There are four basic parts of Medicare: A, B, C and D. Each part helps pay for certain health care services. Each part also has certain costs that you may have to pay. Your Medicare costs will depend on what coverage you choose and on what health care services you use.
Most people get premium-free Part A.
You can get premium-free Part A at 65 if:
You already get retirement benefits from Social Security or the Railroad Retirement Board. You're eligible to get Social Security or Railroad benefits but haven't filed for them yet. You or your spouse had Medicare-covered government employment.
If you're under 65, you can get premium-free Part A if:
You got Social Security or Railroad Retirement Board disability benefits for 24 months.
You have End-Stage Renal Disease (ESRD) and meet certain requirements.
Part A premiums
If you buy Part A, you'll pay up to $422 each month in 2018. If you paid Medicare taxes for less than 30 quarters, the standard Part A premium is $422. If you paid Medicare taxes for 30-39 quarters, the standard Part A premium is $232.
In most cases, if you choose to buy Part A, you must also:

2019 Medicare Changes
The standard Part B premium amount in 2019 will be $135.50 (or higher depending on your income). You'll pay the standard premium amount (or higher) if:

standard premium amount of $135.50.)
Your modified adjusted gross income as reported on your IRS tax return from 2 years ago is
above a certain amount. If so, you'll pay the standard premium amount and an Income Related Monthly Adjustment Amount (IRMAA). IRMAA is an extra charge added to your premium.
Part B premiums
You pay a premium each month for Part B. Your Part B premium will be automatically deducted from your benefit payment if you get benefits from one of these:
Railroad Retirement Board
Office of Personnel Management
If you don’t get these benefit payments, you’ll get a bill.
Most people will pay the standard premium amount. If your modified adjusted gross income is above a certain amount, you may pay an Income Related Monthly Adjustment Amount (IRMAA). Medicare uses the modified adjusted gross income reported on your IRS tax return from 2 years ago. This is the most recent tax return information provided to Social Security by the IRS.
Part B is medical coverage. It covers doctor visits, clinic services and care you receive as an outpatient.
Medicare Part B helps pay for care you receive in a clinic or hospital as an outpatient. Part B also covers most doctor services you receive as a hospital inpatient. Most other hospital services are covered by Part A.
What Does Medicare Part B Cover?
Medicare Part B covers doctor visits and most routine and emergency medical services. It also covers some preventive care, like flu shots. The list below shows more examples of what Part B covers.
What Does Medicare Part B Cost?
Some people automatically get Medicare Part B (Medical Insurance), and some people need to sign up for Part B. Learn how and when you can sign up for Part B.

If your yearly income in 2017 (for what you pay in 2019) was
Medicare Part C
What Does Medicare Part C Cost?
Each Medicare Advantage (Part C) plan sets its own specific costs, but the types of costs they include are similar.
Your out-of-pocket costs in a Medicare Advantage Plan (Part C) depend on:
Whether the plan charges a monthly premium . Some plans have no premium.
Whether the plan pays any of your monthly Medicare Part B (Medical Insurance) premium.
Some plans pay all or part of your Part B premium.
Whether the plan has a yearly deductible or any additional deductibles.
How much you pay for each visit or service ( copayment or coinsurance ). For example, the plan
may charge a copayment, like $10 or $20 every time you see a doctor. These amounts can be
different than those under Original Medicare .
The type of health care services you need and how often you get them.
Whether you go to a doctor or supplier who accepts assignment if:
You're in a PPO, PFFS, or MSA plan.
You go out-of-network .
Whether you follow the plan's rules, like using network providers.
Whether you need extra benefits and if the plan charges for it.
The plan's yearly limit on your out-of-pocket costs for all medical services.
Whether you have Medicaid or get help from your state.
How Medicare Advantage Cost Sharing Works
Most Medicare Advantage plans use a combination of deductibles, co-insurance and co-pays to share the cost of the services you use. Cost-sharing usually applies to all of the services the plan covers.
You need to read the details of each individual Medicare Advantage plan to get the full story on its costs. Most plans have network doctors and pharmacies that may offer plan members discounted pricing.
Part C is Medicare Advantage. These plans combine the coverage of Parts A and B into one plan. They often include prescription drug coverage, too.
Medicare Advantage plans are offered by private insurance companies approved by Medicare. You must be enrolled in both Part A and Part B to join a Medicare Advantage plan. You’ll still be in the Medicare program, but you will receive your benefits through the plan instead of through Original Medicare.
What Does Medicare Part C Cover?
Medicare Advantage (Part C) plans combine coverage for hospital care, doctor visits and other medical services all in one plan. Plans are required to provide all of the benefits offered by Medicare Parts A and B (except hospice care, which continues to be provided by Part A). Many plans also provide prescription drug coverage and additional benefits like routine dental and eye care.
Medicare Part D
Part D is prescription drug coverage. Plans cover many medications that are prescribed by your doctor or other qualified health professionals.
Original Medicare (Parts A and B) does not cover prescription drugs. Many people who choose Original Medicare add a prescription drug (Part D) plan or choose a Medicare Advantage plan that includes Part D.
In general, you may enroll in a Part D plan if you are entitled to Medicare Part A or if you are enrolled in Medicare Part B. In addition, you must live in the service area of a Part D plan.
What Does Medicare Part D Cover?
Medicare Part D Plans are required to cover certain common types of drugs, but each plan may choose which specific drugs it covers. The drugs you take may not be covered by every Part D plan. You need to review each plan’s drug list, or formulary, to see if your drugs are covered.
Prescription drug plans do not cover:
Drugs that are not on the plan’s drug list
Drugs that are covered under Part A or Part B
Drugs that are excluded by Medicare
What Does Medicare Part D Cost?
The insurance companies that offer Medicare Part D drug
plans and Medicare Advantage (Part C) plans with drug coverage
set their own prices, but the types of costs they include are similar.
Part D plan premiums and cost sharing can vary widely, even for similar coverage. You need to review plan details carefully.
How Medicare Part D Cost Sharing Works
Medicare Part D has different stages of cost sharing until you reach a set limit on out-of-pocket costs for the year. The limit is $5,100 in 2019. After that, your plan pays most of the cost of your drugs for the rest of the year.
Co-pays, co-insurance amounts and your plan deductible, if any, count as out-of-pocket costs. Premium payments do not.
Part D cost-sharing stages are explained below. The costs shown are for 2019. You may not go through every stage in any given year. If you get Extra Help from Medicare for Part D costs, the coverage gap stage doesn’t apply to you.
