The Medicare Part D late-enrollment penalty (LEP) is an extra monthly fee that you pay
for prescription drug coverage
(PDP or MAPD
assessed when you were eligible for Medicare drug coverage, but did not join a drug plan and were without any creditable drug
coverage for more than 63 days
How is the Medicare Part D Late-Enrollment Penalty Calculated?
The LEP is calculated as 1% of the national base Medicare Part D premium for each month
you were without some form of creditable prescription drug coverage. For example, if you did not have drug coverage the first year you were eligible for Medicare, you would pay a penalty of 12% (for 12 months without drug coverage) of the national base premium ($33.37 in 2022) or $4 per month in addition to your Medicare drug plan premium.
How long does someone pay a Late-Enrollment Penalty?
penalty is permanent and you will pay
the penalty (adjusted each year for the annual base Medicare Part D
premium) as long as you have Medicare drug coverage.
Your Part D Late-Enrollment Penalty can change every year.
The Centers for Medicare and Medicaid Services (CMS) calculates and
releases the national base Medicare Part D premium each year and in
2022, the national base Medicare Part D premium is $33.37
slight increase over the
2021 base premium of $33.06
As reference, the following is a chart showing the annual national base Medicare Part D premium
values used to calculate late-enrollment penalties since 2006.

As noted, the Medicare Part D late-enrollment premium penalty (LEP) is an
additional monthly cost paid by Medicare Part D beneficiaries who did
not enroll in a Medicare Part D prescription drug plan when they were
first eligible and did not have any other form of "creditable" prescription drug coverage -
or who were without
prescription drug coverage for more than 63 days.
What is considered creditable drug coverage?
"Creditable drug coverage" is any prescription coverage that is at least as good as basic
Medicare Part D prescription drug coverage - and if you have some form of creditable drug coverage,
you do not need to join a Medicare Part D plan and will not be assessed a late-enrollment penalty
if you someday choose to add Part D prescription drug coverage. Some examples of creditable
drug coverage include VA (Veterans Administration) drug coverage, TRICARE, or employer/union drug
coverage (but check with your employer / union health plan administrator to verify your drug
coverage is "creditable" for purposes of Medicare Part D).
An example of how to estimate a 55-month 2022 Medicare Part D late-enrollment penalty
If you were previously without creditable prescription drug coverage from 2006 through 2010
(55 months without drug coverage) and then joined a Medicare Part D plan in 2011, you would pay
(in addition to your monthly
2022 Medicare plan premium) a monthly penalty of
(55 months without drug coverage * 1% of
$33.37 - rounded to the nearest $0.10) or around an additional
over the year for your drug coverage.
Below is a chart showing how your 55-month late-enrollment penalty would have changed
over the years (these are monthly costs that you will pay in addition to your Medicare Part D
or Medicare Advantage plan premium).
On a positive note:
You are not responsible for calculating your own
penalty. Your actual late-enrollment penalty will be calculated by the federal government,
reported to your Medicare Part D or Medicare Advantage plan, and then reported to you. If
you are wrongly assessed a late-enrollment penalty or believe that your penalty was incorrectly
calculated, you have the right to appeal your late-enrollment penalty
The cost of waiting: How large of a late-enrollment penalty could someone pay in
About $748.80 for the year.
is possible that you could have a late-enrollment penalty reaching as high as an additional
per month that must be paid in addition to your
2022 Medicare Part D or Medicare Advantage plan premium.
Here are the assumptions we used for our maximum LEP calculations.
Following these assumptions . . .
- You were eligible for Medicare back before January 2006 and
- You never joined a Medicare Part D plan until January 2022 and
- You are not eligible for the financial Extra Help program and
- You have been without any other creditable prescription drug coverage since the start of the Medicare Part D program (187 months) (we begin to count months starting with June 2006 through December 2021).
, we calculated the maximum penalty as 187 months
without drug coverage
multiplied by 1% of $33.37 = $62.402 rounded to the nearest $0.10, so $62.40. In other words,
if you were eligible for Medicare Part D coverage back in 2005 and first join a Medicare Part D plan
(or Medicare Advantage plan that includes drug coverage or MAPD) in January,
2022, you will pay an additional $748.80
2022 for your Medicare Part D drug coverage (and as you can imagine, this penalty can change
every year as the Medicare Part D base premium changes).
Below is a chart showing the ever-increasing "cost of waiting" to enroll in a Medicare Part D
plan when you do not have any other creditable drug coverage.
The decision to enroll - or not to enroll - when you are first eligible for Medicare
Part D plan coverage . . .
We use the "maximum penalty" chart (above) to emphasize the possible costs you may incur if
you do not have any other drug coverage and delay enrollment your Medicare Part D plan.
Aside from the penalty, if you decide to postpone Medicare Part D enrollment and then find
that you have prescription needs, you may need to wait
until the next annual Open Enrollment Period (starting October 15th and continuing through
December 7th) to join a plan with coverage starting the following January 1st - and you will
need to pay all of your prescription costs out-of-pocket until your Part D plan coverage starts.
Even if you currently use no prescription medications
and are in good health, look at the monthly costs on our above chart and consider enrolling
in a Medicare Part D plan or Medicare Advantage plan with the lowest monthly premium
(perhaps a Medicare Advantage plan that offers prescription drug coverage or MAPD with a $0 premium)
. And then consider your Medicare Part D plan as typical "insurance" that is available
should you need it.
Medicare Part D Base Premiums vs. Basic Premiums: How does the annual base Medicare Part D
premium compare to the CMS projected average basic Medicare Part D
The Basic Medicare Part D Premium.
Each year the Centers for Medicare and Medicaid Services (CMS) calculates a projected average
basic Medicare Part D premium, based on the proposed Medicare Part D (PDP) and Medicare Advantage plan (MAPD) plan premiums
submitted by plan providers (such as Aetna or Humana) - and weighted by current Medicare drug plan
enrollment. This basic premium is usually released in a CMS Press Release in late-July or
early-August every year.
In 2021, the projected
basic premium was $30.50
and the actual
2021 basic premium was $31.47.
The 2022 projected
average basic Part D premium is $33.01
up 4.9% from the 2021 from the actual basic premium.
The Base Medicare Part D Premium.
The Part D "base" premium (or national base monthly Medicare Part D premium) mentioned
throughout this article is used to calculate
penalty. The Medicare Part D base premium is also calculated by CMS each year
($33.37 in 2022) and released at the same time as the projected "basic premium".
The following chart shows how the CMS projected average "basic" Medicare Part D premium compares to the annual "base" Medicare Part D premium used to calculate the late-enrollment penalty.
You can read more about the 2022 projected
average basic Medicare Part D premium in our article here "CMS projects a 4.9% increase in 2022 Medicare prescription drug plan premiums"

Don't agree with your penalty? Appealing your late-enrollment penalty . . .
In certain situations, such as when you have only VA coverage or employer drug coverage or union drug coverage and no Medicare drug plan coverage, you can appeal your late-enrollment penalty
- but don't stop paying your penalty until your penalty appeal is successful.
No Part D late-enrollment penalties for low-income Medicare beneficiaries.
As noted above, no late-enrollment penalties are assessed on Medicare beneficiaries who qualify for the Medicare Part D financial Extra-Help or Low-Income Subsidy (LIS) program
(and if you are qualified for your state's Medicaid program, you are automatically qualified for Medicare Part D Extra Help). For additional assistance understanding your Medicare benefits, please call a Medicare representative at 1-800-633-4227 (1-800-Medicare).
