As you explore and learn how Medicare works – and more importantly, how it can work best for you – you’ll likely hear the phrase “Medicare Beneficiary Identifier,” better known as your MBI. In 2018, as a way to prevent medical identity theft, Medicare switched from using your social security number to an MBI, and knowing your MBI can help streamline the process for you before and after your appointments.
Here’s a few things you should know about MBIs:
So, what exactly is my MBI number, and who assigns it to me?
Your MBI is a randomly generated 11-character identifier that is unique to you, made up of a mix of numbers (0 through 9) and upper-case letters. Just like your social security number or your personal passwords, it’s important that you keep your MBI secure. Your MBI is used for all Medicare transactions, including claims, billing, and benefit inquiries.
It’s important to know your MBI
Because your MBI is used in all Medicare transactions, it is extremely important. If you do not have your MBI, your provider cannot bill Medicare, which may cause a delay in care. Knowing or having your MBI on hand can help streamline the claims and billing process, making it easier for you, your loved ones, and the care team working with you!
Where can you find your MBI?
You can find your MBI right on your Medicare card. You can also get your number by calling 1-800-MEDICARE (1-800-633-4227), or by logging in to your account on ssa.gov or medicare.gov. If you need a replacement Medicare card, you can request one through your online account.
When in doubt, bring your Medicare card with you!
While it’s important that you keep your MBI safe and secure, if you know you’re going to an appointment, consider putting it in your wallet and bringing it with you. When you’re checking in, talk with the front desk and ask to ensure they have your MBI so your provider can bill Medicare.
