What is the Downside to Medicare Supplement Plans?

The biggest downside to Medicare Supplement plans is the upfront costs. In the long run, you will likely spend less on healthcare with Medigap than Medicare Advantage or Original Medicare (Part A and Part B) only. However, Medicare Supplement plans require higher monthly premiums than Medicare Advantage, and you will still need to pay your Original Medicare and Medicare Part D premiums, if applicable.

When you receive healthcare services with Medigap, you will find that your out-of-pocket costs are much lower than any other coverage type. So, to receive great benefits in the long run, you will need to pay a higher monthly premium, which may be a turn-off for some consumers.

Is There a Medicare Supplement Plan That Covers Everything?

When it comes to Medicare Supplement plans, you only receive coverage for services Original Medicare covers. This means that Medicare Supplement plans do not cover services not typically covered by Medicare Part A or Part B.

Some of the essential benefits Original Medicare does not cover include dental, hearing, vision, and prescription drug benefits. To receive this coverage, you must enroll in separate plans that work alongside your Original Medicare and Medicare Supplement policy.

However, if you are looking for the Medicare Supplement plan with the most comprehensive coverage, you will find it in Medicare Supplement Plan F if you are eligible. This plan covers 100% of the out-of-pocket costs Original Medicare leaves. To qualify for this plan, you must enroll in Original Medicare before January 1, 2020.

If you are ineligible for Medicare Supplement Plan F, Plan G is your next best option. Once you pay the annual Medicare Part B deductible, Medicare Supplement Plan G covers 100% of your out-of-pocket costs, just like Medicare Supplement Plan F.

What is the Best Way to Choose a Medicare Supplement Plan?

The best way to choose a Medicare Supplement plan is by comparing all your options and deciding which plan best fits your budget and healthcare needs. To compare all the plans in your area in one place, you will need to work with a licensed brokerage with access to all carriers in your area.

Once you compare all plans, your broker can help you weigh the pros and cons of each carrier until you decide which is suitable for you. Then, choosing a coverage level for your plan is the easy part.

How to Choose the Best Medicare Supplement Company for You

The policy with the lowest premium rate at enrollment is not necessarily the best choice in the long run. Although the monthly premium is crucial when enrolling in a Medicare Supplement policy, it should not be the only factor you consider.

It is crucial to think about your future experience with the company when enrolling. In some cases, you may be stuck in your plan due to health issues that will not allow you to pass underwriting health questions. If this is the case, you want your policy to stand the test of time.

Overall, you will benefit from selecting a policy from an established company. The insurance company you choose is just as vital as the standardized Medigap plan in which you enroll.
