Best Medicare Advantage Plans for 2021


When it comes to Medicare, seniors have plenty of different options. One of these options is a Medicare Advantage plan. Medicare Advantage plans are through private insurance companies. Below we’ll discuss the best Medicare Advantage plans & carriers. These carriers are top companies that have proven themselves in the Medicare space time and time again.

Best Medicare Advantage Plans and Carriers for 2021

  1. Aetna
  2. Humana
  3. Cigna

These long-standing companies offer the best Medicare Advantage plans year after year. But, since Medicare isn’t free, it’s a good idea to have other options for coverage. One option is a Medicare Advantage plan. These plans will take the place of Medicare. When you go to the doctor, your Medicare Advantage Plan ID card is your main card for Medicare.

These plans have Part D, which can make keeping track of your healthcare easier. Some plans even include things like routine dental, routine eye care, and silver-sneakers fitness programs. Also, more plans are offering a Part B give-back option where you get a lower Part B premium when you enroll in that policy. But. you’ll still want to check the Part D formulary. Choosing a reliable company to handle your Medicare Advantage benefits is essential.

Some states have more Medicare Advantage plan enrollees than other states. For example, fewer beneficiaries in Louisiana have Medicare Advantage than the percentage of enrollees in Florida.

Things to Know About Medicare Advantage Plans

  • You can only join at certain times during the year unless you qualify for a Special Election Period. In most cases, you enroll in a plan for a year.
  • The Medicare Advantage Open Enrollment Period allows beneficiaries to switch to another plan. They can even return to Medicare and enroll in a Medicare Supplement plan if they’re unhappy with their current Advantage plan.
  • Check with the plan before you get a service to find out if the service is covered and what your costs might be.
  • Many times, Medicare Advantage plans require prior authorization.
  • Following plan guidelines, like getting a referral when needed, can keep your costs lower. Check with your plan.
  • Providers can join and leave a plan’s provider network at any time during the year. Your policy can change the providers in the network at any time. If either of these things happens, you’ll need to choose a new provider.
  • If your plan decides to stop participating in Medicare, join another Health plan or return to Medicare.
  • Once you enroll, you’ll automatically lose any drug plan you had. You can’t have an MA plan and a separate prescription drug plan unless it is a PFFS Medicare Advantage plan.
    • You get prescriptions through most Advantage plans. Individuals with a Medigap or Medicare will need a separate drug policy.

Understanding the Types of Medicare Advantage Plans

There are different types of Medicare Advantage Plans; Health Maintenance Organizations (HMO) plans, Preferred Provider Organization (PPO) plans, Private Fee-for-Service (PFFS) Plans, Special Needs Plans (SNPs), and HMO Point-of-Service (HMO-POS) plans.

  • HMO plans only cover you when you go to doctors, providers, or hospitals in your plan’s network except in urgent or emergencies. Referrals from primary care doctors to see other doctors or specialists may be required.
  • PPO plans will generally cover you outside the network with a higher out of pocket cost to you.
  • PFFS plans are most like Medicare; you can go to any doctor, provider, or hospital if they accept the plan’s payment terms.
  • Special Needs Plans provide specialized health care for specific groups of people, like those with Medicare and Medicaid, people living in a nursing home, or those with certain chronic medical conditions.
  • HMO-POS plans may allow you to get some services out-of-network for a higher cost.

What is the Highest Rated Medicare Advantage Plan

Of course, every person and location will have a different “best” option. But, overall, we love Aetna Medicare Advantage plans for the more extensive doctor networks than some of the other options. But, Humana and UnitedHealthcare are still both companies with high customer satisfaction ratings. Ultimately, the best policy is the one that brings you the most value. For some Medigap vs Medicare Advantage could be better. But, the choice is yours to make. We’re here to help you figure out your options and identify that “best for you” policy.

  1. Spouse turns 65 in end of Aug. does SS automatically enroll him. What’s my next step..need best coverage for a cancer patient.Any suggestions.

    1. Hi Holly! If your spouse is currently collecting Social Security benefits, they will be automatically enrolled into both Part A & Part B. They will receive their Medicare card a few months prior to their birthday. It’s extremely important that you enroll in a Medigap plan within 6 months of their Part B going into effect since they will be in their Medigap Open Enrollment window and pre-existing conditions, such as cancer, won’t impact them getting into a plan. I would go with Part A, Part B, then enroll in Plan G for Medigap & Part D for prescriptions. Give us a call and we can help!

  2. BUT they can probably charge you more or provide less options. I’m SO SCARED to change average programmes!!

  3. I am a retired federal employee and have kept by Federal Employee Benefits Health plan,FEHP, When speaking with the When speaking to the person that makes the appointments she says they only accept medicare advantage programs. I told the person I had FEHB that was secondary to Medicare. Does this sound reasonable , do I need to speak to another person that might know more? Thanks for your help

    1. Hi David! It’s possible that the facility you spoke to only accepts Medicare Advantage plans. These are offered by private carriers, not the federal government. More than likely you have Original Medicare as your primary and your FEHB as your secondary. You can use the Care Compare tool to find doctors near you that accept Medicare.

  4. Do Supplements take payment using part B like Medicare advantage or how does Part B work with supplements and Advantage doent it take your part N?

    1. Hi Judy. Some Medicare Advantage plans are known as “Give Back Plans.” They reduce your Part B premium by giving some of it back to you. They’re able to do this since the carriers get paid by Medicare to take on your risk. The carrier also makes this money back by charging you a higher premium and collecting other out of pocket costs in the form of cost-sharing from each enrollee. You still have to enroll in both Part A and Part B to enroll in either a Medicare Advantage plan or a Medigap plan. Carriers that offer Medigap plans do not get paid by Medicare. They cannot use a portion of the premium you pay for Part B and apply it to your Medigap premium. Medigap plans work with your Part B by filling in the gaps in coverage, such as the 20% coinsurance for all outpatient services. Medicare Advantage plans do not always cover the 20% coinsurance, each carrier determines how much they will pay for each service. They could decide to charge you the 20% coinsunrace, plus a high co-pay. When if you have a Medigap plan, you would not have to pay the 20% coinsurance and there are never any copays.

  5. I have Aetna Elite Advantra PPO Medicare Advantage. I see things are changing in my policy. In the past I have viewed a Medicare Advantage comparison in SHIIP’s website for Iowa. This year the website has changed and I have not been able to find that comparison. Can you help me with the address of this information for 2021.

    1. Hi Cathy! Yes, we can help you with that. We just need some information from you to see what Medicare Advantage plans are available in your zip code. If you fill out our compare rates form, we’ll contact you with the comparison you’re looking for Aetna and all other carriers as well.

  6. If your over 65 and on Medicare but did not take plan d and now looking for an advantage plan I know you will have to pay a penalty because you did not take a prescription plan do you also have to pay for plan d plus the penalty

    1. Hi Jeanne! So, there is a penalty for not signing up for Part D when you’re first eligible. However, it does not impact your enrollment or premiums if you choose to enroll in a Medicare Advantage plan. This penalty only impacts you when you go to enroll in a stand-alone Part D plan. Yes, you’ll have to pay for Part D + the penalty, which is added to your monthly premium for the rest of your life. However, if you had creditable coverage, then the penalty won’t apply to you.

  7. Medicare advantage plans all require prior authorization. Traditional Medicare doesn’t. Medicare advantage plsns limit your doctor choice, Medicare doesn’t. Medicare advantage plans are middle men trying to make profits from taxpayers by killing patients as fast as possible.

  8. Please do NOT be fooled by the advertisement from Medicare advantage plan. All the private Medicare advantage plans will require prior authorization for expensive but necessary treatments. Many time patients are dead by the time they get prior authorization. Medicare advantage plans also limit your choice of doctors. Overall, Medicare advantage plans are thieves stealing tax dollars through killing patients by delaying and denying treatments. Preserve the traditional Medicare!

    1. Hi John! If you want less out of pocket costs, then Medicare Supplements are better. They cover most, if not all, out of pocket costs depending on the letter plan you choose. With Medicare Advantage, you’ll always have out of pocket costs. What you would pay out of pocket with a Medicare Supplement will be less than the Medicare Advantage maximum out of pocket costs.

  9. Are Aetna Medicare Advantage Plans available in all 50 states? Aetna Medicare Essential PPO Plan for 2020 has in-network Aetna Providers and the associated costs, also Out-Of-Network (OON) providers will be covered and my share of the cost is 40%. If I live in Georgia and require medical treatment in another state, then could I go to an in-network Aetna Provider in that state and still have the in-network Aetna Provider associated costs for that service?

    1. Hi Donald! Unfortunately, Medicare Advantage plans are not available in all states. Your plan may or may not cover care outside of its service area. I would contact your plan to see what rules and costs apply when you travel within the U.S.

  10. I’m the widow of a veteran with Tricare for Life coverage. How does this work, both for doctors and prescriptions, with a Medicare Advantage plan?
