Medicare is health insurance for people 65 or older. You may be eligible to get Medicare earlier if you have a disability, End-Stage Renal Disease (ESRD), or ALS (also called Lou Gehrig’s disease). Some people get Medicare automatically, others have to actively sign up -- it depends if you start getting retirement or disability benefits from Social Security before you turn 65.

 Medicare Advantage (MAPD) plans combine hospital, medical, and prescription drug coverage in one policy, often including extra benefits like dental or vision. 

Medicare Supplements (Medigap) help pay out-of-pocket costs not covered by Original Medicare. 

Prescription Drug Plans (PDP) assist with medication expenses. Having proper Medicare coverage protects your health and prevents unexpected financial burdens.
