There are Medicare changes coming in 2020 that will impact all current and future recipients.
According to Medicare FAQ, starting in 2020 there will be no more first-dollar coverage plans to those who are considered Medicare eligible after 2020.
First-dollar plans leave you with zero out of pocket costs. This includes Plan F, which Forbes Magazine says is the most popular plan. As long as you turned 65 before January 1st 2020, you can continue to enroll in the first-dollar coverage plans.
