What is a surprise medical bill?

A surprise medical bill is a charge you never knowingly agreed to: you went to an in-network hospital, but someone in your care - the anesthesiologist, the radiologist, the assistant surgeon, the lab - was out-of-network, and weeks later a separate bill arrives for the difference between their charges and your insurance rate. Or the ER itself: the nearest emergency room turns out to be out-of-network, as if anyone shops during an emergency. The good news is a federal law now bans the worst of it: the No Surprises Act, in effect since January 1, 2022, protects insured patients from unexpected out-of-network bills for emergency room visits and for non-emergency care from out-of-network providers at in-network facilities - in those situations you pay only your normal in-network cost-sharing, and the insurer and provider fight out the rest between themselves. The law also gives uninsured patients a right to a good faith estimate of costs before scheduled care. What it does not cover: ground ambulances, and bills for care you chose out-of-network knowingly. If a bill that smells like these protections arrives anyway, do not pay it first - CMS runs a help desk and dispute process at cms.gov/medical-bill-rights.
