Winner

Go Medigap (eHealth)

  • Quoted prices from $170 to $185/month
  • Coverage in all 50 states
  • Helpful online resources

Operating since 2005, the company known as GoMedigap (now part of eHealth) w orks under the name eHealth, though it is the same site. The company offers a comprehensive range of Medicare Supplement Plans, serving over 35,000 seniors nationwide. While the slower quote process and potential hidden fees are concerns, the impressive user reviews and reputation of the company make up for those concerns completely. eHealth's Rate Watch feature, proactive monitoring of premiums, and ethical practices contribute to its "A+" rating from the BBB and numerous 5-star reviews, earning it a trustworthy rating.

Aetna

  • Quoted prices from $122.62 - $142.92 / month + annual deductible of $198
  • Sells its own insurance
  • Guaranteed rates for 12 months

Aetna, with over 160 years of insurance experience, is a reliable choice for Medicare Supplement Plans. The company offers next-day coverage initiation for Plan G, stands out for transparent online quotes, and provides competitive premiums. However, detailed plan information is lacking online, requiring a call for accurate pricing information. Aetna serves 21 states, and its customer service is available 7 days a week. While the pricing is competitive, some transparency issues and customer complaints impact the overall rating. Still, they remain a competitive option overall.

If you or a family member is nearing 65 - or if you'll qualify for Medicare Parts A and B for other reasons - now's a great time to explore extra coverage for your Medicare. Original Medicare covers a lot, but it doesn't pay for everything. That's where a Medicare Supplement plan - often called "Medigap" - can help pick up the costs that slip through the cracks. Take a moment to compare benefits, premiums, and enrollment windows now so you're set up before bills arrive.

These plans help close the gap left by Medicare - the roughly 20% of costs it doesn't cover - so you pay less out of pocket and feel more confident about your coverage. They act as a safety net for copays, coinsurance, and deductibles, and you can choose options that fit your budget and health needs.

Medicare Supplement plans are labeled by letters to tell them apart, and that alone can be confusing. The lineup keeps changing, so it's no wonder people get turned around when a longtime favorite like Plan F - closed to new enrollees after January 1, 2020 - gives way to Plan G, which offers similar benefits but leaves you with an annual deductible. Keeping up with these shifts helps you focus on the coverage you truly need and avoid what you don't. It's also smart to revisit your options each year - and ask questions - so your coverage keeps pace with your health and budget.

As you plan your Medicare path, keep the guaranteed-issue window on your radar - the six months after your 65th birthday when you can enroll in a Medicare Supplement plan with nothing more than paying the premium. It's a brief but important opportunity, and missing it may mean medical underwriting, fewer options, or higher costs later. Set a reminder now so you don't let that window slip by.

In practical terms, you can't be turned away for existing conditions during the six-month window, but smokers should expect to pay more. After that grace period ends, insurers can dig deeper into your health history - for example, asking about diabetes or heart disease - and those details may raise your premiums or limit which plans you can choose. It's wise to review your options before the deadline so you're ready for any added questions.

Buying a Medicare Supplement plan usually comes down to two routes: go straight to an insurance company or work through a broker. Sticking with a carrier you already know can feel simple - you keep a relationship you trust and may find the lower rates or reliable claims support you're used to. A broker, on the other hand, opens up the wider market so you can compare plans and prices side by side, including quotes from your preferred insurer. Before you choose, think about whether you want a single familiar contact or a broader view of options, and take a moment to weigh customer service, financial strength, and how rates have changed over time.

Whether you go through a broker or buy directly from an insurer, the real key to choosing a Medicare Supplement plan is doing your homework. You can start by browsing different carriers' websites to get a sense of pricing and plan options, but Medicare rules mean these policies must ultimately be sold in person or over the phone, so you'll need to speak with a representative to complete enrollment. As you compare, jot down quotes and ask about household discounts and underwriting rules - identical standardized benefits can be priced very differently from one company to the next.

If you're not sure where to start with your Medicare Supplement Plan, we've put together a few things that might help you narrow down your options:

Medicare Supplement Plan FAQ

What is Medicare Supplement Insurance?
Medicare Supplement Insurance is additional coverage beyond traditional Medicare. Also known as "Medigap", these plans cover some or all of the expenses that aren't covered by your basic Medicare benefits.
Why do I need Medicare Supplement Insurance?
Original Medicare only covers 80% of most medical expenses. The remaining 20% can get extremely costly, especially if you have a long hospitalization or a condition that requires specialized treatment. Medicare supplemental plans can ease the financial burden, kicking in where Medicare stops and reducing your out-of-pocket costs.
Is it expensive to get Medigap coverage?
That depends entirely on the plan you select. Will you choose a high-deductible plan with lower premiums, or is it worth it to you to pay more in premiums to pay nothing when you have a medical expense? It also is heavily influenced by your particular situation: where you live, if you're a smoker, male vs. female, your age, and so forth. For Plan G coverage (the most popular of the Medicare supplemental plans), expect monthly premiums in the $110 - $160 range.
What are some of the biggest differences among the different plans?
It can be confusing at first, partly because they're all identified by letter names (for example Plan A, Plan B, and so on) - and they're often mistaken for the similarly-named components of Medicare itself (Part A, Part C, and more). Again, the main differences relate to the trade-off between deductible amounts and premiums: pay more upfront to spend less later, or vice-versa. Plan benefits are standardized, however, so whether you choose a Plan M with one insurer or another, your coverage is the same.
How should I know which provider or service to use to get started with a plan?
While your coverage is the same regardless of which provider you use, premiums vary. It's a good idea to speak with a few companies, or with a broker that can give you quotes from several insurers to compare. Also, each company offers a different package of "extras" to complement your Medigap coverage. Some services will keep an eye on your premiums and let you know if you're going to experience a significant increase - and they'll even recommend a new insurer if they find one that's better suited to your needs.
Will the premiums change from year to year?
Unfortunately, yes. Just like any other form or insurance (such as auto, medical, homeowner's), your Medicare supplement insurance premiums may change. Insurers may lock in your rate for a year or two, but you should be prepared for an increase in the future. There are a few providers who have a strong track record for keeping increases infrequent and small.
Can I get Medicare Supplement Insurance if I'm on disability?
That depends. While some states require Medigap plans to be available for disabled individuals under the age of 65 (the age that standard Medicare eligibility starts), there's no corresponding federal law. And, many states that permit Medigap coverage for the disabled also have restrictions that don't apply for the 65-and-up plans. You should speak to a Medicare Supplement Plan advisor to learn about the options in your state of residence.
Is Medicare Supplement Insurance legitimate?
Not only is it legitimate, it's an important component of many seniors' healthcare benefits and financial planning. Of course, you should be careful to choose a reputable provider and work with an agent or referral service that takes the time to understand your needs and explain all of the available options. There's a limited window of opportunity to sign up for a Medigap plan without having to submit medical reports, so it is recommended that you begin doing your research well before your 65th birthday.
