Tips for Choosing the Right Medicare Supplement Insurance Plan

The three most significant considerations for finding the best Medicare supplement insurance are: price transparency, customer service and pricing methods.

Top tips:
  • Sign up for a Medicare supplement policy during open enrollment
  • Shop around to compare prices and programs
  • Don’t confuse Medigap insurance with Medicare Advantage

How to Choose Medicare Supplement Insurance

Look for price transparency: If you can determine premium costs with no hassles, it’s a sign you’re dealing with a reputable company. You should quickly obtain quotes over the phone, online or in person.

Consider customer service processes: Look for a company with a streamlined process for buying Medicare supplement insurance. Consider your preference for meeting face-to-face in a local office, discussing policies over the phone or using online chat.

Compare exclusions and deductibles: Every plan differs in terms of coverage and the deductible you must pay before these policies begin paying benefits. A high-deductible Medigap plan has lower monthly premiums, but you m just consider the coverage option that makes sense for you.

Understand that pricing models affect future premiums: Medicare supplement insurance is priced using three rating systems. Consider how each model affects future costs. Ask insurance representatives about the method used for each policy you’re interested in buying.

  • Community-rated charges the same monthly premium to all policyholders. Premiums may rise due to inflation, but not age.
  • Issue-age-rated policies are priced based on age when the coverage begins. Premiums do not rise due to age and cost less if you purchase when younger.
  • Attained-age-rated premiums are based on your age when you apply for the insurance. The cost may be low at first but rises with age.

What is Medicare Supplement Insurance (Medigap)?

Medicare is government-funded healthcare insurance for Americans age 65 and up. Plans include deductibles and copays, so the insurance doesn’t cover 100% of medical costs. Private insurance companies sell Medicare supplement plans to limit costs associated with Medicare Part A and Part B.

You are eligible to buy Medicare supplement insurance during your Medigap Open Enrollment Period if you are enrolled in Medicare Part B. Medicare supplement plans are regulated, and plan benefits are the same in all but three states. Costs and the number of plans vary by insurer, however.

Medicare Part A Deductible and Co-insurance
2021 to 2023 Increases
Cost Sharing Amount 2021 2022 2023
Inpatient hospital deductible $1,484 $1,556 $1,600
Daily co-ins. for 61st-90th day $371 $389 $400
Daily co-ins. for lifetime reserve days $742 $778 $800
Skilled Nursing Facility co-ins. $185.50 $194.50 $200.00

Part B coinsurance is typically 20% of the cost for doctor visits, hospital inpatient services, outpatient therapy and durable medical equipment. Medicare Part D is a prescription drug plan with varying copays and deductibles.

We recommend shopping around using a Medicare expert like United Medicare Advisors to compare plans. There are 10 standard Medigap plans, and there’s not one that’s best for all situations. Massachusetts, Minnesota and Wisconsin provide Medicare supplement policies for residents.

Compare prices for Medicare supplement insurance

What about Medicare SELECT?

Some states also offer a Medigap policy called Medicare SELECT. While these plans typically cost less compared to other Medicare supplement plans, you must use only certain hospitals and doctors. Unless you require emergency services, these plans pay no benefits if you go out of the network.

Medicare SELECT is budget-friendly, but covers less

When to Buy Medicare Supplement Insurance

What is the biggest mistake Americans make regarding Medicare supplemental insurance? Not enrolling on time.

A spokesman with the Social Security Administration told us, “Everyone thinks they have enough coverage when they’re 65 if they’re working or if they have insurance through their spouse. They don’t think they have to sign up. Then later, they find out they have missed their open enrollment period.”

If you are retired, buy Medicare supplement insurance within six months of the date you turn 65. You’re required to enroll in Medicare Part B to buy a policy. If you have insurance through your employer, you can wait to enroll in Part B when you are retired.

If you have a preexisting health condition or disability, buy Medigap coverage during your six-month enrollment window. You’ll pay the same premium as those who are in good health until the enrollment period expires. Miss the open enrollment window, and you will likely pay more for coverage — if you can buy a policy at all. You can still buy a Medigap policy under some circumstances defined by guaranteed issue rights.

Don’t miss the enrollment period if you are retired

Changes for Medicare Supplement Insurance After 2020

Medicare supplement plans stopped selling Plan C and Plan F to new policyholders. This rule went into effect in 2020 due to the Medicare Access and CHIP Reauthorization Act. MACRA mandates that new Medigap plans can’t cover the Part B deductible.

You can keep the coverage if you enrolled in either plan or the high deductible version of Plan F before January 1, 2020. You may still be able to buy Plan C and Plan F if you were Medicare-eligible before January 1, 2020, but did not enroll.

Frequently Asked Questions about Medicare Supplement Plans

When should I buy Medicare Supplement Insurance?

Put the first day of your Medigap open enrollment period on your calendar. This six-month window kicks off the month you turn 65. You must also enroll in Medicare Part B to be eligible to buy a Medigap policy. You can sign up for any Medicare supplemental insurance during the six months, even if you have a preexisting condition.

You may be able to buy Medicare supplemental insurance after the six-month window. However, insurers may increase premiums or deny coverage.

Do I have to purchase Medicare supplement insurance?

You are not required to buy Medicare supplement insurance. The most recent data shows around 13.5 million people enrolled in a Medigap plan.

Without a Medicare supplement plan, you’re responsible for out-of-pocket costs that can cost thousands of dollars. Health care expenses can eat into your retirement savings, so buying coverage is probably a good financial move.

What if I’m 65 or older and still using my employer coverage?

If you are one of the millions of Americans working after age 65, your employer’s health insurance coverage may be sufficient. Medicare supplement open enrollment starts when you enroll in Medicare Part B. You can delay enrollment until you retire.

If you aren’t sure if you qualify for coverage, start by finding out if you are eligible for Medicare.

How much does Medicare supplemental insurance cost?

We found policies ranging in price from less than $100 per month for basic coverage to thousands for maximum protection. There’s no average cost for Medigap insurance because of many factors, such as your location, age and needs.

A ballpark figure for Medicare supplement insurance premiums is around $165 per month for standard coverage. However, the more supplemental insurance you want, the higher the cost.

Can I get a discount on a Medicare Supplement Insurance?

Yes. Some plans offer discounts if you’re married. You may be able to cut your rate if you’re a nonsmoker. Some companies give price breaks if you pay annually or via electronic funds transfer. Even if the website or brochure you’re studying doesn’t mention anything about discounts – ask.

Are all 10 Medicare supplemental insurance plans the same in every state?

While there are 10 different plans in most of the U.S., federal law mandates that each plan carries the same coverage. For example, Plan K in New York offers identical benefits to Plan K in New Mexico.

Where else can I turn for more information?

Click on the SHIP Locator button on the State Health Insurance Assistance Program website to get help with Medigap insurance. Click on your state to see the phone number and state office website.


Bottom line:
Medicare supplement insurance coverage is one of the most critical health and financial decisions you make for retirement.

You may start looking at policies with one or more of our picks for best Medicare supplement insurance companies.

Talk to a representative and know your policy options before you buy Medigap insurance. Get the costs and benefits in writing. With transparent pricing, you won’t buy more coverage than needed or be surprised by steep increases later.

Buying a Medicare supplement policy can be complicated. There are many choices available, and the right plan can significantly reduce medical costs. It’s ideal to have a friend or family member review the Medigap policy before you sign up.
