The 3 Most Important Things to Know:

The penalty for not signing up for Medicare Part D when you’re first eligible can add up, so it’s good to know how it works.

Here’s the scoop: if you don’t join a Medicare drug plan when you’re first eligible and go 63 days or more without other drug coverage that’s as good as Medicare (they call that “creditable coverage”), you might have to pay a late enrollment penalty.

This penalty is calculated by taking 1% of the “national base beneficiary premium” — which is around $33 in recent years — and multiplying it by the number of months you went without coverage. So, for each month you delayed, you’re looking at a 1% increase. That amount gets added to your monthly Part D premium for as long as you have Medicare prescription drug coverage.

The longer you go without coverage, the bigger the penalty. So, signing up when you’re first eligible is usually the best way to avoid it!

With a little bit of effort, you can find a plan that fits your needs and helps keep you healthy!
