What Is Out-of-Network
An out-of-network provider is a doctor, hospital, or medical facility that has no contracted agreement with your insurance plan. When you receive care from an out-of-network provider, your insurer pays a smaller percentage of the bill, and you're responsible for a larger share. The provider also isn't bound by your plan's negotiated rates, which can result in much higher bills.
Out-of-network situations create serious financial risk because two separate fees apply to your care. Your insurance company calculates its "allowed amount" (what they'll pay based on their internal fee schedules), and the provider can bill you for the difference between that allowed amount and their actual charge. This difference is called balance billing, and it's one of the primary reasons patients appeal denied claims or dispute medical bills.
How Costs Differ from In-Network Care
The financial impact is substantial. If you see an in-network provider, your insurance negotiates rates directly. For example, a hospital might charge $5,000 for an MRI, but your insurer's negotiated rate is $1,200. You pay your deductible and coinsurance on that $1,200. With an out-of-network provider, your insurer might only allow $1,200, but the provider charges $5,000. You could owe $3,800 after insurance pays their portion, depending on your plan's out-of-network benefits.
Many plans cover out-of-network care at 60 to 70 percent versus 80 to 90 percent for in-network. Your out-of-pocket maximum is often significantly higher for out-of-network claims as well. Some plans separate in-network and out-of-network deductibles entirely, meaning you may hit two separate deductibles in a single year.
When Out-of-Network Care Occurs
- Emergency situations: You're admitted to an out-of-network emergency room, or emergency specialists treating you at an in-network hospital are themselves out-of-network (called "surprise billing").
- Specialty referrals: Your in-network primary care doctor refers you to a specialist who doesn't contract with your plan, but no in-network alternative exists locally.
- Prior authorization denial: Your insurer denies prior authorization for an in-network provider, forcing you to either go out-of-network or delay care.
- Elective choices: You intentionally seek care from a provider outside your network because of their expertise or reputation.
Out-of-Network Claims and Insurance Appeals
Out-of-network claims are frequently denied or underpaid, triggering appeals. When you receive an EOB (Explanation of Benefits) showing an out-of-network claim paid at a lower rate than expected, you have the right to file an internal appeal within 180 days. If the insurer denies your internal appeal, you can escalate to an external appeal, which involves an independent review organization. Your state's insurance commissioner may also investigate if balance billing violates state law.
Many states regulate surprise billing specifically. New York, for example, prohibits balance billing for emergency services and requires insurers to pay out-of-network providers at in-network rates during emergency care. Federal law similarly protects you from surprise billing at in-network facilities when out-of-network clinicians treat you without your knowledge.
Medical Necessity as a Denial Reason
Insurers sometimes deny out-of-network claims by arguing the care wasn't medically necessary. If you traveled out-of-state for treatment or saw an out-of-network specialist without prior authorization, your insurer may claim they could have covered an in-network alternative. When appealing these denials, you'll need clinical documentation showing why the specific out-of-network provider was necessary. For rare conditions or specialized procedures, this argument is stronger and more likely to succeed in both internal and external appeals.
Common Questions
- Can I be balance billed for out-of-network emergency care? It depends on your state and the situation. Federal law prohibits surprise billing when you receive emergency care at an in-network facility but are treated by out-of-network staff, if the provider didn't give you notice and an opportunity to choose an in-network alternative. Check your state's specific protections, as many states offer broader safeguards than federal law requires.
- If I need prior authorization for an out-of-network provider, how do I submit it? Contact your insurer before receiving care and ask if they'll provide prior authorization. Get the authorization number in writing. Without it, your claim denial is harder to appeal successfully, though you can still try to argue medical necessity. If the insurer denies prior authorization, ask for the specific clinical reason in writing, which becomes evidence for your appeal.
- What should my EOB show for out-of-network claims? Your EOB should list the provider's charge, the insurer's allowed amount, their payment, and your responsibility. If the "patient responsibility" line includes the provider's balance billing amount, your EOB is incorrectly calculated. This is grounds for an immediate appeal claiming billing error.
