Did You Miss Medicare Drug Coverage?
Did you know skipping Part D can cost you money every month — forever?
If you went more than 63 days without Medicare drug coverage or other creditable drug insurance after becoming eligible for Medicare, you may be paying — or about to pay — a permanent surcharge on your Part D premium. It doesn't matter whether you take prescriptions. The penalty clock doesn't care.
Here's how the penalty works
Medicare adds 1% of the national base beneficiary premium for every full month you went without creditable drug coverage. In 2025, that base premium is $36.78/month — so each 12-month gap adds roughly $4.40/month to your Part D cost, permanently.
That amount recalculates every year when the base premium changes — but your penalty percentage is locked in forever based on how long you delayed. A five-year gap means you pay 60% more than the standard rate for as long as you're on Medicare.
The good news: in some cases the penalty can be disputed. If you had coverage during the gap that qualified as creditable but wasn't reported, there's an appeal process. And for anyone who hasn't enrolled yet — there are still ways to minimize or avoid the penalty altogether.
Does your past coverage count?
These generally protect you from the penalty:
Your insurer was required to send you an annual "creditable coverage" notice. If you have that letter, it's your best evidence for an appeal.
Common scenarios
Here's how the penalty rules apply to situations we hear about most often in Bend and Central Oregon.
"I was on COBRA after leaving my job. Does that count?"
"I'm a veteran with VA coverage. Am I penalized if I enroll in Part D late?"
"My employer had drug coverage but I'm not sure if it was creditable."
"I didn't know I needed to enroll. Can I get the penalty waived?"
