The No Surprises Act protects consumers who get coverage through their employer (including a federal, state, or local government), through the Health Insurance Marketplace® or directly through an individual health plan, beginning January 2022.

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

Dignity Health believes health care is a fundamental human right and should be accessible to all. That means making sure care is affordable. Dignity Health offers one of the most generous financial assistance policies in the nation, with free and discounted care to families that need it most. We also help uninsured patients apply for government or private insurance.

Dignity Health understands medical bills are complex and can be confusing. The information on this website will help guide you to better understand the care you receive and how much it costs. We are committed to transparency and helping our patients understand the services they receive and how they are billed.

Download a list of our standard charges for medical services here. In most cases, these charges do not reflect the price you would pay for these services, and are adjusted based on your insurance coverage and financial assistance you may be eligible for. The prices you see listed for service reflect an average cost, and yours may be different depending upon how they are delivered in a care circumstance.
