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 Allina Health | Aetna ID card or number

Your current Allina Health | Aetna ID card will remain the same. You should continue to use your Allina Health | 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 7 AM and 7 PM Monday through Friday.

Protect yourself from scams

Beware of anyone who contacts you about your new Medicare card. Medicare will never ask you to give us personal or private information to get your new Medicare number and card.

Where to find more information

You can find more information on the CMS site. Please take a minute to familiarize yourself with the upcoming new Medicare card changes.

Protect your medical records and identity

Because we’re committed to protecting the privacy of our members, we’re moving away from the use of Social Security numbers whenever possible. Thieves often steal Social Security numbers when they hack websites and computers. A Social Security number is not required for health care services.

Here's how you can help:

If you're a health care professional working with us:

  • Collect the patient's member ID number, rather than a Social Security number.
  • For your own transactions, use your Employer Identification Number (EIN), rather than a Social Security number.

If you're an Allina Health | Aetna member:

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

If you're an employer working with us:
