See whether you would prefer a Medicare Advantage plan. Medicare Advantage plans have to offer at least the basic benefits that Original Medicare offers, but some Medicare Advantage plans might also offer coverage for things that Original Medicare doesn’t cover. Use the Medicare Plan Finder to see if there’s a Medicare Advantage plan that meets your needs.
You’re eligible for Medicare if you’re age 65 or older, receiving disability benefits, or have certain conditions, like end-stage renal disease or amyotrophic lateral sclerosis (Lou Gehrig’s disease). You must be either a United States citizen or a legal permanent resident of at least five years. In some instances, you may not have to take any action in order to enroll. This may happen if you’re turning 65 and already receive Social Security benefits or Railroad Retirement Board benefits.
Medicare Part D is optional prescription drug coverage. If you have Original Medicare, you can get this coverage through a Medicare Prescription Drug Plan, offered through private Medicare-approved insurance companies. These plans offer stand-alone prescription drug coverage that work alongside Original Medicare, Part A and Part B. A Medicare Advantage Prescription Drug plan also provides the Medicare Part D benefit, covering all Medicare benefits under a single plan.
