The 21st Century Cures Act & the CMS Patient Access Final Rule

In December 2016, the 21st Century Cures Act was signed into law with several important goals, including increased patient access to their own health data. CMS created rules to further this goal. This is known as the CMS Interoperability and Patient Access final rule (CMS-9115- F). In order to increase patients' access to their health data, the rule requires health insurance plans to give members access and the ability to share their health plan data with third-party applications of their choice. 

What does this mean for you and your health plan?

WellFirst Health is committed to making sure that you have access to the information that you need to make decisions about your health. What this means is that we must make all of your claims and clinical data that we have in our systems available for you to access through the third-party applications of your choosing. 

WellFirst Health has contracted with 1upHealth, an industry leader in healthcare data integrations, and a cutting-edge data standard called FHIR, to give you access and the ability to share your data. If you choose to access your healthcare data through an application such as MyChart, Apple Health or FitBit, you will ask to connect these applications using the 1upHealth platform. To do this, you must confirm your identity for 1upHealth and WellFirst Health by entering the user ID and password that you use to log into your WellFirst Health member portal. After we verify your identity, we will share your healthcare data with the application you have chosen.  

Why share your data? Benefits & risks

There are many potential benefits to this new way to access and share your health information. Take a look at our app gallery for a sampling of the third-party applications that are being developed to help you better use this information. Some apps allow you to combine your data from multiple health providers to create a complete record of your interactions with different doctors and hospitals, and even combine it with data you generate on your own from wearable devices like glucose meters, pedometers or heart rate monitors. 

Some other common uses include: 

  • prescription drug management
  • chronic disease management
  • nutrition tracking
  • care coordination 


Data sharing empowers you to have greater ownership of and visibility into your health data.

However, these benefits are not without some risk. We take your privacy and the security of your health information as seriously as you do. That's why we never share your health information without your express permission. WellFirst Health protects your data throughout the process of sharing it in several ways, including using challenge questions and multi-factor authentication to confirm you – and no one else – can access and share your data. 

It is important to understand though, that once your data is shared with an application, WellFirst Health is no longer able to protect the security of that data. This is why it is important to read the privacy and security policies for any application you are considering sharing your data with, so you understand how it is protected and used by that application.

How to report identity theft and fraud

If you believe an application that you've shared your data with is misusing that information in violation of their stated privacy policy, or if you have a complaint, contact the Federal Trade Commission to investigate or call (877) 382-4357.

If you believe the privacy of your health care data has been violated, or if you have a complaint, contact the federal Department of Health and Human Services Office of Civil Rights.
