Will you lose your Medicare and supplemental insurance if you do not enroll in the Medicare Advantage plan?

No, you will not lose your Medicare and supplemental insurance if you do not enroll in a Medicare Advantage plan. You can choose to stay with Original Medicare (Part A and Part B) and maintain your supplemental insurance (Medigap). However, if you opt for a Medicare Advantage plan, you generally cannot have both at the same time. It's important to review your options and coverage to ensure you make the best choice for your healthcare needs.
