Switching From Marketplace to Medicare: Your Easy Guide

Hey there! So you're turning 65, or maybe you've become eligible for Medicare earlier due to a disability. If you're currently enrolled in a Marketplace plan through the Affordable Care Act (often called "Obamacare"), this is kind of a big deal. It's like you're moving from one neighborhood to another different rules, different benefits, and definitely different paperwork. But don't worry, I'm here to walk you through this transition so it feels less like navigating a maze and more like following a clear roadmap.

The truth is, you can technically keep your Marketplace plan even after becoming eligible for Medicare. But should you? That's what we're going to explore together. And here's the important part switching to Medicare isn't automatic, even when you turn 65. You've got some decisions to make and steps to take.

The Big Picture

Let's start with the basics. When we talk about the Marketplace to Medicare transition, we're essentially talking about moving from coverage under the ACA to federal Medicare insurance once you're eligible. Most people qualify when they turn 65, but others might be eligible earlier due to disability (after 24 months of Social Security disability benefits), ALS, or end-stage renal disease (ESRD).

Here's something that catches a lot of people off guard: while you're not required to cancel your Marketplace plan manually until you choose Medicare, those helpful subsidies you've been getting the advance premium tax credits end when you become eligible for premium-free Medicare Part A. It's like the government saying, "Okay, you've got Medicare now, so we'll stop helping with Marketplace costs."

Item	Details
Initial Enrollment Period	7 months (3 before + birth month + 3 after age 65)
Cancellation Required?	Yes Medicare doesn't cancel your Marketplace plan automatically. You must act.
Subsidy Impact	Advance Premium Tax Credits (APTC) stop once eligible for premium-free Medicare Part A.
Penalties for Delaying Medicare	Late enrollment penalties apply if you delay signing up for Part B unless covered by employer/group plan.

Why This Transition Matters

Let's be real about the financial side of things. If you keep both a Marketplace plan and Medicare at the same time, you're essentially paying for two premiums and getting no extra benefit. It's like buying two umbrellas when it's only raining on one side of you unnecessary expense with no added protection.

And here's where things can get a bit tricky if you're receiving financial help through premium tax credits on your Marketplace plan, those stop when you become eligible for Medicare Part A, regardless of whether you've actually signed up for Medicare yet. If you don't report this change correctly, you might end up owing money back when you file your taxes. Trust me, that's not a pleasant surprise to get in April.

I always tell people if you keep your Marketplace plan without updating your status after becoming eligible for Medicare, you could end up paying full price for that plan and potentially having to repay those tax credits you received. Plus, you're still only getting the same level of coverage. It's a bit like paying for first-class seats but staying in coach you're spending more for the same experience.

Is Medicare Better for Seniors?

For many people, Medicare actually ends up being more cost-effective than staying on the Marketplace once you hit 65. Let's break down what Medicare offers:

Medicare isn't just hospital and doctor visits it's a comprehensive system with different parts:

• Part A: Covers hospital stays, skilled nursing facility care, hospice care, and some home health care
• Part B: Covers doctor visits, outpatient care, preventive services, and medical equipment
• Part C: Medicare Advantage plans that bundle A and B, often including Part D (prescription drugs) and extras like dental and vision
• Part D: Prescription drug coverage

What's really cool is that Medicare also offers ways to save money if you have limited income. Programs like Extra Help (also called the Low-Income Subsidy) can help with Part D costs, and Medicare Savings Programs might help with premiums, deductibles, and copays for Parts A and B. These assistance programs can make a real difference in your monthly expenses.

Of course, there are some situations where keeping a Marketplace plan might make sense. For example, if you're still working past 65 and have excellent employer coverage, you might qualify for a Special Enrollment Period and could delay Medicare without penalty. Or if you pay a premium for Part A and have specific strategic reasons, you might choose to delay.

But here's my advice don't try to figure this out alone. Consider working with a licensed advisor or your local State Health Insurance Assistance Program (SHIP) to really understand the costs and potential penalties involved. They can help you model different scenarios so you can make the best financial decision for your situation.

How to Enroll in Medicare

Ready to make the switch? The first thing you need to know is about your Initial Enrollment Period (IEP). This is a 7-month window that starts 3 months before the month you turn 65, includes the month you turn 65, and ends 3 months after that month.

You can enroll in Medicare several ways:

• Online at SSA.gov
• By phone Call 1-800-772-1213 (TTY 711)
• In person at a Social Security office
• Through the Railroad Retirement Board if that applies to you

Here's something important to note automatic enrollment only happens if you're already receiving Social Security benefits at 65, or you've been getting SSDI for 24 months, or you have ALS or ESRD. Otherwise, you need to actively apply. Don't assume that just because you turned 65, you're automatically covered!

Part	Covers	Cost	Notes
Part A	Inpatient hospital care, skilled nursing, hospice, some home health	Free in most cases	Based on work history (10+ years of Medicare-paid employment)
Part B	Doctor visits, outpatient care, preventives, durable medical equipment	Monthly premium (~$174.70 in 2024)	IRMAA surcharges based on income
Part C	Private plans offering A+B+extras; sometimes includes prescription drugs	Varies	Must maintain Part A & B
Part D	Prescription drug coverage	Varies (often $0-$50/month)	Optional, but very helpful

Canceling Your Marketplace Plan

Okay, so you've decided to make the switch to Medicare. Great choice! Now comes the crucial step of canceling your Marketplace plan. And here's where things can get a bit tricky if you're not careful.

You absolutely must cancel your Marketplace plan yourself it's not automatic. Here's how to do it properly:

1. Go to Healthcare.gov
2. Log into your account
3. Update your Marketplace application status
4. End your Marketplace policy effective the day before your Medicare coverage starts

This timing is crucial you want a seamless transition, not a gap in coverage or overlapping coverage. Think of it like changing shifts at work you don't want to clock out before someone clocks in, but you also don't want to work a double shift by accident.

Here's a pro tip: If other family members are still on the same Marketplace plan, this step should only affect your coverage. In this case, it's often better to call the Marketplace directly instead of doing it online. Trust me, you'll avoid a lot of confusion this way.

Busting Common Myths

There are so many misconceptions about switching from Marketplace to Medicare that it's almost overwhelming. Let's clear up some of the most common ones:

Myth #1: Marketplace plans automatically cancel when you enroll in Medicare. Absolutely not! Your Marketplace coverage will continue unless you actively cancel it. Yes, you'll lose your premium tax credits once you're eligible for premium-free Medicare Part A, but the plan itself keeps billing you. I've seen people get really surprised by ongoing charges months after they thought they'd canceled their plans!

Myth #2: You'll be automatically enrolled in Medicare Advantage (Part C). This used to happen with some insurance companies, but that practice ended in 2018. Now, switching to Medicare Advantage is your choice and requires active enrollment.

Myth #3: Staying on the Marketplace is just as good as Medicare. While Marketplace coverage can be excellent, and the subsidies make it affordable, once you lose those subsidies and add Medicare costs, you might find Medicare is actually the better financial deal. Plus, you don't get double benefits it just creates complications.

What Happens If You Miss Deadlines?

We all make mistakes, and sometimes life gets in the way of important paperwork. But missing your Medicare enrollment deadlines can really cost you.

If you miss your Initial Enrollment Period and don't qualify for a Special Enrollment Period, you could face a late enrollment penalty for Part B 10% extra for every full 12-month period you could have been enrolled but weren't. Ouch! Plus, you'd have to wait until the General Enrollment Period (January through March) for coverage to start, with your new coverage beginning July 1st. That's potentially six months of being uninsured!

There's also another scenario that catches people off guard. If your Marketplace plan has an automatic annual renewal clause and the insurer isn't aware of your Medicare status, they might cancel your plan at the end of the year. This can leave you scrambling to find new coverage with fewer options available.

A Real-Life Success Story

Let me tell you about Beth, a client of mine who navigated this transition beautifully. Beth turned 65 in July and was still working. Her family members who weren't yet eligible for Medicare were covered on her Marketplace plan with subsidies. She decided to switch to Medicare because her HSA contributions needed to stop anyway.

Here's what Beth did right:

1. She contacted Social Security directly to ensure correct timing and confirmation of her enrollment (she was already getting SSDI).
2. She called the Marketplace help line to update her application so that only she was removed from the plan, keeping coverage for her family members.
3. She notified her tax preparer about the partial-year subsidy use, so they could adjust her IRS Form 8962 appropriately.
4. She verified provider networks under Original Medicare and explored Medigap options.

The result? Beth had a completely seamless transition without any subsidy payback issues or coverage gaps. When I checked in with her a few months later, she said the whole process was much easier than she'd expected once she had a clear roadmap to follow.

Her advice to others making this transition? "Call the Marketplace directly when updating your status, especially if other family members depend on your plan continuing. It saves so much confusion!"

Your Action Checklist

Ready to make this transition yourself? Here's your handy checklist:

• Confirm your Medicare eligibility (age 65, disability, etc.)
• Register with Social Security during your Initial Enrollment Period, even if you weren't already receiving benefits

• Report your Medicare start date to the Marketplace
• End or exit your Marketplace plan (consider calling if others are still on the plan)

• Consider additional coverage through Medicare Advantage (Part C) or Part D if needed

Wrapping Up Your Transition

Think of it like learning to drive intimidating at first, but with the right instruction and a bit of practice, it becomes second nature.

The key is taking action early ideally within your Initial Enrollment Period. This protects you from potentially costly mistakes like late penalties, having to repay subsidies, or experiencing gaps in your healthcare coverage.
