With the elimination of Plan F for new Medicare subscribers as of January 1, 2020, Medicare Supplement Plan G has moved into the spot for most comprehensive coverage out of available Medicare Supplement Plans. Also known as Medigap, Medicare Supplement Insurance is sold to those with Original Medicare who want to reduce their out-of-pocket expenses on coinsurance, copayments, and the Part A deductible, among other plan factors.

Medicare Plan G standardized coverage includes paying for the Part A coinsurance up to 365 days after Medicare benefits are used up; the Part B coinsurance or copayment; blood up to the first 3 pints; the part A hospice care coinsurance; skilled nursing facility care coinsurance; the Part A deductible, the Part B excess charge, and 80% of foreign travel health coverage.

While Medicare Supplement Plans are standardized in terms of coverage across 47 states, there are still important differences in the costs and companies that offer these plans. You’ll want to carefully research companies that offer Plan G in your area so you get not only the best deal but also high-quality customer service.

Best Medicare Supplement Plan G Companies of 2020

Aetna: Best for Price Transparency

Aetna

Aetna

Pros
  • Offers both Plan G and high-deductible Plan G

  • Household discounts available and listed in quote

Cons
  • Not available in seven states and the District of Columbia

  • High-deductible Plan G not offered in all areas

As an insurance provider, Aetna has been in business since 1853 and has more than 22 million members in its health and benefit plans. The company's long track record and both traditional and high-deductible benefit offerings earned Aetna a spot on our best Medicare Supplement Plan list.

Aetna doesn’t offer Medicare Supplement Plans in all states. You can’t purchase its plans in Alaska, Connecticut, the District of Columbia, Hawaii, Maine, Massachusetts, New York, and Washington. It also doesn't offer high-deductible Plan G in all areas. Aetna's online quote tool is easy to use, and you can easily compare its Plan G offerings versus other Medicare Supplement Plan costs.

Aetna offers a household discount when you and another member of your household (such as a partner or spouse), subscribe to Aetna’s Medicare Supplement Plans. You can see the household discount along with your initial quote. In the quote we received, the household discount saved us $7 on the original Plan G and $2.72 on the high-deductible plan option. The monthly premium we were quoted was $160.52 for Plan G, which was on the lower end of the Medicare Plan Finder range of $128 to $434 for the search area.

Mutual of Omaha: Best for Educational Tools

Mutual of Omaha

Mutual of Omaha

Pros
  • Features comprehensive educational library

  • Serves 50 states

Cons
  • Price quote was on the higher estimate side

  • Doesn’t offer high-deductible plan

Mutual of Omaha has provided insurance policies in the United States since 1909. Today, it serves 50 states, making it one of the most comprehensive companies we reviewed in terms of coverage.

The company's website features a primer on Medicare Supplement insurance to help you establish basics like comparing different plans and how the company works with Medicare to supply your benefits. The site also offers a side-by-side comparison of different Plans (such as Plan F versus Plan G). It gives you some key descriptors that can help you identify if Plan G is a good fit for you, such as “I’m price-conscious, but can afford my annual deductible.” You can also choose from two views for your quote: per month or per year.

You can quickly obtain a quote through Mutual of Omaha's quote finder, which offers you a 7% household discount. It also offers an e-application that you can start online and return to later. When you do apply, there are highlighted vocabulary areas throughout the application that define potentially unfamiliar terms.

The price we were quoted was on the higher side of the average Medicare estimate. For one zip code we searched, the Medicare plan finder provided a premium range estimate of $98 to $221, and we were quoted a $220.98 premium (before a potential household discount).

Bankers Fidelity: Best for Easy Application

Bankers Fidelity

Bankers Fidelity

Pros
  • Household discounts available

  • Can quickly apply on its EApp portal

  • Site features a Knowledge Center for in-depth explanations and definitions

Cons
  • Must provide your contact information before you can get a premium quote

  • Plans sold in only 34 states

Bankers Fidelity has been in operation since 1965 and offers fast online quotes. While we had to provide contact information to obtain the quote, the process was otherwise seamless and allowed us to compare Plan G against its other available policies. One of the key features we most liked was the company's EApp mobile application, where you can quickly apply for Plan G coverage. You can obtain this EApp after speaking with an agent, who can also also provide a paper copy, if you prefer.

In addition to the EApp, the company also has a policyholder portal. There, you can check the status of your claims as well as obtain contact information should you have a question on your coverage. While Bankers Fidelity is licensed in 46 states and the District of Columbia, it only offers Medicare Supplement plans in 34 states. Some of the states where the plans aren’t available are California, Connecticut, Minnesota, Oregon, Vermont, and Washington.

We also liked Bankers Fidelity's “Knowledge Center,” a separate page on its website that explained Medicare Supplements more in-depth. It also defined more unfamiliar terms, which would help if you are new to your Medicare research.

While Bankers Fidelity doesn’t offer a high-deductible Plan G, its quoted rates were on the lower side of the averages we saw. For example, on the plan finder, Medicare quoted a range of $90 to $357 for one zip code searched, and we were quoted a rate of $135.16 for Plan G.

Humana: Best for Discounts

Humana

Humana

Pros
  • Offers both Plan G and high-deductible Plan G

  • Offers multiple discounts to those who qualify

  • Medicare Supplement Plans offered in 50 states and District of Columbia

Cons
  • High-deductible Plan G not offered in all locations

  • Plan G not offered in all states

Medicare doesn’t require Medicare Supplement companies to offer Plan G. In 2018, an estimated 66 percent of all insurance companies that sold Medigap sold Plan G.

Humana was founded in 1961 and has risen to become the third-largest health insurance provider in the United States. It offers Medicare Supplement plans in all states and the District of Columbia. However, it does not offer Plan G in all states, so it’s important to search by your zip code to ensure you can obtain Plan G from Humana.

In terms of premium pricing, Humana was on the lower side based on our research. The quote estimates we were given from the Medicare plan finder were $135 to $491 for Plan G and $47 to $110 for the high-deductible plan. Humana offered us $169.58 per month for Plan G with an online discount and a high-deductible Plan G was $63.14 with an online discount.

A discount is given if you sign up via its online portal. If you are in a guaranteed-issue period, you may also qualify for Humana’s “Preferred” rates, which are calculated by age and gender. The “Standard” rate is subject to medical underwriting for those outside a guaranteed-issue period and was usually $25 to $30 more per month compared to the Preferred rate.

Education and plan information was easy to find on the Humana website. The navigation is clean and user-friendly—another reason it made our list.

UnitedHealthcare/AARP: Best for Comparison Tools

UnitedHealthcare/AARP

UnitedHealthcare/AARP

Pros
  • Offers a downloadable Medicare Supplement Plan Comparison Guide

  • Operates in 50 states and the District of Columbia

  • Multiple discounts including enrollment and household discount

Cons
  • Does not offer high-deductible Plan G

  • Cannot qualify for enrollment discount past age 81

AARP Medicare Plans through UnitedHealthcare combine two of the best-known names in the insurance and elderly care business. It currently enrolls 4 million Americans in its Medigap plans, which is more than any other individual company that offers Medigap. UnitedHealthcare has been in operation since 1977, and its strategic partnership with the AARP began in 1997.

Through this partnership, UnitedHealthcare and the AARP have developed a variety of educational tools, and the website is a blend of education and price quote and pricing tools. We especially liked the Plan Comparison Guide, which featured easy-to-read graphs and plan comparison features. The guide placed each Medigap plan into a different category to guide decision-making. For example, Plan G falls into its “Higher Benefit Level, Higher Premium” category.

In terms of pricing, the Medicare Plan Finder quoted us a premium range of $107 to $448 for a 70-year-old male who doesn’t use tobacco. Our estimated monthly rate from UnitedHealthcare/AARP was $138.18—but we were reminded the premium could be $495 or a “Level 2” rate if we used tobacco.

UnitedHealthcare/AARP also offers an “Enrollment Discount,” which is rated by age. For those age 65 without certain chronic medical conditions or a history of smoking, this discount may be as high as 39%. There's also a household discount if another member in your household signs up for a Medigap plan as well.

Cigna: Best Extras/Perks

Cigna

Cigna

Pros
  • Provides additional services with membership

  • Offers household and online discounts

  • Operates in 50 states and the District of Columbia

Cons
  • Requires several webpages of questions before obtaining a quote

  • Must share name and e-mail to obtain an online quote

Cigna is the result of a 1982 merger of two companies who’ve provided insurance for more than 150 years, making it a longstanding presence in the insurance marketplace in the United States.

Receiving an online quote from Cigna took longer than most other companies we reviewed. We were asked to provide an age and gender, if we were in a guaranteed-issue period, our e-mail address, and more. Each question had a new webpage, so it seemed like more steps to get through, although these questions likely provide a more accurate quote.

Cigna offers a 7% household discount if someone in your household enrolls in a Medigap policy as well. You can request a quote for your household member during the quote tool process. It also offers an online discount for signing up online and paying via bank draft.

In terms of pricing, we were quoted a premium price of $149.24 per month for a 70-year-old, nonsmoking man with an online discount in a guaranteed-issue period. Medicare’s Plan Finder for the zip code we tested quoted an average price between $128 and $396, putting Cigna on the lower side of premiums.

Cigna also includes “extras” with each Medigap policy sold. This includes participation in its Cigna Healthy Rewards plan, which provides health and wellness discounts such as savings on home-delivered meals, free trials on home fitness classes, and savings on podiatry services. It also provides access to a 24-hour Health Information Line.

State Farm: Best Agent Network

State Farm

State Farm

Pros
  • More than 19,000 State Farm agents nationwide to provide customer service

  • Bundled discount available

Cons
  • Does not offer high-deductible plan

  • Not offered in all states

State Farm has been in operation for nearly 100 years and was founded in 1922. Today, the company is the largest automobile insurance provider in the United States and also provides insurance products that include Medicare Supplement Plans. It may offer a bundle discount if you currently hold other insurance policies with State Farm.

State Farm doesn’t offer Medigap in all states. You can’t currently obtain coverage in Massachusetts, New Jersey, or Rhode Island.

For the zip codes we searched for pricing, we were quoted a Plan G price of $207.74 for a 70-year old nonsmoking man in a guaranteed-issue period. This was close to the middle of quoted policy prices from Medicare’s Plan Finder, which was between $134 and $437 for Plan G. Once you receive a quote, you can select a plan, which directs you to fill out your information. A State Farm agent will reach out to you with further policy information.

Speaking of State Farm agents, the company has 19,000 offices across the country, which means you can have your questions answered locally by agents familiar with each State Farm product.

How We Chose the Best Medicare Supplement Plan G Companies

When evaluating the best Medicare Supplement Plan G companies, we looked at more than 20 companies that offered plans in at least 30 states across the country. Starting with a comprehensive coverage area was important to maximize the number of possible customers. We evaluated website functionality, premium costs, availability of high-deductible plans, and years in operation as a reflection of company stability. We also took into account cost-saving factors, such as if the company included policy discounts or perks for membership. With all these in consideration, we selected seven plans that consistently performed well in providing Plan G supplements.

How to Shop & Compare Medicare Plan G Plans

You can “shop” for Medicare Plan G coverage in your own home thanks to online searching and plan comparison tools. Here are our steps to help you find the best Plan G for you:

Step 1: See which Medicare Supplement Plan Gs are available in your area.

You can do this by visiting Medicare.gov’s Plan Finder or go to individual insurance companies' websites and search for Plan G. Some insurance companies may not offer the high-deductible Plan G, so you’ll have to look at the plan offerings carefully.

If you live in Massachusetts, Minnesota, or Wisconsin, these states standardize their Medigap plans differently. You won’t be able to purchase Plan G if you live in these states because they have their own Medigap plan structure. 

Step 2: Compare the difference in cost among plans.

Because Plan G coverage is standardized, the true differences are in cost and company. Some companies will offer discounts on their website for varying factors, including if members of your household sign up for a plan or if you pay via automatic bank draft.

Step 3: Consider talking to a broker or consultant.

It’s understandable you may still have questions regarding plan selection. For general advice, you can contact your State Health Insurance Assistance Program (SHIP). This is a free service offered in each state that offers unbiased counseling and assistance.

You can also contact an insurance broker or consultant in your area. You can find these through insurance company websites or by word of mouth from friends and family who also have Medicare supplement insurance.

Step 4: Sign up 

Most Medicare Plan G companies will offer you the ability to sign up online, via phone, or by mailing in paperwork. The choice is truly up to you in the signing-up process. It should give you an explanation of your benefits when you sign up and inform you of when your insurance coverage will begin.

The best time to sign up for Plan G is when you sign up for your Medicare benefits. You have a six-month “guaranteed-issue” period where a Medicare Supplement Plan company can’t decline your coverage based on pre-existing health conditions.

To aid you in your search, we’ve reviewed Part G Plans from 25 different insurers. We took into account the insurer’s coverage area, ease of obtaining a plan quote, website navigability, if the plans offer high-deductible and traditional coverage, and quality of educational content.

How Is Medicare Plan G Different From Plan F?

Medicare Plan F was formerly the most comprehensive Medicare Supplement Plan offered. However, as of January 1, 2020, Medicare no longer allows insurers to sell Plan F to new Medicare subscribers. As a result, Plan G is now the most comprehensive coverage, offering eight of the nine benefits available through Medigap.

The main difference in the two plans is that Plan F includes coverage for the Part B deductible while Plan G does not. For 2020, the Part B deductible was $198. Insurers offer both as high-deductible and traditional plans.

What Is a High-Deductible Medicare Plan?

Insurers offer Plan G as a high-deductible Medicare Supplement Plan in some areas. A high-deductible plan means you’ll pay for all your Medicare-covered costs until you reach a certain amount. For 2020, the deductible for the high-deductible plan was $2,340. After you reach this amount, your Plan G benefits kick in.

The high-deductible plan has trade-offs compared with a traditional plan. The high-deductible plan typically has a lower monthly premium. However, you will pay more out-of-pocket before the plan kicks in. Some subscribers prefer the high-deductible plan because it allows them to know what expenses to expect for the year.

Do I Want a Regular or High-Deductible Plan G?

Some people like a high-deductible Plan G because it protects them against large out-of-pocket costs, yet it doesn’t have a high premium. Others like the initial cost-savings of a regular Plan G.

Is Plan G the Best Medicare Supplement Plan?

The best Medicare Supplement Plan depends on your health care needs and what you can afford. Medicare Plan G is currently the most comprehensive Medicare Supplement plan in terms of the coverage it offers. If you desire stability and knowing what to expect from your health care costs (and if you can afford the premium), Medicare Plan G may be the best option for you.

What Is the Average Cost for Medicare Plan G?

The cost for Plan G can vary based on the region where you live. Insurers take into account your health and age, cost of living, and the cost of health care in your area when determining premiums.

While there isn’t more recent data on the average cost of Plan G, we found a wide range of costs while conducting our research. According to Medicare’s Plan Finder Website, here are some of the average costs for a 65-year old man who doesn’t smoke:

  • New York City: Plan G is $268 to $545; High-deductible Plan G: $69 to $91
  • Tampa, Florida: Plan G is $176 to $263; High-deductible Plan G: $52 to $92
  • Houston, Texas: Plan G is $128 to $434; High-deductible Plan G: $36 to $86
  • Albuquerque, New Mexico: Plan G is $105 to $355; High-deductible Plan G: $30 to $59
  • Sacramento, California.: Plan G is $115 to $248; High-deductible Plan G: $38 to $61

These costs can vary by company, your overall health, and if you are in a guaranteed-issue period.
