What should I do if I enrolled in a new Medicare Part D plan and still have not heard anything from my plan?

If you have recently enrolled in a Medicare plan and still have not received your new Medicare Part D or Medicare Advantage plan Member ID card, please contact your Medicare plan’s Member Services department - confirm your enrollment, and ask whether your new Member ID card was sent.

Remember that your Medicare plan will need about 10 business days (and you must allow for holidays and weekends) to process your enrollment application and send either a confirmation letter or your new member information packet (“Welcome Kit”).

Can't find your new Medicare plan's Contact Information?

If you cannot find the telephone number for your Medicare plan, we have most Medicare plan Member Services numbers available through our PDP-Finder.com/FL and MA-Finder.com/15202 tools. You can just look up your Medicare plan name, click on the plan name or the "Benefits and Contact Info" button to see the Member or Customer Services number for your plan.

Important: Still can't confirm your new Medicare plan enrollment?

If you still cannot find your plan's Member Services number - or you need additional assistance confirming your enrollment, you can also telephone Medicare at 1-800-633-4227, select the prescription drug option, and then choose the option to speak with a Medicare representative. Once connected, ask the representative to help you confirm your plan enrollment or find your Medicare plan’s contact information.

Important: No record of your enrollment and the enrollment deadline is approaching?

If the Medicare plan's Member Services department and/or a Medicare representative cannot verify that you have successfully enrolled into your chosen Medicare plan (Medicare Part D or Medicare Advantage plan) - and you are approaching your enrollment deadline (for example, it is December 1st and the annual Open Enrollment Period ends December 7th) - ask the Medicare representative or Member Services representative to "re-enroll" you into your chosen Medicare plan.  Please be sure to record the date of enrollment and enrollment confirmation code that you were provided during the enrollment process.

Important: Still no record of your enrollment after the close of your enrollment period?

If the enrollment period has closed (for example, it is now December 20th and you enrolled on December 1st before the December 7th end to the annual Open Enrollment Period) - and you still have not received any enrollment confirmation from your Medicare plan, you should contact a Medicare representative (1-800-633-4227) and confirm your enrollment. You may even have a confirmation number or a copy of the enrollment application that you submitted.

If the Medicare representative cannot find your plan enrollment, ask the representative whether you qualify for a Special Enrollment Period allowing you to join a Medicare plan outside of the annual Open Enrollment Period (that ended December 7th).

For example, the Special Enrollment Period might be based on the administrative error whereby your enrollment was not properly submitted.  You can click on the following link to learn more about Special Enrollment Periods on this site

Is your Medicare plan using the same Member ID card year-to-year?

Please note: In past years, we have heard from people who stayed with their same Medicare Part D or Medicare Advantage plan from the previous year and their Medicare plan has told them to use their same Member ID card for the following plan year.

For instance, if you stay with the same plan from 2025 to 2026 and you do not receive a new 2026 Member ID card, you may wish to ask your 2025 Medicare plan whether you should just use your card from the 2025 plan year. 

Tip: Don't throw away your 2025 plan information and card until January AND you have received your 2026 plan information and card.

However, if you changed Medicare plans, you cannot use your old Medicare plan card for your new Medicare plan coverage - for example, you cannot use a 2025 WellCare card to get coverage for your 2026 Humana Medicare plan.

And while waiting for your new Member ID card...

If you are waiting for your new or replacement card and need prescriptions, you can also ask the Member Services representative for several pieces of information that will identify your new Medicare Part D prescription drug plan:

(1) Your Member ID number,
(2) PCN (Pharmacy Control Number),
(3) Rx BIN, and
(4) Group ID (or Rx Group) number.

With these four numbers, you can get a prescription filled with Medicare Part D coverage while awaiting the arrival of your new Member ID card.

You may also find all of these four numbers printed on your Medicare Part D plan's “Welcome Letter” that you probably received within ten business days of enrolling in your Medicare plan.

Finally, as a last resort, you can also ask your pharmacist to contact your Medicare prescription drug plan to obtain your Member information. Your pharmacist will need your Medicare Beneficiary Identifier (MBI) (on your Red, White, and Blue Medicare card) and the name of your Medicare prescription drug plan.
