The ending of Cost Plans in most counties means that those who currently have them will need to make some important decisions in the fall during Medicare Open Enrollment. For now, there isn’t much to do. Those with Cost Plans will continue to have coverage through Dec. 31, 2018, and in some counties, Cost Plan coverage will continue in 2019. You can contact your Medicare plan to find out if you have a Cost Plan, so you’ll be ready if you need to make a change in the fall, if need be.
