What is the Medicare Part D Late Enrollment Penalty?
You may incur a late 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 enrollment penalty is an additional amount added to your monthly Medicare
Part D premium. The specific cost of this fee depends on any period of lapse in
coverage. You will be required to pay the penalty for the length of your Medicare
prescription drug coverage.
