Our effort to reduce the use of SSNs

CMS to eliminate use of SSNs on Medicare cards

Personal identity theft affects a large and growing number of seniors. People age 65 or older are increasingly the victims of this type of crime. So, the Centers for Medicare & Medicaid Services (CMS) is starting a fraud prevention initiative that removes Social Security Numbers from Medicare cards. This will help fight identity theft and safeguard taxpayer dollars.

You’ll get a new Medicare card and number

Between April 2018 and April 2019, CMS is removing Social Security numbers from Medicare cards and mailing each person a new red, white and blue Medicare card.  This will include your new, unique Medicare number. Your new card and Medicare number won’t change your coverage or your Medicare benefits.  Once you get the new card, you should destroy your old card and start using the new card right away. 


This doesn’t impact your Aetna ID card or number


Your current Aetna ID card will remain the same.  You should continue to use your Aetna ID when you go to the doctor.  This change is specific to your CMS issued red, white and blue Medicare card only.


How to get ready


You don’t need to do anything to get a new card.  But, you should make sure your mailing address is up to date with CMS.  You can update your mailing address by visiting or calling 1-800-772-1213  (TTY: 1-800-325-0778).  This number is an automated telephone service, available 24 hours a day.  If you cannot handle your business through the automated services, you can speak to a Social Security representative between 8 AM and 7 PM Monday through Friday.


Protect yourself from scams


Medicare will never call uninvited and ask for your personal or private information to get a new Medicare Number and card. Scam artists may try to get personal information (like your current Medicare Number) by contacting you about your new card. If you are asked for information, for money, or someone threatens to cancel your health benefits if you don't share personal information, call 1-800-MEDICARE (1-800-633-4227).

We'll continue to accept the HICN through the transition period

Here's how you can help

If you're an Aetna member:


Give your member ID number -- not your Social Security number -- when you go to the doctor, dentist or hospital.
