The "No Surprises Act Enforcement Act" is designed to enhance the enforcement of balance billing requirements for group health plans and health insurance issuers. Balance billing refers to the practice where patients receive unexpected bills from out-of-network providers for services they believed would be covered by their insurance. This legislation aims to protect patients from these surprise medical costs by increasing penalties for violations of balance billing rules. Key provisions include raising fines for non-compliance from 00 per day to 0,000 for each violation.
