There are only a few MSAs available as of 2023, but they are available in the majority of the states. You can see if any MSAs are available in your area by reaching out to a health insurance broker who is certified to offer Medicare Advantage plans, or by using Medicare’s plan finder tool.
(If you’re using the Medicare plan finder tool: After entering your zip code, you’ll select Medicare Advantage plans, skip the question about drug costs, and then you’ll get to a screen where there’s a box near the top that says “plan type.” That will have a drop-down menu, and if MSAs are available in your area, they’ll be one of the options in that drop-down menu. If MSA isn’t listed, it means there aren’t any available where you live.)
