Providers and facilities must give you the good faith estimate:

• After you schedule a health care item or service. If you schedule an item or service at least 3 business days before the date you’ll get the item or service, the provider must give you a good faith estimate no later than 1 business day after scheduling. If you schedule the item or service OR ask for cost information about it at least 10 business days before the date you get the item or service, the provider or facility must give you a good faith estimate no later than 3 business days after you schedule or ask for the estimate.
• That includes a list of each item or service (with the provider or facility), and specific details, like the health care service code.
• In a way that’s accessible to you, like in large print, Braille, audio files, or other forms of communication. Providers and facilities must also explain the good faith estimate to you over the phone or in person if you ask, then follow up with a written (paper or electronic) estimate, per your preferred form of communication.

Keep the estimate in a safe place so you can compare it to any bills you get later. After you get a bill for the items or services, if the billed amount is $400 or more above the good faith estimate, you may be eligible to dispute the bill.
