The short answer

Yes, you can switch back to Original Medicare from a Medicare Advantage plan, but timing matters and there are specific enrollment windows when this is allowed.

The full explanation

You are not locked into Medicare Advantage forever. Each year during the Annual Enrollment Period, which runs from October 15 through December 7, you can drop your Medicare Advantage plan and return to Original Medicare, with coverage starting January 1. There is also a Medicare Advantage Open Enrollment Period from January 1 through March 31 each year, which lets you make one switch, including going back to Original Medicare. Outside of those windows, you generally need a Special Enrollment Period triggered by a qualifying life event to make changes. One thing to plan for when switching back is Medigap coverage. Medigap, also called Medicare Supplement insurance, helps cover the out-of-pocket costs that Original Medicare doesn't pay. In most states, if you've been on Medicare Advantage for more than 12 months, insurers are not required to sell you a Medigap plan and can use medical underwriting, meaning they can consider your health history. Utah follows federal baseline rules here, so this is a real consideration. If you're thinking about switching back, talk to an agent before you do it so you understand your Medigap options first.

In 

Utah

 specifically

In Utah, Medigap plans are sold by carriers including SelectHealth, Regence BlueCross, Humana, and others. Since Utah does not have additional state protections beyond the federal guaranteed issue rules, it is especially important to understand your Medigap eligibility before dropping a Medicare Advantage plan.

What this means for you

For you, this means switching back to Original Medicare is possible, but making the move without checking your Medigap options first could leave you with higher out-of-pocket costs and limited ability to get supplemental coverage later.
