You can enroll anytime during an enrollment period - and you may wish to enroll as early as possible just to have the decision behind you - or if your health status is currently changing, you may wish enroll later in the enrollment period so that your Medicare plan choice can include coverage of your latest prescription and healthcare (and healthcare provider) needs.
We recommend: Not too early and not too late.
Your Medicare Part D or Medicare Advantage plan will need about 10 business days to process your new enrollment application - so we usually recommend that you enroll at least 2-weeks before the end of the enrollment period allowing a buffer for any administrative or technical errors that may require you to correct your application - or re-enroll into the same Medicare plan before the enrollment period expires. And, since none of us know the future, sometimes our health needs change unexpectedly and enrolling too early may mean that our chosen Medicare Part D or Medicare Advantage plan no longer provides the best coverage if our healthcare needs change before the end of the enrollment period.
- Enrollment timing during the Medicare Annual Open Enrollment Period (AEP)
The
Annual Open Enrollment Period (AEP) begins October 15th and continues through December 7th of every year and during the AEP, you can add, change, or drop Medicare Part D or Medicare Advantage plan coverage. As noted, if you find your health needs are constantly changing, then we usually suggest that you consider enrolling in or changing Medicare plans mid-November - in this way, you will have enough time to receive a confirmation of your enrollment or Medicare plan materials before the AEP closes.
Changing healthcare needs and changing data.
If your health is stable, you can enroll as early as October 15th and have plenty of time to study your Medicare plan material before your coverage begins on January 1st. However, we often hear from people who enroll on October 15th or early in the AEP, and then find their prescription needs change - or they find that the online Medicare plan information or a plan's retail drug pricing information has changed during the AEP - and their chosen Medicare plan is no longer the most economical alternative.
Waiting until the end of AEP.
If you wait to complete your enrollment or plan change until
early-December, your Medicare plan may not have enough time to confirm
your enrollment and send you a "Welcome" letter or initial plan
information before the December 7th closing of the AEP - and every year
we hear from people who learn of application processing errors after the
close of the AEP - and they are then forced to correct any errors to
ensure that they have any plan coverage on January 1st - or people get
busy and forget that December 7th is the end of AEP.
- Enrollment timing during your Initial Enrollment Period (IEP)
Your Medicare Part D
Initial Enrollment Period (IEP)
is a 7-month period that begins 3 months before the month when you
become eligible for Medicare (when you turn 65) - plus the month that
you are eligible for Medicare - and continues for 3 months after your
Medicare eligibility month. No matter when you enroll during the IEP,
Medicare plan coverage will not begin before the Medicare eligibility
month and if you enroll on or after your Medicare eligibility month,
your plan coverage will begin the first day of the month after
enrollment.
Too early?
Like the AEP above, if you enroll too early during your IEP, you may
find that you have changes in your health or prescription needs before
the start of your Medicare eligibility month. So if you wish to have
coverage starting the 1st day of your Medicare eligibility month, you
probably should enroll midway through the month before Medicare
eligibility so your Medicare plan will have plenty of time to send you
the plan material before coverage begins - or you can correct any
enrollment errors and still have coverage starting the 1st of the
month. (For example, if you turn 65 in June, choose your Medicare plan
coverage during early- or mid-May to ensure that your current healthcare
and prescription needs are met by the Medicare plan.)
Saving the premiums and starting Medicare plan coverage as late as possible?
If you are in good and stable health and do not need Medicare Part D
or Medicare Advantage plan coverage (and want to save a few months
premium), you could wait until mid-way through the last of the
seven-month Initial Enrollment Period - again, if there is an enrollment
problem, you should have enough time to correct the problem or
re-enroll before your IEP closes. (For example, if you turn 65 in June,
you have up to 3 months to enroll into a Medicare Part D or Medicare
Advantage plan after June, so if you do not need health or prescription
coverage and want to save on premiums, you can wait until mid-September
to enroll with plan coverage beginning October 1st.) But, if you wait
too long, you may find that you have missed your IEP and will need to
wait until an AEP to add Medicare plan coverage - and may incur the
permanent
late-enrollment penalty unless you have some other form of creditable prescription drug coverage.
- Enrollment timing during a Special Enrollment Period (SEP)
You may have the opportunity to change your Medicare Part D or Medicare
Advantage plan coverage outside the AEP if circumstances arise allowing
for a
Special Enrollment Period (SEP)
- for example, you move outside your Medicare plan's Service Area or
enter a Long-term Care Facility or you lose your employer's healthcare
coverage. The length of a Special Enrollment Period can vary with the
situation, with most SEPs being a relatively short amount of time (63
days). Like other enrollment periods, we recommend that you use your
SEP well before the ending date to be able to correct any enrollment
errors and have time to understand your coverage before your
newly-chosen Medicare plan begins.
