Unique Features of Castlight

How does Castlight compare to other services on the Internet?

Castlight is a unique service customized for IU employees. It gives personalized pricing information, shows how much out-of-pocket costs will be for medical services and medications based on your health plan, and lists in-network doctors under the health plan. Castlight also provides an overview of health plan benefits, tips for making smart health care decisions, and details about past claims.

How is Castlight different from other websites?

Castlight makes it easy to compare doctors side by side based on price, quality and location. It shows actual out-of-pocket costs based on the member's annual deductible status for a wide range of medical services, and shows the member's remaining annual deductible right on the Castlight home page at each login.

Using Castlight

What can I do with Castlight?

Common uses include:

  • Searching for a primary care physician for any family member and find provider profile information, the provider’s gender, where they went to medical school, how long they have been practicing, and if they are accepting new patients.
  • Reviewing prior medical claims by reviewing past spending for healthcare, and see annual deductible balances.
  • Estimating personalized costs for medical services based on the medical plan and amount of deductible that has been met.
  • Compare in-network doctors, facilities, and medical services based on prices and patient reviews.
  • Receiving helpful tips about ways to reduce medical bills while locating high-quality care.

If I already have a doctor, how can I benefit from the tool?

Use Castlight when a doctor recommends lab work, specialists 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.

Employees can also use Castlight to search for services for other family members. In addition, it provides an easy and helpful way to understand past health care spending.

What types of care can I search for on Castlight?

Castlight supports a wide range of searches, including doctors, specialists, services and medical conditions. To see the list of supported searches, log in to Castlight.

How can I use Castlight when I'm not at a computer?

Access information through the Castlight mobile app or call Castlight to speak with a “Castlight Guide” toll-free at 888-272-9572, Monday through Friday, 8 a.m. – 9 p.m. ET.

What features are available on the Castlight mobile application?

Find providers, compare doctors, view health plan details, and see bookmarked doctors using the mobile app.

What are Castlight Guides, and how can they help?

Castlight Guides are dedicated customer service experts who are able to provide full access to the Transparency tool services over the telephone at 888-272-9572. Castlight Guides can be reached when at a doctor’s office or when considering treatment options while away from a computer.

How often will I hear from Castlight?

Castlight will email personalized savings tips and notifications when past care history has been updated. In addition, Castlight sends standard account maintenance notices, such as password change confirmations. Members can always change email settings on the "Your Account" page in the tool.

For users registered for claims-based notifications, Castlight only sends a maximum of one alert per week. Even if there are multiple claims updated in one week, Castlight will only send one alert to notify users of new claims. This reminds users to review claims without receiving frequent or multiple emails.

Where do I go for more help with Castlight?

The fastest way to get help with Castlight is to call toll-free at 888-272-9572. A Castlight Guide will be able to answer questions or direct your call.

Why am I not seeing all of my claims from 2010 on the Past Care tab?

Only medical claims for part of the 2010 plan year will show in Castlight, so IU plan members will not see all of their medical claims history for 2010. However, those enrolled in an IU-sponsored Anthem PPO plan should see their medical claim history for each year after that. Please note that only prescription claims that were paid through Express Scripts since January 1, 2012 will show on the Past Care tab.

Why do I see some years of claims history on the Past Care tab, but some years are missing?

Employees that enrolled continuously in an IU-sponsored medical plan from year to year should see each year of their claims history on the Past Care tab. However, if enrollment was not continuous, employees will only see the years when they were enrolled.  Additionally, if both spouses are IU employees and have switched coverage from one spouse to the other over the years, not all history will show on the Past Care tab. Only history for the years for the current spouse holding the policy will appear in the tool.

Why am I missing recent claims from the Past Care tab?

Castlight contains claims history, but there is a lag of about 30-60 days for recent claims to appear in the tool. So, recent claims will be added over time, usually about one to two months after the claim is incurred.

Why does the dollar amount spent on the Home tab not match the spending overview on the Past Care tab?

The spent to date amount on the Home tab shows the employee where they are at in their deductible today (including both medical and prescription claims for those on an HDHP).  Castlight updates plan and deductible status on the Home tab each time you login to capture recent visits to providers and medication purchases. 

The claim history on the Past Care tab is updated monthly, so the spending overview will update once per month when claim history is updated. 

I am enrolled in the IU Health Plan. Why am I not able to create an account or login to Castlight?

At this point in time, only employees on an IU-sponsored Anthem PPO plan are able to register for Castlight. An announcement will be sent out when the tool is available for IU Health Plan members.

I found my provider in Castlight, but the information is not accurate. Why?

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

If I have multiple medical services, or prescriptions from the same provider in the same day, why does Castlight show one dollar amount for all services on the Past Care tab?

Employees who receive multiple medical services or prescriptions on the same day billed by the same provider can view a roll-up of their claims for all services on the Past Care tab. To view a breakout of each medical service or prescription for that date, click on the service and expand the Summary section for that claim.

Provider Ratings

Where does Castlight get information about the quality of medical facilities, like hospitals?

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.

Can I add a review about an experience I had with a specific provider?

Castlight is committed to providing high-quality user reviews to help guide healthcare choices, including integrating reviews from third party sources like Angie’s List, Yahoo! Local and Insider Pages. Additionally, IU members can submit personal provider reviews directly through the Castlight website.

Troubleshooting Issues

What internet browsers does Castlight support?

Castlight users should operate Castlight on the current versions of Chrome, Firefox, or Internet Explorer in order to have an optimal experience. Castlight will no longer support IE7 or IE8 in compatibility mode.

The search results are not within the requested range of my home address. What's wrong?

Castlight uses the Google Map feature to determine providers within a search radius. Certain address abbreviations do not work well with Google Maps. These include directional abbreviations, such as E for East and the abbreviation St. Rd. for State Road. As a default, Castlight pulls a member’s home address from IU’s system, which may include these abbreviations.

To see accurate provider results, you can change your default address in Castlight. Your default address appears under the “Looking for something else?” search box on the Castlight home page. Click the “(Change)” link next to your address to re-enter it in a format that works with Google Maps. Change addresses such as 300 N 500 S to 300 North 500 South. Change an address such as 3399 St. Rd. 25 N to 3399 State Road 25 North. Your new default address will remain in effect until you change it. Castlight will also accept just the city and state as a default search address, if you prefer.

Personal Information in Castlight

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.

Is information private and secure?

Activities on Castlight remain private and are not shared with Indiana University. Castlight is also a member of TRUSTe, the leading authority for ensuring proper privacy standards on the Web. For more information on Castlight's strict privacy standards, please see the Castlight privacy policy.

Castlight maintains the highest security standards and is obligated under federal HIPAA guidelines to keep your data safe. Castlight has partnered with McAfee and VeriSign to ensure adherence to some of the strictest security standards in the industry.
