Interoperability – Understanding what it means to you

MedStar Family Choice is committed to having our members have ease of access when it comes to managing digital health care data.

The Center for Medicare and Medicaid Services (CMS) enacted the Interoperability and Patient Access Rule (CMS Interoperability Rule) in 2020. This allows you to see your health data on a 3rd party health application (app). This process makes it easier for you to access your health records whenever and wherever you want.

Before you can utilize a third-party application, you must authorize MedStar Family Choice to share data with it. You will need to register yourself, and then provide valid login credentials each time you want to view your data.

Create a personal account by registering yourself

You will need to create an account by registering with MedStar Family Choice as the first step in allowing your App to access your data.

Member Registration
Members can register by entering their name, date of birth, email address, MedStar Family Choice ID number and the Medicaid ID number.

Personal Representative Registration
In order to register as a personal representative (e.g., power of attorney, legal guardian, parent of an adult member, parent, or guardian of a minor member), there are forms that need to be completed and submitted first.

You can find the forms at Once your Personal Rep application has been approved, you will receive an email with this registration link, and a Personal Representative Identifier (PRID). You will be able to register with MedStar Family Choice using the PRID, the Member ID and other distinguishing information. You will also be asked for second way to verify your identity.

Accessing your health data

Whenever you use your third-party app to view your MedStar Family Choice heath information, you will need to provide your credentials by logging in.

You will also need to provide consent to allow MedStar Family choice to share that data with the third-party app.

The apps that you have consented to will be listed in this Member portal.

If you decide you no longer want to use a particular third-party app, navigate to the specific app, and click on the REVOKE button. This will block that application from referencing your data.

Please visit our Interoperability page for more information and to see a list of apps that have registered with MedStar Family Choice.
