Estimate Your Health Care Costs

Dignity Health is committed to helping patients make informed decisions about their care. Our cost estimate tool helps you estimate your out-of-pocket costs for care. This tool provides cost estimates for at least 300 common medical services and procedures.

While this tool can help you estimate some health care costs, it’s important to know that it only provides a partial estimate. The estimate includes the hospital’s charges and fees, but it does not include physician fees, such as charges for your emergency room physician, radiologist or anesthesiologist. In addition, your final cost may be higher or lower depending on many factors, including insurance coverage, the length of your stay in the hospital, health complications and recommended treatments ordered by your doctor.

For a more complete understanding of your financial responsibility, contact your insurance provider. You may also contact us to speak with a Dignity Health financial counselor and learn about financial assistance options you may be eligible for.

Getting Started

To generate the most accurate estimate for your health care procedure, please have the following information available:

  • Insurance information, if applicable (not required)
  • Patient’s personal information, including contact information
  • The name of your procedure or service
