What Are the Different Parts of Medicare?

Original Medicare consists of Parts A and B. These are sponsored by the government.

It is important to understand that Original Medicare (Parts A and B) does not cover all of your medical expenses. Because of this, other Medicare plans exist to help provide additional coverage for those who need it.

Part C, or Medicare Advantage, plans are private health plans. This Medicare insurance plan includes coverage for everything Part A and Part B cover, and sometimes Part D, depending on the plan.

Part D, or Prescription Drug Coverage, plans are also private health plans. They offer coverage for prescription drug costs.

Medicare Supplement (Medigap) plans help pay some costs not covered by Original Medicare Parts A and B. Medigap plans are private health plans as well.

What Does Original Medicare Cost?

Original Medicare helps pay for many healthcare services and expenses but shares the cost of care through deductibles, copayments (copays) and coinsurance. Original Medicare Part A and Part B have their own separate costs associated with each part. Costs vary from person to person.

Your Original Medicare (Parts A and B) costs may include:

  • Deductible - The amount you pay before Original Medicare begins to pay its share of the cost.

  • Copay - A flat dollar amount (for example, $10) you pay each time you receive care.

  • Coinsurance - A percentage (for example, 10%) you pay for your care after you meet your deductible.

  • Premium - A fixed, monthly amount you pay for your Original Medicare plan coverage. Most people will only have a premium for Part B.

Cost Differences Between Original Medicare Parts A and B

Part A

For most people, Part A has no monthly premium.

You pay a deductible and out-of-pocket expenses with Part A, unless you have a separate Medicare Supplement plan.

Part B

Part B usually has a monthly premium.

For most services, you pay a yearly deductible and coinsurance with Part B, unless you have a separate Medicare Supplement plan.
