No Surprises Act
The No Surprises Act is a U.S. federal law, effective January 2022, designed to protect patients from unexpected out-of-network medical bills during emergencies and when receiving care from out-of-network providers at in-network facilities.
Key protections
The law prevents out-of-network providers from billing patients more than in-network cost-sharing amounts for emergency services, regardless of whether the facility is in network. It also protects patients receiving non-emergency care at in-network facilities from surprise bills by out-of-network providers (such as anesthesiologists or pathologists).
Why it matters for fertility patients
Emergency pregnancy complications, such as ectopic pregnancy rupture or severe OHSS, often involve emergency surgery where the patient has no control over which providers are involved. The No Surprises Act limits patient financial exposure in these situations.
