Frequently Asked Questions

I already have a doctor. How can I benefit from Castlight?

You can use Castlight when a doctor recommends lab work, specialists. prescriptions, and other medical services to learn about other providers and the associated costs and quality. Many doctors suggest specialists, labs, and other medical facilities without having any idea how much they charge or if they are in-network. However, doctors can provide multiple provider options that members can research in Castlight.

You can also use Castlight to search for services for your family members and to review your past healthcare spending.

How do I use Castlight when I’m not at a computer?

You can download the Castlight mobile app or call Castlight to speak with a “Castlight Guide” toll-free at 888-722-0483, Monday through Friday, 9 a.m.–9 p.m. ET.

How often is the information in Castlight updated?

Castlight updates plan and deductible status every time you visit a provider or purchase a medication, and updates past medical history and pricing data monthly.

Why are some of my past years of claims data missing?

Claims history is only available for the months/years you were enrolled in an IU-sponsored medical plan. If you and your spouse are both IU employees and have switched coverage from one spouse to the other over the years, the history will appear until the policy holders account only.

Claims data prior to January 1, 2017, for IU Health HDHP participants is not available in Castlight.

I found my provider in Castlight, but the information is inaccurate.

Castlight uses data received from Anthem and IU Health to create the provider listing. Sometimes providers have not updated a new office address and phone number or notified medical plan vendors that they are accepting new patients. Once that information is updated with each vendor, it will then be updated in Castlight, as well.

Where does Castlight get its quality information?

Information on quality comes from a wide range of public and private sources, including The Leapfrog Group for Patient Safety, the U.S. Department of Health and Human Services, other governmental reporting agencies, and consumer rating resources.

Where does Castlight get its cost information?

The cost information in Castlight is based on past claims paid for IU-sponsored medical plan members. This information is updated continuously as ongoing medical claims are submitted to the Anthem and IU Health plans. Although all medical services may not show prices in Castlight, the most common doctors and services utilized by IU medical plan members will show up in the tool and the amount of useful information increases frequently.
