Medicare provides health insurance to 69 million Americans. During Medicare open enrollment, which runs from October 15 to December 7 this year, people can enroll in the program or change plans. You can also switch from original Medicare to a Medicare Advantage plan (or vice versa), and weigh your Part D prescription drug plan coverage against other options.
If you choose original Medicare (Part A and Part B), you can also buy a Medicare Supplement Insurance (Medigap) policy from a private insurance company to cover services and out-of-pocket costs not covered by original Medicare.
