Because there are 4 parts to Medicare, there can be different cost structures. Most people won’t have to pay for Medicare Part A (hospitalization). Eligibility for premium-free Part A is based on your work history during which you paid Medicare taxes. Many people do pay a monthly premium for Medicare Part B, however, which covers outpatient medical services, like doctor visits. Deductibles also apply to services covered under Medicare Parts A and B, so you’ll pay a part of the annual cost.
Medicare Parts C and D are optional coverages and have premium costs of their own. Medicare Part C refers to Medicare Advantage Plans that offer additional coverage in exchange for a monthly premium. Part D, the prescription plan, reduces the cost of medications but also requires a monthly premium. Subsidies may be available for low income households to help reduce overall Medicare costs.
