Part D Costs
Most people only pay their Part D premium. If you don’t sign up for Part D when you’re first eligible, you may have to pay a Part D late enrollment penalty.
If you have a higher income, you might pay more for your Medicare drug coverage. If your income is above a certain limit ($91,000 if you file individually or $182,000 if you’re married and file jointly), you’ll pay an extra amount in addition to your plan premium (sometimes called “Part D-IRMAA”). You’ll also have to pay this extra amount if you’re in a Medicare Advantage Plan that includes drug coverage. This doesn’t affect everyone, so most people won’t have to pay an extra amount. If you have Part B and you have a higher income, you may also have to pay an extra amount for your Part B premium, even if you don’t have drug coverage. The chart below lists the extra amount costs by income.
