Thinking About Switching from Medicare Advantage to Medicare Supplement?

So, when you first enrolled in Medicare you chose a Medicare Advantage plan. It worked well for a while but after spending more than you first thought on co pays and coinsurance, you star to wonder would a Medicare Supplement plan work better for me? You are not alone. 

This guide is for Medicare beneficiaries, especially those who want freedom in going to any doctor or hospital that accepts Original Medicare, fewer out-of-pocket costs, and more predictability in their healthcare. Today, we’ll walk you through how and when to make this change, how to do it smartly, and what not to overlook so you have a seamless transition. 

Let’s break it down clearly—no jargon, no fluff. 

What’s the Difference Between Medicare Advantage and Medicare Supplement?

Medicare Advantage: The All-in-One Alternative

Medicare Advantage (Part C) is more like Health Insurance where it is a package deal that includes hospital, medical, prescription drug coverage into one plan—usually with lower monthly premiums and a max out of pocket. 

Medicare Supplement (Medicare Supplement Insurance): Pay Now, Save Later

Medicare Supplement helps cover the “gaps” in Original Medicare, like copays, coinsurance, and deductibles. It’s usually paired with Medicare Parts A and B and usually requires a separate Prescription drug plan. 

Why People Switch

Many folks start with Medicare Advantage to save money early on. But as their healthcare needs grow, the flexibility and coverage that comes along with a Medicare Supplement plan becomes more appealing. 

Real-Life Example: Meet Carol

Carol is 67 and started with a $0premium Medicare Advantage HMO plan. It seemed perfect—until she needed knee surgery and a bunch of rehab. Her copays and rehab costs added up quickly. Her biggest frustration? Everytime she went to physical therapy they charged her a 50 dollar co pay. 

Now she’s looking into a Medicare Supplement plan. But there’s a catch—she’s outside her guaranteed issue window. That means she may have to answer health questions(in most states) and could be denied or charged more for pre existing conditions. 

How to Switch from Medicare Advantage to Medicare Supplement (Without Regret)

1. Know Your Timing

The best time to get a Medicare Supplement plan is during your Medicare Supplement Open Enrollment Period. This is a one-time 6-month window that starts the month you’re both 65 and enrolled in Medicare Part B.

Already missed that window? You can still apply, but insurers can consider your health.

This does not apply to guaranteed issue states like for example NY

Pro Tip: Some states offer “trial rights” or limited guaranteed issue periods if you’re switching from a Medicare Advantage plan after trying it for the first time.

2. Apply for Medicare Supplement plan First Drop Medicare Advantage Second

Don’t cancel your current plan until your Medicare Supplement policy is approved. 

3. Add a Standalone Part D Plan

Medicare Supplement plans don’t include prescription drug coverage. You’ll need a standalone prescription drug plan—and you must enroll during the correct enrollment period to avoid penalties. This is usually done during the Annual Enrollment Period however if someone qualifies for a special election period, this can also be done during the year. 

4. Ask About Underwriting

Outside your open enrollment, you may need to answer medical questions. Work with an agency (like ours!) that can go over the underwriting with you and see if it makes sense to make a change.
