Q&A: Be aware of these issues when switching between Medicare Advantage and Medicare

Dear Liz: I am planning to retire this year. If I choose a Medicare Advantage Plan, am I able to switch back to original Medicare without paying a fine?

Answer: Medicare won’t charge you extra, but you won’t necessarily have “guaranteed issue” rights for a Medigap supplemental policy. If you want to switch after the first 12 months, you could pay a lot more for this important supplemental coverage.

To recap, Medicare Advantage plans are the all-in-one alternative to original Medicare.

Medicare Advantage plans may offer types of coverage that original Medicare does not, such as hearing, dental or eye care. Many people like the fact that their Advantage plans seem to include more than original Medicare, and do so for a low or even no additional monthly premium.

But Medicare Advantage plans are offered by private insurers, which typically have networks of medical providers. These networks, as well as other benefits, can change from year to year. If you get care outside the networks, you typically pay more — sometimes a lot more. The rap on Medicare Advantage plans is that they can be great when you’re healthy, but depending on the plan may not be so great if you get sick.

With original Medicare, benefits remain the same and you can use any provider that accepts Medicare (the vast majority do). But original Medicare coverage has significant gaps, which is why you’ll need a Medigap plan offered by a private insurer.

If you opt for original Medicare when you are first eligible, insurers are required to issue you a Medigap policy and can’t charge you more based on your health status. Without guaranteed issue, an insurer can refuse to write you a Medigap policy or charge you a lot more.

You also have guaranteed issue rights if you buy a Medicare Advantage plan when you first become eligible for Medicare, but decide within 12 months to switch to original Medicare.
