to set payment rates with your health plan, which means they typically cannot bill you for more than the allowed amount. However, some situations can be more complex, such as when part of your care involves an out-of-network specialist or provider.
Most balance billing happens when you receive care from an out-of-network provider. In those cases, the provider may charge more than your plan’s allowed amount and bill you for the difference. Federal law may protect you from balance billing in some emergency situations and certain care at in-network facilities.
One of the best ways to avoid balance billing is to check that your doctor, hospital, lab, or specialist is in-network before you receive care. You can also ask your provider for a cost estimate and review your plan details ahead of time so you understand your coverage and potential costs.
Start by reviewing the bill and comparing it with your insurance plan documents or your explanation of benefits (EOB). Make sure the charges match the services you received and the amount your plan allowed. If something looks wrong or confusing, contact Member Services or the provider’s billing office for help.
