The annual open enrollment for Medicare has begun and will end on Dec. 7th. During this time anyone who is on Medicare or is Medicare eligible can enroll in a Medicare Insurance plan or change their current plan with no medical questions asked. This includes HMO & PPO Advantage plans, prescription drug plans, and Medicare supplements. Even if you are currently on a plan it makes sense to shop it because new plans come out each year with new benefits that might better suit your needs
