Medicare Advantage Plans must cover all of the services that Original Medicare covers except hospice care. Original Medicare covers hospice care even if you're in a Medicare Advantage Plan. In all types of Medicare Advantage Plans, you're always covered for emergency and urgently needed care.

Medicare Advantage Plans may offer extra coverage, like vision, hearing, dental, and/or health and wellness programs. Most include Medicare prescription drug coverage (Part D). In addition to your Part B premium, you usually pay a monthly premium for the Medicare Advantage Plan.

You can also ask the plan for a written advance coverage decision to make sure a service is medically necessary and will be covered. If the plan won't pay for a service you think you need, you'll have to pay all of the costs if you didn't ask for an advance coverage decision.
