Medicare Advantage Plans must cover all of the services that Original Medicare covers. However, if you’re in a Medicare Advantage Plan, Original Medicare will still cover the cost for hospice care, some new Medicare benefits, and some costs for clinical research studies. In all types of Medicare Advantage Plans, you're always covered for emergency and urgently needed care.
The plan can choose not to cover the costs of services that aren't medically necessary under Medicare. If you're not sure whether a service is covered, check with your provider before you get the service.
Most Medicare Advantage Plans 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.
In 2018, the standard Part B premium amount is $134 (or higher depending on your income). However, some people who get Social Security benefits pay less than this amount ($130 on average in 2018).
If you need a service that the plan says isn't medically necessary, you may have to pay all the costs of the service. But, you have the right to appeal the decision.
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.
