Medicare Advantage penetration continued to grow following the 2020 Medicare Annual Election Period, reaching 36.0% in 2020, according to CMS’s March data release. Thirteen states and territories have MA penetration rates of greater than 40%, with the Commonwealth of Puerto Rico leading the pack at a whopping 69.1% penetration. Just two states, Alaska and Wyoming, have a penetration rate of under 10%. See a complete map of MA penetration, with current MA enrollment by state, below.
