You Have The Right To Receive A “Good Faith Estimate” Explaining How Much Your Medical Care Will Cost.

  • You have the right to receive a Good Faith Estimate for the total expected cost of any non-emergency items or services. This includes related costs like medical tests, prescription drugs, and equipment.

  • Make sure your health care provider gives you a Good Faith Estimate in writing at least 1 business day before your medical service or item. You can also ask your health care provider, and any other provider you choose, for a Good Faith Estimate before you schedule an item or service.
