Your rights

No Surprises Act (implemented via CMS)

Surprise billing protections
Patients are protected from unexpected out-of-network bills for: "Emergency room visits"; "Non-emergency care related to a visit to an in-network hospital, hospital outpatient department, or ambulatory surgical center"; and "Air ambulance services."
Good faith estimate
Uninsured/self-pay patients: "providers must give you a good faith estimate of how much your health care will cost if you request one or schedule services at least 3 business days in advance."
Dispute process
"You may be able to dispute your bill if it's at least $400 more than the estimate."
