Key Takeaways
Option A
In-Network Care
The contracted, cost-sharing-friendly option.
Best for: Patients who want predictable out-of-pocket costs and full access to their plan's negotiated rates.
Option B
Out-of-Network Care
The unconstrained but potentially costly choice.
Best for: Patients who require a specific provider not in their plan's network, or who have a PPO or POS plan that allows out-of-network benefits.
If you want the most predictable, lowest out-of-pocket costs
In-Network Care
Negotiated rates, lower cost-sharing tiers, and contributions toward your deductible and out-of-pocket maximum all apply when you stay in-network.
If you need a highly specialized provider not in your network
Out-of-Network Care
When no in-network equivalent exists for a required specialist, out-of-network care may be unavoidable — understanding your plan's out-of-network benefits in advance helps limit the financial impact.
If you have an HMO or EPO plan
In-Network Care
HMOs and EPOs typically provide no coverage for out-of-network services outside of emergencies, making staying in-network essential for covered care.
If you have a PPO and value provider flexibility
In-Network Care
Even with a PPO's out-of-network option, in-network care will nearly always cost you significantly less due to lower deductibles and coinsurance rates.
What 'Network' Actually Means in Health Insurance
A provider network is the group of doctors, hospitals, labs, and other health care providers that have signed contracts with your insurance company. Under those contracts, the provider agrees to accept a negotiated rate — a pre-set, discounted price — for covered services. Your insurer, in turn, agrees to steer members toward those providers.
When you see an in-network provider, your insurer applies that negotiated rate, then calculates your share using the cost-sharing terms of your plan — deductible, copay, or coinsurance. The result is a predictable, typically lower bill. When you see an out-of-network provider, no contract exists. The provider can charge their standard rate (often called the billed charge), which may be many times higher than what an insurer would have negotiated.

| Criterion | In-Network Care | Out-of-Network Care |
|---|---|---|
| Provider agreement | Contracted with your insurer | No contract with your insurer |
| Rates applied | Negotiated (discounted) rates | Full billed charges may apply |
| Deductible | Lower; counts toward in-network max | Higher; often tracked separately |
| Coinsurance | Typically 10–30% | Typically 30–50% or more |
| Out-of-pocket maximum | Lower cap; clearly defined | Higher cap or none; balance bills excluded |
| Balance billing risk | None — provider accepts contracted rate | Possible; provider can bill the difference |
| HMO/EPO coverage | Fully covered (per plan terms) | Not covered except emergencies |
| Referral requirements | Varies by plan type | Usually none, but cost is higher |
How Cost-Sharing Differs Between Network Tiers
The financial gap between in-network and out-of-network care is rarely just a matter of one number. Several cost-sharing layers behave differently depending on which tier applies.
Deductibles
Many plans maintain separate deductibles for in-network and out-of-network care. Your out-of-network deductible is typically higher — sometimes two to three times the in-network amount. Dollars you spend out-of-network generally don't count toward your in-network deductible, and vice versa on plans that keep them separate. To understand how deductibles layer with other cost-sharing, see Deductibles, Copays, and Coinsurance.
Coinsurance
After meeting your deductible, you pay a percentage of the allowed amount. In-network coinsurance might be 20%, meaning your insurer covers 80%. Out-of-network coinsurance is often 40–50% — and crucially, it applies to the allowed amount your insurer sets, not necessarily the provider's full charge. The gap between those two numbers is called balance billing.
Out-of-Pocket Maximum
Your out-of-pocket maximum caps total spending, but most plans set a higher cap for out-of-network care — or don't apply one at all. Balance-billed amounts typically don't count toward any cap. Why your out-of-pocket maximum matters explains why this ceiling is one of the most important numbers in your plan.

Emergency visits involving an out-of-network provider
Research published in health policy journals has estimated roughly one in five emergency room visits involves at least one out-of-network clinician, often without the patient's knowledge.

Typical out-of-network vs. in-network deductible ratio
On many PPO plans, the out-of-network deductible is two to three times higher than the in-network deductible, per general plan design patterns documented by benefits analysts.
40–50%
Common out-of-network coinsurance rate
Many employer-sponsored PPO plans apply 40–50% coinsurance to out-of-network services, compared to 20% or less for in-network care, based on widely reported plan benchmarks.
Balance Billing: The Hidden Cost of Going Out of Network
Balance billing occurs when an out-of-network provider charges you the difference between their billed rate and the amount your insurer pays. For example, suppose a provider bills $3,000 for a procedure. Your insurer's allowed amount is $1,200, and they pay 60% of that ($720). You owe your 40% coinsurance ($480) — but the provider can also bill you the remaining $1,800 difference. Your total exposure: $2,280 instead of $480.
Federal protections under the No Surprises Act, which took effect in 2022, limit balance billing in specific situations — primarily emergency care and certain non-emergency care at in-network facilities where you didn't have a meaningful choice of provider (such as anesthesiologists or radiologists). However, these protections do not apply to all out-of-network situations. When you proactively choose an out-of-network provider, balance billing protections generally do not apply.
No Surprises Act: Know Its Limits
The No Surprises Act (effective January 2022) protects patients from unexpected out-of-network bills in emergency settings and from certain providers at in-network facilities — such as anesthesiologists or assistant surgeons — when the patient had no realistic opportunity to choose. However, the law does not protect you when you knowingly and voluntarily schedule care with an out-of-network provider. In that case, balance billing can still apply in full. Some states have additional balance billing protections that may go further than federal law; check your state insurance commissioner's office for details.
Plan Type Determines Your Out-of-Network Exposure
How much out-of-network care costs — or whether it's covered at all — depends heavily on your plan structure. HMO vs. PPO differences go to the heart of this question.
- HMO (Health Maintenance Organization): Out-of-network care is not covered except in genuine emergencies. Using an out-of-network provider intentionally typically means you pay 100% of the bill.
- EPO (Exclusive Provider Organization): Similar to an HMO in that out-of-network care is generally excluded, but you usually don't need referrals for specialists.
- PPO (Preferred Provider Organization): Out-of-network benefits exist, but at significantly higher cost-sharing. You pay more, and separate (higher) deductibles and out-of-pocket maximums often apply.
- POS (Point of Service): A hybrid — requires referrals like an HMO but allows out-of-network access at higher cost like a PPO.
Reviewing your Summary of Benefits and Coverage (SBC) document tells you exactly what your plan covers out-of-network and at what cost-sharing rates.
