The No Surprises Act (NSA) gives consumers new federal protections from surprise medical bills by prohibiting balance billing and limiting consumer cost sharing in certain circumstances where surprise billing has been common.
The Centers for Medicare & Medicaid Service has released a No Surprises Act toolkit to help assisters and advocates who work with consumers faced with surprise medical bills. The toolkit contains more than 20 individual resources and a PDF compilation of all the resources.
