The Part D penalty applies if you went 63 days or more without Medicare Part D or other creditable prescription drug coverage after becoming eligible for Medicare. The penalty is 1% of the national base beneficiary premium for every full month you went without coverage — and it's added to your Part D premium for as long as you have Part D.
