How to find the best Medicare Advantage plans

By Posted :

People who qualify for Medicare, the government insurance program that covers more than 44 million seniors, have two coverage options. 

You can choose between:

  • Original Medicare, which is offered by the federal government and includes hospital and medical insurance. 
  • Medicare Advantage, which is provided through a private insurer and includes both hospital and medical insurance, as well as likely offering prescription drug and supplemental benefits. 

Original Medicare has been around since 1965 and includes Parts A and B. It doesn’t have prescription drug benefits, but you can get a separate Part D prescription drug plan. 

Medicare Advantage, also called Part C, hasn’t been around nearly as long. About one-third of Medicare beneficiaries have a  and that’s expected to rise in the coming years as more private insurers offer plans. 

The most common type of Medicare Advantage plans are health maintenance organization (HMO) plans, though insurers also offer other types of plans like preferred provider organization (PPO) plans. 

Most Americans have more than a dozen Medicare Advantage plan choices. To help people compare plans, the Centers for Medicare and Medicaid Services (CMS) issues star ratings each year to measure each plan’s quality. The top plans get five stars.

When looking for a Medicare Advantage plan, a good idea to start is looking at five-star plans. Here's what you need to know about five-star Medicare Advantage plans, a breakdown of the top plans and key things to consider before choosing one.


What are five-star Medicare Advantage plans?

Medicare rates plans from one to five stars based on several factors.

The agency uses information from healthcare providers, member satisfaction surveys and the health plans themselves to determine the ratings. Medicare rates Medicare Advantage plans on up to 45 different quality and performance measures, including:

  • Breast cancer screening

  • Colorectal cancer screening

  • Diabetes care

  • Older adult care

  • Care coordination

  • Customer service

  • Health plan complaints 

  • Members choosing to leave the plan

  • Promptness of appointments and care 

  • Claims appeal process speed

A five-star rating indicates a high-quality, high-performance plan. For 2020, just under 5% of Medicare Advantage plans with prescription drug coverage received a five-star rating. Nearly 11% of Medicare Advantage beneficiaries with prescription drug coverage are in five-star plans. About 18% of Medicare Advantage plans (31% of members) with prescription drug coverage received 4.5 stars and 29% received four stars (39% of members).

What to think about when choosing a Medicare Advantage plan

While Medicare's rating system can steer you toward plans that rank highly on several quality and performance measures, it's still important to do your own research and find a plan that aligns best with your particular needs.

When comparing plans, pay close attention to what healthcare providers and hospitals are in the network. If you already receive care from a specific provider, double-check to make sure he or she is considered in-network under the plan. Also, call your doctor's office to make sure the provider accepts the plan before enrolling. Some providers may not accept specific Medicare Advantage plans. 

Doing this extra legwork is important. Otherwise, you may incur extra costs for going out-of-network or have to switch to another provider who is within the plan's network or accepts this insurance.

Also, look at the:

  • Monthly premiums, which is what you pay for the coverage. 
  • Deductibles, which is what you pay for health care services before the plan kicks in money.
  • Coinsurance, which is your portion of the health care services costs after you reach your deductible. 

Some plans may offer a lower monthly premium in exchange for a higher deductible and coinsurance. Some plans may have a high out-of-pocket maximum, which is the most you'll pay for covered services each year. 

For 2020, Medicare has set the out-of-pocket cost limit at $6,700 for Medicare Advantage plans. However, some plans may have a lower out-of-pocket maximum, while some may be right at this threshold. You’ll want to weigh all of these costs and figure out whether you’d prefer to pay higher premiums or out-of-pocket costs. 

Plan benefits are another critical factor. Look at whether the plan offers supplemental benefits, such as vision or dental coverage. If you take several prescription medications, see if the plan provides prescription drug coverage and what medications are listed in its formulary and covered by the insurer. If your medications aren't covered, shop around for another plan that better meets your needs.

Whether you've just become eligible for Medicare or are switching plans during a special enrollment period, you can use Medicare's Plan Finder tool to find Medicare Advantage plans offered in your area. Start there, but if you have additional questions or are unclear about potential costs or what is covered and what isn't, don't hesitate to call the insurer, talk to a representative and get clarification before you make a final decision.
