A Medicare Advantage Plan (like an HMO or PPO) is another way to get your Medicare coverage. If you join a Medicare Advantage Plan, you still have Medicare. You'll get your Medicare Part A (Hospital Insurance) and Medicare Part B (Medical Insurance) coverage from the Medicare Advantage Plan, not Original Medicare. Medicare Advantage Plans, sometimes called "Part C" or ''MA Plans," are offered by private companies approved by Medicare.
In all types of Medicare Advantage Plans, you're always covered for emergency and urgent care. Medicare Advantage Plans must cover all of the services that Original Medicare covers except hospice care and some care in qualifying clinical research studies. Original Medicare covers hospice care and some costs for clinical research studies even if you're in a Medicare Advantage Plan. Medicare Advantage Plans may offer extra coverage, like vision, hearing, dental, and health and wellness programs. Most include Medicare prescription drug coverage (Part D). In addition to your Part B premium, you may pay a monthly premium for the Medicare Advantage Plan.
Medicare pays a fixed amount for your care each month to the companies offering Medicare Advantage Plans. These companies must follow rules set by Medicare. However, each Medicare Advantage Plan can charge different out-of-pocket costs and have different rules for how you get services (like whether you need a referral to see a specialist or if you have to go to doctors, facilities, or suppliers that belong to the plan for non-emergency or non-urgent care). These rules can change each year. The plan must notify you about any changes before the start of the next enrollment year.
