How CMS websites use information they collect

CMS websites use a variety of Web measurement software tools. We use them to collect the information listed in the “Types of information collected” section above. The tools collect information automatically and continuously. No personally identifiable information is collected by these tools.

CMS website staff analyze and report on the collected data from these tools. The reports are available only to CMS website managers, members of the CMS websites communications and web teams, and other designated staff who need this information to perform their duties.

CMS websites may also use an online survey to collect opinions and feedback. This online survey appears on the bottom left of many pages on the site. You don't have to answer these questions. Please do not to include any personally identifiable information (PII) in comments you make. We analyze and use this information to improve the site's operation and content. The reports are available only to CMS website managers, members of the communications and Web teams, and other designated staff who require this information to perform their duties.

CMS websites keep the data from our measurement tools as long as needed to support the mission of the website.

How CMS websites use cookies

The Office of Management and Budget Memo M-10-22, Guidance for Online Use of Web Measurement and Customization Technologies, allows federal agencies to use session and persistent cookies.

When you visit any website, its server may generate a piece of text known as a "cookie" to place on your computer. The cookie allows the server to "remember" specific information about your visit while you are connected. The cookie makes it easier for you to use the dynamic features of Web pages. Cookies from CMS websites collect only information about your browser's visit to the site. They do not collect personal information about you.

There are two types of cookies: single session (temporary) and multi-session (persistent). Session cookies last only as long as your Web browser is open. Once you close your browser, the cookie disappears. Persistent cookies are stored on your computer for longer periods.

  • Session Cookies: We use session cookies for technical purposes such as to allow better navigation through our site. These cookies let our server know that you are continuing a visit to our site. The OMB Memo 10-22 Guidance defines our use of session cookies as "Usage Tier 1: Single Session.” The policy says, "This tier encompasses any use of single session web measurement and customization technologies."
  • Persistent Cookies: We use persistent cookies to understand the differences between new and returning CMS website visitors. Persistent cookies remain on your computer between visits to our site until they expire. The OMB Memo 10-22 Guidance defines our use of persistent cookies as "Usage Tier 2—Multi-session without Personally Identifiable Information (PII).†The policy says, "This tier encompasses any use of multi-session Web measurement and customization technologies when no PII is collected."

How we protect your personal information

You do not have to give us personal information to visit CMS websites. However, if you choose to receive alerts or e-newsletters, we collect your email address to complete the subscription process.

If you choose to provide us with personally identifiable information through an email message, request for information, paper or electronic form, questionnaire, survey, etc., we will maintain the information you provide only as long as needed to respond to your question or to fulfill the stated purpose of the communication.

If in order to contact you we store your personal information in a record system designed to retrieve information about you by personal identifier (name, personal email address, home mailing address, personal or mobile phone number, etc.), we will safeguard the information you provide in accordance with the Privacy Act of 1974, as amended (5 U.S.C. Section 552a).

If any CMS website operates a record system designed to retrieve information about you in order to accomplish its mission, a Privacy Act Notification Statement should be prominently and conspicuously displayed on the public-facing website or form which asks you to provide personally identifiable information. The notice must address the following five criteria:

  1. The CMS website's legal authorization to collect information about you
  2. Purpose of the information collection
  3. Routine uses for disclosure of information outside of CMS websites
  4. Whether the request made of you is voluntary or mandatory under law
  5. Effects of non-disclosure if you choose to not provide the requested information

Data safeguards and privacy

All uses of Web-based technologies comply with existing privacy and data safeguarding policies and standards. Information Technology (IT) systems owned and operated by CMS are assessed using Privacy Impact Assessments (PIAs) posted for public view on the Department of Health and Human Services (HHS) website ( CMS conducts and publishes a PIA for each use of a third-party website and application (TPWA) as they may have a different functionality or practice. TPWA PIAs are posted for public view on the HHS website at

Groups of records that contain information about an individual and are designed to be retrieved by the individual's name or other personal identifier linked to the individual are covered by the Privacy Act of 1974, as amended (5 U.S.C. Section 552a). For these records, CMS Systems of Record Notices are published in the Federal Register and posted on the CMS Senior Official for Privacy Website.

When you visit CMS websites, please look for the Privacy Notice posted on the main pages. When Web measurement and customization technologies are used, the Privacy Policy/Notice must provide:

  • Purpose of the web measurement and/or customization technology
  • Usage tier, session type, and technology used
  • Nature of the information collected
  • Purpose and use of the information
  • Whether and to whom the information will be disclosed
  • Privacy safeguards applied to the information
  • Data retention policy for the information
  • Whether the technology is enabled by default or not and why
  • How to opt out of the web measurement/customization technology
  • Statement that opting out still permits users to access comparable information or services
  • Identities of all third-party vendors involved in the measurement and customization process

How long we keep data and how we access it

CMS websites keep data collected long enough to achieve the specified objective for which they were collected. The data generated from these activities falls under the National Archives and Records Administration (NARA) General Records Schedule (GRS) 20-item IC “Electronic Records,” and will be handled according to the requirements of that schedule (

How CMS websites use third-party websites and applications

As a response to OMB Memo M-10-06, Open Government Directive, CMS websites use a variety of technologies and social media services to communicate and interact with citizens. These third-party website and application (TPWA) tools include popular social networking and media sites, open source software communities, and more. Examples include Facebook, Twitter, and YouTube.

TPWAs are not exclusively operated or controlled by CMS websites. Users of TPWAs often share information with the general public, user community, and/or the third party operating the website. These actors may use this information in a variety of ways. TPWAs could cause PII to become available or accessible to CMS websites and the public, regardless of whether the information is explicitly asked for or collected by us.

CMS websites sometime collect and use your PII if you made it available through third-party websites. However, we do not share PII made available through third-party websites. Your activity on the third-party websites we use is governed by the security and privacy policies of those sites. You should review the third-party privacy policies before using the sites and ensure that you understand how your information may be used.

If you have an account with a third-party website and choose to “like,” “friend,” follow, or comment, certain PII associated with your account may be made available to CMS websites based on the privacy policy of the third-party website and your privacy settings within that website. You should adjust privacy settings on your account to match your preferences.

We also collect non-personally identifiable information through the use of tracking pixels that appear on our pages. A tracking pixel is a transparent graphic image (usually 1 pixel x 1 pixel) that is placed on a web page and, in combination with a cookie, allows us to collect information regarding the use of the web page that contains the tracking pixel.

We use tracking pixels to tell when an advertisement we run on another website has been clicked on or otherwise interacted with. We use that information to judge which advertisements are more appealing to users. To opt out of these tracking pixels, please see the section above titled “How to opt out or disable cookies.”

Links to other sites

CMS websites link to other HHS sites, other government sites, and occasionally to private organizations. Once you leave a CMS website, you are subject to the privacy policy for the sites you are visiting.
