The costs associated with Medicare depend on the type of coverage you’re using and the services you need.
Part A: You usually won’t pay a monthly premium for Medicare Part A (Hospital Insurance) coverage as long as you or your spouse paid Medicare taxes for a certain amount of time while working. This is sometimes called "premium-free Part A."
Part B: The premiums associated with Medicare Part B will vary based on your income (in 2019, they ranged from $134-$428 per person). There is also a deductible and coinsurance requirement for Part B.
Part C: You usually pay a monthly premium for your Medicare Advantage plan (in addition to your monthly Part B premium), including a copayment or coinsurance for covered services. Many Part C plans offer vision, hearing, and dental coverage, and costs, extra coverage, and rules vary by plan.
Part D: Part D premiums vary based on your income (in 2019 they range from $12.40-$70.90 per person) and the plan you select. There are also related deductibles and coinsurance.
