I assume you are referring to the annual enrollment that occurs in Oct, Nov and Dec of each year.
Open enrollment is a time when those with Medicare Advantage Plans (MAPD) and Medicare Part D (drug plans) can make a change in their coverage.
There are few restrictions and generally no medical underwriting. If you have ESRD you cannot enroll in a new MAPD plan.
If you have original Medicare and a supplement (Medigap) plan, you can change plans at any time provided you are in good health. Some states allow you to change Medigap plans on your birthday or plan anniversary, but most states allow you to make changes only through medical underwriting.
Your Medicare Supplement open enrollment is actually a one-time 6-month period that starts the first month that you are age 65 (or older) AND enrolled in Medicare Part B. This period gives you guaranteed issue rights to buy any Medicare Supplement policy in your area with no health restrictions.
The Medicare Advantage (Part C) and Medicare Drug Plans (Part D) have an annual open enrollment that starts October 1st each year. With this open enrollment period you can compare plans beginning on October 1st. You can make changes beginning on October 15th and ending on December 7th. The plan changes take effect on January 1st.
