In-network vs out-of-network calculator.

Same procedure, different provider network = wildly different out-of-pocket. The calc shows your bill in both scenarios plus your balance-bill exposure.

Calculator

Your bill — in-network vs out-of-network.

Provider's billed charge ($)

The "chargemaster" sticker price the provider sends to insurance.

In-network allowed amount ($)

The negotiated rate your insurer pays in-network providers.

Out-of-network allowed amount ($)

What insurer pays OON. Often 70-100% of in-network rate. Anything billed above this is "balance bill."

No Surprises Act protections apply?

Yes — ER, ground ambulance excluded, or surprise No — I chose OON knowingly

In-network plan rules

Deductible remaining ($) Coinsurance (%)

Out-of-network plan rules

OON deductible remaining ($)

Often separate from in-network deductible — check your SBC.

OON coinsurance (%)

How OON cost gets bigger

Three things make out-of-network cost more than in-network:

Higher allowed amount — insurers often pay more OON because there's no negotiated discount.
Higher coinsurance percentage — typically 40-50% OON vs 20% in-network. Your share of the allowed amount is bigger.
Balance billing — the OON provider can bill you the difference between their charge and the insurer's allowed amount. This is the wildcard that turns a $4,000 procedure into a $15,000 bill.

When the No Surprises Act protects you

The federal NSA (effective 2022) BANS balance billing in these situations:

Emergency care at any hospital or freestanding ER, in-network or out.
Ground ambulance — wait, that's actually a gap, see below.
Non-emergency care at an in-network hospital by an out-of-network provider (the anesthesiologist scenario).
Air ambulance.

If NSA applies, you only owe your in-network cost-sharing — balance bill above that is illegal. Full NSA guide →

When NSA does NOT protect you

Ground ambulance. Not covered by federal NSA — varies by state.
You choose OON and sign a written consent form acknowledging it.
Cosmetic / non-medically-necessary procedures.

FAQ

Common questions.

Why is the OON allowed amount higher than in-network?

Insurers don't have a negotiated rate with OON providers, so they often base OON allowed amounts on "Usual, Customary, and Reasonable" (UCR) charges or a Medicare percentage — usually higher than the in-network negotiated discount but lower than the chargemaster sticker.

Can I dispute a balance bill?

Yes — if it's an NSA-protected situation, file a complaint at the federal NSA portal (CMS) or your state insurance commissioner. Many balance bills are issued in error or in violation of NSA; reviewing the EOB and pushing back works more often than people expect.

Should I ever go out of network on purpose?

Sometimes — specialized procedures where the in-network options are weaker, or specific surgeons / centers of excellence. If you do, get a written cost estimate from the provider FIRST and check whether your insurer offers a single-case agreement to extend in-network rates.

Does the calc handle PPO out-of-network coverage with no balance billing?

Set the OON allowed amount equal to the charge ($8,000 = $8,000). That removes the balance-bill exposure, and you only owe deductible + coinsurance × charge.
