In-network means a doctor, hospital, pharmacy, laboratory, or other health care provider has a contract with your health insurance plan to provide services under negotiated terms. Out-of-network means the provider does not have that contract with your plan. In-network care generally costs you less. Out-of-network care can cost substantially more, may have different deductibles and coinsurance, or may not be covered at all depending on your plan, although federal protections apply to many emergency services and certain unexpected out-of-network services.
Key Takeaways
- In-network providers contract with your health plan and generally result in lower member costs.
- Out-of-network providers do not have a contract with your plan, so your cost can be higher or the service may not be covered.
- PPO plans commonly provide some out-of-network coverage, while HMOs and EPOs generally restrict non-emergency coverage to their networks.
- Federal No Surprises Act protections limit many unexpected out-of-network bills for emergency care and certain services received at in-network facilities.
- Always verify the network status of both the facility and the individual providers involved in planned care when network participation matters.
What Is a Health Insurance Network?
A health insurance network is the group of health care facilities, professionals, pharmacies, suppliers, and other providers that have contracted with an insurance company or health plan to provide services to plan members.
A network can include:
- Primary care physicians.
- Specialists.
- Hospitals and outpatient facilities.
- Laboratories and imaging centers.
- Mental health professionals.
- Physical therapists and other clinicians.
- Pharmacies.
- Medical equipment suppliers and other health care providers.
Networks can differ even between plans offered by the same insurance company. A physician who participates in one insurer’s PPO network, for example, may not participate in every HMO, EPO, employer, or Marketplace network offered by that insurer.
Do not ask only whether a doctor “accepts” your insurance company. Ask whether the provider is in network for your exact health plan and network name.
What Does In-Network Mean?
An in-network provider has an agreement with your health plan to provide covered services under negotiated payment terms.
Using an in-network provider generally means you receive the plan’s preferred level of coverage. Your deductible, copayment, or coinsurance is usually calculated according to the plan’s in-network rules.
Because the insurer and provider have agreed on payment terms, the provider generally cannot simply charge you the difference between its full standard charge and the plan’s negotiated allowed amount for covered in-network care.
Example of In-Network Care
Suppose a physician normally bills $300 for a service but has agreed to an allowed amount of $180 with your health plan. If the provider is in network, your cost sharing is generally calculated using that negotiated amount according to the plan’s rules rather than the provider’s full billed charge.
This example is hypothetical. Actual negotiated rates and member costs vary by plan and provider.
What Does Out-of-Network Mean?
An out-of-network provider does not have a contract with your health plan to provide services under the plan’s network terms.
What happens when you use that provider depends heavily on your type of health plan.
- The plan may pay a smaller share of the bill.
- You may have higher coinsurance.
- A separate out-of-network deductible may apply.
- Out-of-network spending may follow different out-of-pocket rules.
- The provider may be able to bill more than the insurer’s allowed amount when balance-billing protections do not apply.
- Some plans provide no non-emergency out-of-network coverage at all.
“Out of network” does not simply mean “higher copay.” Depending on the plan, it can mean substantially higher financial responsibility or no plan payment for routine care.
In-Network vs. Out-of-Network at a Glance
| Feature | In-Network | Out-of-Network |
|---|---|---|
| Provider contract | Provider contracts with the plan. | Provider does not contract with the plan. |
| Typical member cost | Generally lower. | Generally higher when covered. |
| Negotiated rate | Contracted payment terms apply. | No network contract with your plan. |
| Deductible | In-network deductible rules apply. | A separate or higher deductible may apply if coverage exists. |
| Balance-billing risk | Generally lower for covered contracted care. | Can exist when federal or state protections do not apply. |
| Coverage availability | Generally covered according to plan benefits. | Varies significantly by plan type and circumstances. |
How PPO, HMO, EPO, and POS Networks Differ
The importance of staying in network depends partly on your health plan type.
| Plan Type | Typical Network Approach | Out-of-Network Care |
|---|---|---|
| PPO | Lower costs when network providers are used. | Generally permitted at additional cost, subject to plan rules. |
| HMO | Generally emphasizes providers who work for or contract with the HMO. | Generally not covered except in emergencies or other applicable exceptions. |
| EPO | Uses an exclusive provider network. | Generally covered only in network except in emergencies. |
| POS | Lower costs for network providers and often uses primary-care referrals. | Depends on plan provisions and usually costs more when available. |
These are general descriptions. Individual plan documents control the actual network, referral, authorization, and cost-sharing rules.
Why Does Out-of-Network Care Usually Cost More?
Your insurance company has negotiated payment arrangements with providers in its network. Those contractual arrangements can limit what participating providers charge for covered care and establish how the insurer and member split the cost.
An out-of-network provider does not have that agreement with your plan. If your policy covers the service, it may use a separate allowed amount and require higher cost sharing.
HealthCare.gov notes that out-of-network coinsurance is usually higher than in-network coinsurance.
Hypothetical Example
Suppose a plan requires 20% coinsurance for an in-network service but 40% coinsurance for covered out-of-network care. The out-of-network service could already cost you more because of the higher percentage, and additional charges may be possible when balance-billing protections do not apply.
These percentages are hypothetical illustrations rather than typical nationwide plan terms.
What Is Balance Billing?
Balance billing can occur when an out-of-network provider bills a patient for the difference between the provider’s billed charge and what the health plan recognizes or pays.
For example, if an out-of-network provider charges more than your insurer’s applicable allowed amount, you might potentially be responsible for some additional amount when balance billing is legally permitted.
Federal and state laws now prohibit many surprise balance bills, but the protections do not apply to every possible out-of-network situation.
What Does the No Surprises Act Protect You From?
The federal No Surprises Act provides protections for people with most employer-sponsored and individual private health coverage in several situations where they may receive unexpected out-of-network care.
Federal protections generally include:
- Most emergency services: qualifying emergency services must generally be covered without requiring prior authorization simply because the provider or facility is out of network.
- Emergency cost sharing: patients generally cannot be charged more than applicable in-network cost sharing for protected emergency services.
- Certain services at in-network facilities: protections can apply when an out-of-network clinician, such as certain ancillary providers, is involved in care at an in-network facility.
- Out-of-network air ambulance services: federal surprise-billing protections apply in qualifying circumstances.
For services protected by these federal rules, qualifying patient cost sharing generally cannot be higher than it would have been for in-network care.
Federal protection does not make every out-of-network service an in-network service. Voluntarily choosing an out-of-network physician for routine care can still result in higher costs or no coverage, depending on your plan.
Are Emergency Services Always Treated as In Network?
For private health coverage subject to the No Surprises Act, most covered emergency services received from an out-of-network provider or facility are subject to federal protections designed to keep the patient’s cost sharing at an in-network level.
That matters because a person experiencing an emergency may have little control over which hospital, emergency physician, anesthesiologist, or other clinician provides care.
Federal protections also generally prohibit requiring prior authorization solely because qualifying emergency care is provided out of network.
Ground Ambulances Are an Important Exception
Federal No Surprises Act protections generally do not apply to ground ambulance services.
CMS states that ground ambulance providers may still be able to charge out-of-network rates unless another law, such as an applicable state rule, provides additional protection.
Air ambulance services are treated differently and can fall under federal No Surprises Act protections.
Can an In-Network Hospital Have Out-of-Network Doctors?
Yes. A hospital’s network status does not automatically mean every physician or other professional working there has the same network relationship with your plan.
For example, a patient can choose an in-network hospital but receive services from an anesthesiologist, radiologist, pathologist, assistant surgeon, or other provider who is out of network.
The No Surprises Act protects patients from many unexpected out-of-network charges in these circumstances, particularly for specified ancillary services at an in-network facility.
For scheduled care, verify both sides of the transaction: check whether the facility is in network and whether the major physicians involved in the procedure participate in your plan when you have a choice.
What Is a Notice and Consent Form?
In some non-emergency situations, an out-of-network provider may give you a notice and consent form explaining that the provider is outside your plan’s network and asking you to agree to receive out-of-network care.
Signing a valid notice and consent form in a situation where waiver is permitted can mean giving up certain federal protections against out-of-network charges and balance billing.
Read the form carefully before signing. It is not simply another routine medical consent document. CMS warns that signing can mean agreeing to give up billing protections and potentially paying more for care.
Does Out-of-Network Spending Count Toward Your Out-of-Pocket Maximum?
Do not assume routine out-of-network spending counts toward the same annual out-of-pocket maximum that applies to in-network care.
Some plans that cover out-of-network services use separate deductibles, coinsurance, or out-of-pocket limits. Other plans may not credit certain out-of-network expenses toward the in-network maximum at all.
Protected services under federal surprise-billing rules are different. When applicable, patient cost sharing for protected services is generally calculated using in-network standards and credited according to the applicable in-network cost-sharing rules.
How to Check Whether a Provider Is In Network
Network information is important enough to verify before planned medical care, particularly when the service could be expensive.
- Identify your exact plan: use the network or plan name shown on your insurance card rather than only the insurance company’s name.
- Check the plan’s provider directory: search for the specific physician, facility, or pharmacy.
- Contact the insurer: confirm network participation when the financial consequences are significant.
- Ask the provider: verify that the office participates in your exact network, not merely that it “takes” the insurance company.
- Check again for major procedures: confirm the hospital, surgeon, and other providers involved when possible.
Provider participation can change. If network status is critical, keeping a record of your verification can also be useful if a billing dispute later arises.
Use the Summary of Benefits and Coverage
The Summary of Benefits and Coverage, or SBC, is a standardized document designed to help consumers understand and compare health plan benefits.
CMS explains that the SBC summarizes important plan features including cost-sharing provisions, covered benefits, limitations, and exceptions.
When evaluating network coverage, use the SBC together with the provider directory and full plan documents to determine:
- Whether non-emergency out-of-network care is covered.
- The in-network deductible.
- Any separate out-of-network deductible.
- In-network and out-of-network coinsurance.
- Referral or authorization requirements.
- Important exclusions and limitations.
A Practical Network Comparison
Consider two hypothetical health plans. The following figures are examples only and do not represent national averages.
| Feature | Plan A | Plan B |
|---|---|---|
| Plan structure | EPO-style network | PPO-style network |
| Monthly premium | $325 | $450 |
| Routine out-of-network coverage | Generally none under the hypothetical plan. | Available with higher hypothetical cost sharing. |
| Preferred specialist | Out of network | In network |
| Main trade-off | Lower premium but more restricted provider choice. | Higher premium but greater provider flexibility. |
If the enrollee is comfortable using Plan A’s network, the lower premium may provide better value. But someone who regularly sees the specialist or wants greater flexibility may consider Plan B’s higher premium worthwhile.
The example demonstrates why network design should be compared alongside premiums, deductibles, prescription coverage, and other plan costs.

Frequently Asked Questions
The Bottom Line
In-network providers have contracts with your health plan, while out-of-network providers do not. That difference can affect the negotiated price, deductible, copayment, coinsurance, out-of-pocket limits, and whether your insurance pays for the service at all.
PPO plans generally offer more flexibility to receive covered out-of-network care at additional cost, while HMO and EPO plans usually place greater restrictions on routine out-of-network services. Your actual policy determines the rules.
Federal No Surprises Act protections can prevent many unexpected out-of-network bills for emergency services and certain services received at in-network facilities, but they do not eliminate every out-of-network charge. Before planned care, verify the provider network carefully and compare both the facility and individual clinicians whenever possible.
