What is the Medicare Part D Late Enrollment Penalty?
You may incur a late Part D enrollment penalty if there is a continuous period of 63 days or more at any
time after the end of your Initial Enrollment Period (IEP) during which you were eligible to enroll in a
Medicare Part D plan, but were not enrolled and not covered under any creditable prescription drug coverage.
A late Part D enrollment penalty is an additional amount added to your monthly Medicare Part D premium.
The specific cost of this fee depends on how long there was a lapse in coverage. You will be required to pay the
penalty for the duration of your Medicare prescription drug coverage.
Note: “Creditable coverage” is coverage as good as Medicare Part D coverage.
