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

Under the law, health care providers need to give patients who don’t have insurance or who are not using insurance an estimate of the bill for medical items or services.

  • 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.

  • If you receive a bill that is at least $400 more than your Good Faith Estimate, you can dispute the bill. Make sure to save a copy or picture of the Good Faith Estimate.
