A: For 2018 coverage, open enrollment for Medicare Advantage and Medicare Part D ran from October 15, 2017 to December 7, 2017.

For people who are on Medicare Advantage, the annual Medicare Advantage Disenrollment Period ran from January 1 to February 14, 2018.

5-Star Plans

But if there’s a Medicare Advantage or Medicare Part D plan in your area that has earned the government’s five-star (excellent) rating, you’re allowed to switch onto that plan anytime between December 8 and November 30. This is called the 5-star special enrollment period, and you’re allowed to utilize it one time during that period.

For 2018, there are a total of 23 plans that have a five-star rating (unchanged from 2017 but up from 17 in 2016) that have a five-star rating. This includes Medicare Advantage plans as well as Part D prescription drug plans.

General Medicare enrollment for those who didn’t sign up when first eligible

From January 1 to March 31 each year, people who are eligible for Medicare Parts A and B but not yet enrolled can sign up for coverage. It will take effect on July 1 of that year. If you didn’t sign up for Part B when you were first eligible and you haven’t had creditable coverage from an employer plan in the meantime, you’ll have to pay an additional premium for your Part B plan, as a late enrollment penalty.

Special Needs Plans

If you develop a condition that makes you eligible for a Medicare Special Needs Plan (SNP) and an applicable SNP is available in your area, you can join it at any time, but once you join, your special enrollment period ends.

Dual-eligible enrollees

If you’re covered by both Medicare and Medicaid, you can switch plans at any time during the year. This applies to Medicare Advantage as well as Medicare Part D.

Note that there are SNPs designed for people who are dual-eligible for Medicaid and Medicare, and there are also SNPs for people who are institutionalized.

Medigap

You can apply for a Medicare Supplemental Insurance (Medigap) plan at any time during the year. If you’re within the six-month open enrollment window that begins when you turn 65, the coverage is guaranteed issue. That is also the case if you’re in a special enrollment period triggered by a qualifying event. (Be aware that not all of the special enrollment periods for Medicare Advantage or Medicare Part D apply to Medigap plans).

But you can still apply for a Medigap plan outside of open/special enrollment periods — just be aware that in most states, the carrier will use medical underwriting to determine whether to accept your application, and how much to charge you.
