Medicare Advantage Companies

Medicare Advantage plans are sold by private insurance companies. They cover everything Original Medicare does, but often offer additional benefits. Shopping around to find the right company for you can get you the coverage you need at a more affordable price.

Selecting the Right Medicare Advantage Company

Choosing the best Medicare Advantage company for you means comparing plans and researching the companies offering them. Make sure the plans you are considering offer the coverage you want at a price you can afford as you narrow down your choices.

How to Select the Best Medicare Advantage Company for You
Health Care Needs
Medicare Advantage plans bundle several different benefits, including Part D prescription drug coverage, extra benefits and lower out-of-pocket costs. You may want to compare the costs and benefits to Original Medicare and your ability to add Part D drug coverage and Medicare supplemental insurance (Medigap).
While you can find Medicare Advantage plans with $0 monthly premiums, and the average monthly premium for plans is $23, remember that you will still have to pay the Medicare Part B premium.
Extra Benefits
If you would likely use vision, hearing and dental coverage, Medicare Advantage plans may be a better choice than Original Medicare for you. Calculate how much you’d pay out-of-pocket for these services and compare how much you’d save with an advantage plan.
Your Overall Health
If you have a serious or chronic disease, Medicare Advantage plans may be a better choice than Original Medicare with Medigap to limit your maximum out-of-pocket costs. Compare these limits between Medicare Advantage plans you’re considering.
Comparing Medicare Advantage versus Medicare Supplement plans, Medigap will usually have higher premiums but Medicare Advantage plans typically have more out-of-pocket costs.
Be sure to research the background and financial information of the company that is selling a Medicare Advantage plan. And know that similar plans may be more affordable.
