Medicare Late Enrollment Penalties

Part B Late Enrollment Penalty

If you don't sign up for Part B when you're first eligible or if you drop Part B and then get it later, you may have to pay a late enrollment penalty for as long as you have Medicare. Your monthly premium for Part B may go up 10% for each full 12-month period that you could have had Part B, but didn't sign up for it.

Part D Late Enrollment Penalty

This may apply if you don’t have creditable drug coverage when:

Your Initial Enrollment Period is over.

There’s a period of 60 days or more in a row when you don’t have Part D or other creditable prescription drug coverage.

Note: If you get Extra Help, you don’t pay a Part D late enrollment penalty.
