The hospital gave me an estimate and the bill is much higher. Can I dispute it?

If you are uninsured, or insured but paying yourself, a provider is required to give you a Good Faith Estimate in writing before a scheduled service.

If a provider's final bill comes in $400 or more above the estimate that provider gave you, you can dispute it through a federal process.

What you should have received

For scheduled care, a written estimate of the expected charges, given before the service. You are entitled to one on request, and automatically for anything scheduled at least three business days ahead.

For now, each estimate covers a single provider or facility. If several will be involved — the hospital, the surgeon, the anaesthesia group — ask each one for its own estimate.

The threshold

$400. If a provider or facility bills at least that much more than the total on its own estimate, you may use the patient-provider dispute resolution process. Below it, you can still ask, but the formal route is not available.

There is a deadline: generally 120 days from receiving the bill. Do not let it pass while you wait for a call back.

Try the billing office first

Asking costs nothing, and a correction from the billing office is faster than any formal process.

Please explain the [amount] difference from the Good Faith Estimate. I am considering the federal patient-provider dispute resolution process if it cannot be reconciled.

Say it calmly: it reads as informed rather than threatening.

When a higher bill is legitimate

An estimate is an estimate. Things genuinely change:

• Complications during the procedure
• A finding that required more work than planned
• A service you asked for on the day

What is not a good reason is a charge for something the provider knew about in advance and left off its own estimate.

If you use the formal process

You submit the estimate and the bill, generally within 120 days of receiving the bill, with a $25 non-refundable administrative fee. If the reviewer sides with you, the $25 comes off what you owe. The reviewer can hold the provider to its estimate or, where the provider shows the extra charges came from something it could not have foreseen, set an amount that can fall between the estimate and the bill.

While a dispute is open, the provider must not send the bill to collections or threaten to, and late fees on the disputed amount stop accruing. Say so in writing when you file.

Also worth doing

Ask about financial assistance at the same time, particularly at a nonprofit hospital. The two are not alternatives — a bill can be both wrong and reducible, and the financial assistance route often moves faster.

This is general information, not legal, medical or financial advice, and not a statement about your particular bill. A difference between two documents often has an ordinary explanation, and the billing office is the one who can give it.
