Part D

I decided not to sign up for a Part D drug plan when I first qualified for Medicare when I turned 65 last year, but now I want to enroll in a drug plan during the Medicare Open Enrollment period. Can I do that?

Yes, you can sign up for a Part D plan during the Medicare Open Enrollment period. However, you may also owe a late enrollment penalty because you didn’t sign up for Part D drug coverage when you first became eligible for Medicare. The penalty is equal to 1% of the national average premium amount for every month you didn’t have coverage as good as the standard Part D benefit.
