Balance-bill check
A balance bill is the gap between the hospital charge and what the plan allowed. Some of those gaps are limited by federal surprise-billing rules.
A balance bill is the amount left after the plan’s allowed payment. The No Surprises Act limits some of those bills. It does not limit all of them, and this page does not calculate what you owe.
Emergency services from an out-of-network provider are generally protected. Your cost share should be based on the in-network amount, and the provider generally should not balance-bill you beyond that. Confirm it on the explanation of benefits. Air ambulance from an out-of-network provider is also covered by those federal rules.
Non-emergency care from an out-of-network clinician at an in-network facility is often protected. Some services can fall outside that protection if you received a proper notice and consented. Read anything you signed. Compare the clinician’s bill with the explanation of benefits before you pay.
If you scheduled non-emergency care at an out-of-network hospital, surprise-billing protections often do not apply. You may owe the gap. Ask the plan for the allowed amount and ask the hospital for a discount in writing. The figure review still checks the hospital’s own arithmetic.
Federal surprise-billing rules generally do not cap ground ambulance balance bills. Air ambulance is different. Ask the plan what it allowed, and ask the ambulance company for an itemized bill and any hardship discount.
In network, the number to pay is the patient responsibility on the explanation of benefits: deductible, copay, and coinsurance. If the hospital’s bill is higher than that column, do not pay the difference until the plan and the hospital explain it.
