Why You Shouldn’t Delay Signing Up for Medicare—The Penalties Are Real

Medicare offers essential healthcare coverage, but the penalties for missing enrollment deadlines are significant and long-lasting. If you don’t sign up for Medicare on time, you could face lifetime penalties, and these aren’t just one-time fees—they increase your premiums for as long as you have Medicare. Here’s what you need to know about avoiding these penalties and the real cost of delaying enrollment.

Understanding the Initial Enrollment Period (IEP)

Your Initial Enrollment Period (IEP) is the most critical time to sign up for Medicare. It begins three months before the month you turn 65 and ends three months after your birthday month. Missing this seven-month window could result in significant penalties, particularly for Part B and Part D.

If you don’t enroll in Medicare Part B during your IEP, you’ll face a penalty of 10% for every 12-month period you could have had coverage but didn’t. For example, the Part B premium in 2024 is $174.70. If you delayed enrolling for two years, you would face a 20% penalty, raising your monthly premium to $209.60 for the rest of your life.

The Part D prescription drug penalty works similarly. For each month you go without Part D or other creditable drug coverage, you will pay a penalty of 1% of the national base beneficiary premium, which is $34.70 in 2024. For example, if you delay enrolling for 14 months, your penalty would be $4.90 per month, added to your Part D premium.

What is the General Enrollment Period (GEP)?

If you miss your IEP, the General Enrollment Period (GEP) is another chance to sign up. The GEP runs from January 1 to March 31 each year, with coverage starting on the first day of the month after you enroll. However, you’ll still face penalties if you delayed enrollment, and these penalties are permanent.

For example, if you sign up for Part B two years late during the GEP, you’ll face a 20% penalty. Your monthly premium will jump to $209.60. This increase is lifelong and will adjust each year with changes to the base premium.

Special Enrollment Periods (SEPs) for Delayed Enrollment

There are specific circumstances where you can delay Medicare enrollment without facing a penalty, such as if you or your spouse are still working and covered under a group health plan. In this case, you qualify for a Special Enrollment Period (SEP) once the employment or coverage ends. You have an eight-month window after losing your employer coverage to enroll in Medicare without penalties.

However, it’s crucial to note that COBRA or marketplace plans are not considered creditable coverage for Medicare purposes. If you rely on these after you’re first eligible for Medicare, you could face penalties when you eventually enroll.

Understanding Part D and Creditable Coverage

Medicare Part D is the prescription drug plan, and the penalties for late enrollment can be costly. If you go without creditable drug coverage for 63 days or more, you’ll pay a penalty when you eventually sign up for Part D. The penalty is calculated as 1% of the national base beneficiary premium ($34.70 in 2024) for each month you go without coverage. This amount is added to your monthly premium for as long as you have Part D.

For example, delaying Part D enrollment by just one year (12 months) would result in a penalty of $4.16 per month. While this might not sound like much, it adds up over time, and the penalty increases as the national base premium rises each year.

How to Avoid Medicare Penalties

Avoiding Medicare penalties is simple if you understand the rules and enrollment periods. Here are key steps to ensure you don’t miss your deadlines:

1. Enroll during your Initial Enrollment Period (IEP): This seven-month window around your 65th birthday is your primary opportunity to sign up for Medicare without penalties.
2. Review your coverage if you’re still working: If you have employer-provided health insurance after turning 65, ensure that it qualifies as creditable coverage. If it does, you can delay Medicare without penalties, but be sure to enroll as soon as you lose this coverage.
3. Don’t rely on COBRA or marketplace plans: These options do not count as creditable coverage for Medicare, and enrolling in them instead of Medicare can lead to late enrollment penalties.
4. Pay attention to Open Enrollment: From October 15 to December 7, you can adjust your Part D or Medicare Advantage coverage. If you missed your initial sign-up, you may still be able to join during the General Enrollment Period.

Financial Impact of Delaying Medicare Enrollment

Medicare penalties can quickly become a financial burden. If you delay enrolling in Part B for two years, your monthly premium will increase from $174.70 to $209.60, which is a 20% increase. Over the course of a year, that’s nearly $420 extra you’ll be paying—forever.

Similarly, the Part D penalty grows each month you delay. A 12-month delay will add $4.16 to your monthly premium. This doesn’t sound like much, but after several years, the financial impact becomes substantial, especially as base premiums rise annually.

Take Action Now: Avoid the Penalties

To avoid these lifelong penalties, it’s crucial to sign up for Medicare as soon as you’re eligible, or ensure that you have creditable coverage through your employer. Missing the deadlines could cost you hundreds or even thousands of dollars over the course of your lifetime. Take control of your healthcare costs by understanding the rules and enrolling on time.
