Enrolling in Medicare is not required every year. Once you're enrolled in Medicare, your coverage will generally continue automatically each year. However, it's important to review your coverage annually during the Medicare Open Enrollment Period, which typically runs from October 15 to December 7. During this time, you can make changes to your Medicare coverage, such as switching between Original Medicare and Medicare Advantage plans, or changing your prescription drug coverage. It's also an opportunity to review any changes in costs, coverage, and benefits that may affect your current plan. If you're satisfied with your current coverage and don't want to make any changes, you don't need to take any action. It's always a good idea to stay informed about any updates or changes to Medicare, as well as any potential changes to your healthcare needs, to ensure you have the most suitable coverage for your situation. If you have specific questions about your Medicare coverage, it's advisable to consult with a licensed insurance agent or a Medicare specialist for personalized guidance.
