New Medicare Cards Are Coming

March 2018

Medicare beneficiaries may want to pay extra close attention to their mailboxes over the coming weeks and months.

In an effort to improve overall efficiency and to curtail fraud and abuse, the Centers for Medicare and Medicaid Services (CMS) are issuing new Medicare cards in 2018. Unlike the current Medicare cards, the new cards will not display the Social Security number of the beneficiary. In its place, there will be a randomly generated identification number that has no connection to any personal data of the beneficiary.

In previous years, a Medicare beneficiary’s Social Security number was also used as their Medicare identification number. This was intended to help health care providers identify patients and process billing transactions. As millions of people carried around their Medicare cards with their name and Social Security number printed on the front, however, they faced increased opportunities for identity theft and Medicare fraud.

The move to issue new, more secure Medicare cards comes in response to the Medicare Access and CHIP Reauthorization Act (MACRA) of 2015. MACRA aims to improve Medicare’s efficiency through a number of different measures, including the removal of Social Security numbers in an effort to combat fraud, minimize burden for both beneficiaries and providers and to minimize the disruption of Medicare operations.

When new Medicare cards will be sent

The CMS will be taking a full year to send out the new cards to the more than 58 million people enrolled in Medicare¹. Mailings will be staggered in waves according to geographic location and the schedule is as follows:

  • Wave 1: April - June 2018
    Delaware, District of Columbia, Maryland, Pennsylvania, Virginia, West Virginia

  • Wave 2: April - June 2018
    Alaska, American Samoa, California, Guam, Hawaii, Northern Mariana Islands, Oregon

  • Wave 3: After June 2018
    Arkansas, Illinois, Indiana, Iowa, Kansas, Minnesota, Nebraska, North Dakota, Oklahoma, South Dakota, Wisconsin

  • Wave 4: After June 2018
    Connecticut, Maine, Massachusetts, New Hampshire, New Jersey, New York, Rhode Island, Vermont

  • Wave 5: After June 2018
    Alabama, Florida, Georgia, North Carolina, South Carolina

  • Wave 6: After June 2018
    Arizona, Colorado, Idaho, Montana, Nevada, New Mexico, Texas, Utah, Washington, Wyoming

  • Wave 7: After June 2018
    Kentucky, Louisiana, Michigan, Mississippi, Missouri, Ohio, Puerto Rico, Tennessee, Virgin Islands

The statutory deadline for replacing all existing Medicare cards is April 16, 2019. It’s quite possible that people in some states may not receive their new Medicare cards until sometime in 2019.

New details regarding the mailing schedule are expected to emerge once the process gets underway. Beginning in April of 2018, beneficiaries can check the shipping status of their new Medicare card online at or by signing up to receive email updates (which you can also do on the federal Medicare website). Keep in mind that your friend’s or neighbor’s card may arrive before yours, as mailing schedules can vary within each state.

What your new Medicare card will look like

The new Medicare cards will be red, white and blue. They will look much like the current cards but will be paper and won’t be laminated like the current Medicare cards. The main difference is that the card holder’s Social Security number (which currently appears on the card, under the beneficiary’s name) will be replaced by the randomly-generated Medicare Beneficiary Identifier (MBI). The MBI which will be 11 characters long and will contain both numbers and uppercase letters. The MBI is “non-intelligent,” which means that the codes do not have any hidden or special meaning, and spouses will each be assigned their own MBI.

The beneficiary’s gender designation will also be removed, as will the beneficiary’s signature.

The MBI will be used for processes such as billing, service transactions, eligibility questions and claim status checks that previously required the beneficiary’s Social Security number. Health care providers are required to have systems and processes in place that will be equipped to accept the MBI for all patient interactions by April of 2018.

Beneficiaries who qualify for Medicare through the Railroad Retirement Board (RRB) will receive a card with the RRB logo in the upper left corner and the designation of “Railroad Retirement Board” at the bottom.

Medicare Advantage, Medicare Supplement Insurance (also called Medicare Supplement Insurance) and Medicare Part D prescription drug plans will continue using their own cards at their own discretion, but patients enrolled in these plans should still expect to receive a new Medicare card and should carry these new cards with them, along with any additional health care cards.

What to do when your new Medicare card arrives

When your new Medicare card arrives in the mail, you are encouraged to destroy your old card. Cards should be shredded, and not merely thrown in the trash. There is no need to activate the new card; it is ready to use as soon as you take it out of the mailbox.

Although your new Medicare card will be safer than the old one, it should still be safeguarded with the same level of care. Carry your card with you in a safe place and don’t share your MBI with anyone except your health care provider, pharmacist or insurer. Should you forget to bring your new card to an appointment, your health care provider may be able to look up your MBI in their system.

What to do until your new Medicare card arrives

The CMS will not reach out to beneficiaries to confirm whether or not they have received their new card. Anyone enrolled in Medicare should double-check to make sure that their current address is accurate and consistent with the one on file with the Social Security Administration. To check, you can create an online account with the Social Security Administration here or call 800-772-1213 (24 hours a day, 7 days a week) for assistance. TTY users may call 1-800-325-0778. You may use these same resources if your Medicare card (old or new) is ever lost, stolen or destroyed.

Do not engage with any unfamiliar individuals or organizations who contact you inquiring about information from your new Medicare card. CMS officials will not ask a beneficiary for personal or private information, and they will not ask for money during the process of issuing the new cards.

Some scammers may attempt to contact Medicare beneficiaries pretending to represent Medicare or the Social Security Administration in an effort to obtain information that can be used to compromise one’s identity. In fact, some cases of this happening have already been reported.

Beneficiaries may continue to use their old Medicare card until the new one arrives. There is no need to wait until the new card arrives in order to receive any medical care.

The dangers of Medicare fraud

Medicare fraud is big business. According to the Pulitzer Prize-winning Center for Public Integrity, improper Medicare payments tallied nearly $60 billion in 2016 alone. That number is more than twice as much as the National Institutes of Health spends annually on medical research and is equivalent to more than $1,000 per each Medicare beneficiary in the nation.

These enormous losses aren’t solely due to intentional fraud. Billing mistakes can also contribute to wasted Medicare funds, and Original Medicare’s payment error rate in 2016 was an alarming 11 percent. Billing errors may include simple overcharges and underpayments, as well as mistakes made with billing codes. Inefficiencies, such as overestimating the amount of diagnostic testing needed for a Medicare beneficiary, can also contribute to Medicare waste.

How Medicare fraud is carried out

Medicare fraud can be committed by doctors, insurance billers and patients. The acts can be carried out by a single person or by an entire organization or group. According to the CMS, Medicare fraud is defined as:

  • “Knowingly submitting, or causing to be submitted, false claims or making misrepresentations of fact to obtain a Federal health care payment for which no entitlement would otherwise exist.”

  • “Knowingly soliciting, receiving, offering, and/or paying remuneration to induce or reward referrals for items or services reimbursed by Federal health care programs.”

  • “Making prohibited referrals for certain designated health services.”

Some examples of Medicare fraud include:

  • Billing Medicare for appointments the patient did not attend.

  • Billing Medicare for services at a level of complexity that is higher than the services that were actually provided.

  • Billing for supplies and equipment that were not actually provided to the patient.

  • Receiving “kickbacks” from pharmaceutical or medical supply and equipment companies.

Medicare fraud also happens when someone takes the name and Social Security number of a Medicare beneficiary and uses that person’s identity to receive Medicare benefits on their behalf. The CMS hopes to reduce this type of fraud by removing Social Security numbers from the new Medicare cards.

Medicare “abuse” is classified differently than Medicare “fraud.” Medicare abuse is the practice of billing for unnecessary medical services, billing excessive charges for services or supplies or billing for multiple service or supply codes that should have been bundled together.

Medicare fraud and abuse lead to higher health care costs for everyone and can lead to increased taxes. A Medicare Fraud Strike Force was established in 2007 and has recouped around $3 billion that had been lost due to fraud and abuse.

How you can protect yourself from Medicare fraud

There are a few things you can do to help minimize your risk for being a victim of Medicare fraud.

  • Review your Medicare claims for errors.
    Save receipts and statements you receive from health care providers and compare this information with your processed claims. Make sure the information is consistent. You may view your claims by looking at your “Medicare Summary Notice” that will be mailed to you once a claim is processed, or by logging in to

  • Review the Medicare Fraud Handbook provided by the CMS.
    This detailed handbook outlines many of the ways you can keep yourself safe from fraud and how to identify Medicare fraud and abuse.

  • Protect your Medicare card and your Social Security card.
    Anyone who gets ahold of your Medicare card may be able to use your card to receive Medicare benefits on your behalf. If someone else uses your card, it may affect your annual Medicare coverage limits, and the bill for any non-covered services could arrive in your mailbox. This applies to both the old and new Medicare cards.
