What does the letter after my Medicare number mean?

March 2018 Update - Medicare Cards are Changing - New Card, Same Benefits
The Centers for Medicare and Medicaid Services (CMS) is mailing new Medicare cards starting April 2018 and continuing through April 2019. As noted by CMS, "[t]he new cards will use a unique, randomly-assigned 11-digit number called a Medicare Beneficiary Identifier (MBI), to replace the Social Security-based Health Insurance Claim Number (HICN) currently used on the Medicare card." CMS also noted that this initiative "will prevent fraud, fight identity theft and protect essential program funding and the private healthcare and financial information of our Medicare beneficiaries." To learn more about the new Medicare cards, please click on the following link for our FAQ: "What do we need to know about the new Medicare cards?" https://Q1FAQ.com/707.html

"What does the letter after my Medicare number mean?"

We have been getting more questions from people asking what the letters mean in their Medicare Claim Number.  Here is an explanation and chart of the letter meaning provided by the Social Security Administration:

The Social Security number followed by one of these codes is often referred to as a claim number.  Social Security assigns these codes once you apply for benefits.  These letter codes may appear on correspondence you receive from Social Security or on your Medicare card.  They will never appear on a Social Security card.

For example, if the wage earner applying for benefits and your number is 123-45-6789, then your claim number is 123-45-6789A. This number will also be used as your Medicare claim number, once you are eligible for Medicare.
