The Basics of Medicare: Original, Advantage, and Supplement

While Medicare coverage is technically provided by the government, private companies assist with administering plans, and also offer their own plans. Additionally, some companies offer Medicare Supplement or Medigap coverage.

Original Medicare is the plan offered by the government. Private companies may add more coverage to the basics.

Plans that provide the coverage of Medicare Parts A & B in one, with Part D sometimes included as well, are called Medicare Advantage. These plans are referred to as Part C and provide an array of added benefits on top of the standard Medicare coverage, such as fitness memberships.

Some plans have no additional premium on top of the Medicare premium you already pay, while others do have an extra premium in return for more coverage options.

Parts A & B provide your medical, hospital, and hospice coverage. Part D is your prescription drug coverage – some Advantage plans include this, while it’s an optional add-on with other plans, it can also be purchased separately. Part D is an important coverage to have if you have to purchase some of the most expensive Medicare drugs.

Original Medicare does pay for COVID-19 testing and treatment.

What is Medicare Supplement? It is an optional policy that you can purchase to fill in some of the gaps left by your overall policy. These include paying coinsurance and deductible amounts and providing coverage for emergency care abroad. Supplement plans are standardized, with most states following a letter-coded system; while many companies may offer the plans, the actual coverage does not vary.

In Massachusetts, Minnesota, and Wisconsin, the lettered plan system is not used, but plans are still standardized.

Some companies offer just Medicare Advantage or only Supplement, while others offer a full range of products.

The Parts of Medicare Coverage

Medicare coverage can be complex on the surface – with all the “parts” and optional coverage it can be difficult to figure out what you already have and what you need. First, we will break down the parts.

Part A is the coverage for hospital care, hospice care, skilled nursing, as well as some home care services. This is the coverage that will kick in if you are hospitalized or need ongoing care either in your home or in a facility. (For more information, read our “Best Memory Care Facilities That Will Accept Medicare“)

Part B covers things like doctor’s visits both preventative and for illness or injury, outpatient care, tests including x-rays and lab work, emergency room, and home care not covered by Part A.

Part C is Medicare Advantage. This is a private company plan that provides all of the coverage of Parts A and B along with some additional services. These plans vary by company, and most companies offer more than one plan as well. These plans may include dental and vision as standard or as an add-on as well.

Part D is prescription drug coverage. These plans can be purchased to tack on to your Original Medicare plan, can be added on to a Part C Medicare Advantage plan, or may be included as part of the Advantage package. Deductibles and copays on these plans vary greatly.

Your Medicare premium pays for Part B (Part A has no cost in most cases); this is known as Original Medicare. When you select a Part C plan, you continue to pay that premium. There may or may not be an additional premium for the Part C plan, depending on which option you select.

A PPO plan, for example, that gives you access to a wider network of providers, usually costs more than an HMO plan. Even $0 Medicare Advantage plans usually offer some benefits above and beyond the basic Plan A & B coverage.

Creating a Medicare plan that is right for you involves selecting the coverage you want and combining it in a way that works for you. If you choose a Medicare Advantage policy, you will find it is a lot like shopping for individual insurance. Provider networks, copays, deductibles, and out-of-pocket limits will vary – as will the premium.

Our Process for Choosing the Best Medicare Companies

There are a lot of Medicare companies out there, but they are not all created equal. In order to choose the best Medicare options overall, we started by removing any company that does not offer all three of the Medicare coverage choices; Advantage, Part D, and Supplement. To be in our top three overall the company has to be a one-stop-shop.

We also looked for companies that offer good plan choices without becoming overly complicated. Having several plans to choose from is great; getting lost in a sea of options can make shopping even more difficult.

As always, our top picks have a good reputation for customer service and reasonable rates that offer good value to their customers. We took into consideration the government’s Medicare plan ratings, the National Committee for Quality Assurance (NCQA) ratings, and our own research to determine value.

Medicare plans vary from state to state. We tried to choose companies that offer coverage in as wide an area as possible, but these picks may not be available everywhere.

Our Top Medicare Company Recommendations

These three companies provide every option under one roof and do it with great service and great plans.

Aetna Medicare

The third-largest health insurance provider in the nation, Aetna is expanded its reach with the recent merger with CVS pharmacies. They have a full range of Medicare products, including both PPO and HMO Medicare Advantage options. The plans are easy to understand and easy to select.

Aetna is rated very well by the NCQA, and although they do have room for improvement in their government rating they perform well overall. With a large network and solid plans, they’re a good choice for all your Medicare needs. (For more information, read our “Aetna Insurance Review & Complaints: Medicare“).

Cigna Medicare

Covering most of the country through state branches and partnerships with local networks, Cigna has a plan for most people. They offer two options for a $0 additional premium Advantage plan in our sample state, as well as a host of other options. They also have a very comprehensive list of Supplement plan offerings.

Our rate tests show that Cigna has a range of prices on their products, which means that regardless of your budget, they can likely help. They also have a good reputation for a company of this size.

Shopping for Medicare Advantage

Before you start shopping for Medicare coverage, it is important to decide what coverage is most important to you and what your budget is for monthly premiums. If you have decided you would like to go with an Advantage plan rather than Original Medicare, you can start the next step. You may also have to consider special health needs, such as finding the best Medicare diabetic supply company.

The next thing to decide in order to narrow things down is what sort of network you prefer. If you want access to the most providers, you should shop PPO plans, but if you are ok with a limited network in return for lower premiums, HMOs are the way to go. Your budget will have a bearing on that decision as well.

Most insurance companies allow access to a provider search where you can determine if your current doctors are in-network for the plans you are considering. You should also do a search on any regular medications you take to find out what coverage is offered on a Part D plan you are considering, whether part of your Advantage plan or separately.

Once you have the basics down, be sure to compare Part C plans on what extras they offer for the added premium. Is dental included? Vision? What about hearing coverage? Look for added coverage and benefits as well as comparing copays, deductibles, and premiums.

Shopping for Medicare Supplement

Medicare Supplement insurance may be a little easier to shop for since the plans are standard. Take a look at the chart below that outlines all of the plans, what they cover, and what they do not.

Medicare Supplement Plan Comparison

These plans are available in most states, although Massachusetts, Minnesota, and Wisconsin use a different set of standard plans. Both Plan F and G have high deductible options as well.

Bear in mind, if you are looking for the best Medicare Plan F company, that new rules mean you may not qualify for Plan F. It is not available to those that were newly eligible for Medicare as of January 2020.

The most important things to consider with Medicare Supplement are the company’s reputation and how much out-of-pocket cost you are willing to take on versus monthly payments for coverage. If you aren’t worried about co-pays and deductibles, you may not need a Supplement plan at all.
