Turning 65 is a major milestone, but it also brings a not-so-fun homework assignment: figuring out Medicare.
While the system can feel like an alphabet soup, the most important thing you need to know right now is this: missing your enrollment deadlines can result in permanent financial penalties.
If you are retiring and don’t have health coverage through a current employer, here is a simple breakdown of the Medicare parts you must apply for to avoid lifetime late fees.
First, Know Your Window
You have a 7-month Initial Enrollment Period (IEP). It includes the three months before your 65th birthday, your birthday month, and the three months after. This is your golden window to act.
1. Medicare Part B (Medical Insurance)
Do I need it? Yes. Unless you or your spouse are still working and get health insurance from that employer (and the company has 20+ employees), you must sign up for Part B.
The Penalty: If you delay without having employer coverage, your Part B monthly premium will go up by 10% for every full year you waited. You will pay this penalty for the rest of your life.
2. Medicare Part D (Prescription Drugs)
Do I need it? Yes. Even if you don’t take any medications right now, Medicare requires you to have prescription drug coverage. You must choose a Part D plan unless you have “creditable” drug coverage from elsewhere (like an employer or the VA).
The Penalty: If you go 63 days or more without drug coverage, you’ll face a permanent penalty of 1% of the national base premium for every month you delayed. Like Part B, this penalty sticks with you for life.
3. Medicare Part A (Hospital Insurance)
Do I need it? It depends on your work history.
- If it’s free: If you or your spouse worked and paid Medicare taxes for at least 10 years, Part A is completely free. Because it’s free, there is no penalty for signing up late.
- If you have to buy it: If you don’t have the 10-year work history and have to pay a monthly premium for Part A, you must sign up during your 7-month window. Delaying means a 10% premium penalty that lasts for twice the number of years you waited.
What about Part C (Medicare Advantage)?
You might see a lot of commercials for Medicare Part C. These are private all-in-one plans that bundle Parts A, B, and D together. Part C is completely optional. You will never be penalized for choosing not to buy a Medicare Advantage plan.
The Bottom Line
If you are turning 65 and retiring, sign up for Part A, Part B, and Part D during your 7-month window.
Still working? Talk to your HR department right away. Ask them to provide written proof that your current employer plan is considered “creditable” by Medicare. As long as it is, you can safely delay Parts B and D without fear of penalties until you retire!
