Find affordable Medicare plans

Get Started

As a Medicare beneficiary, it’s important for you to be aware of the costs and expenses associated with the government-sponsored health insurance program. Here’s a look at Medicare premiums, deductibles, and other costs for 2018, for all parts of Medicare, including Original Medicare (Part A and Part B), Medicare Advantage, Medicare Part D, and Medicare Supplement Insurance.

Medicare Part A costs in 2018

Medicare Part A (hospital insurance) is part of Original Medicare. Most Medicare beneficiaries don’t pay a Part A premium — you don’t have to pay this premium if you’ve worked at least 10 years (40 quarters) while paying Medicare taxes. If you do pay a premium for Medicare Part A, you may have to pay a higher premium if you delay enrollment until after you’re first eligible for the program.

Here’s a look at Medicare Part A costs for 2018:

Medicare Part A premium If you don’t qualify for premium-free Medicare Part A, it will cost you $232 per month if you’ve worked and paid Social Security taxes for 30 to 39 quarters, and $422 per month if you’ve worked and paid Social Security taxes for less than 30 quarters.
Medicare Part A hospital inpatient deductible You pay:

  • A $1,340 deductible for each benefit period
  • A $0 coinsurance for each benefit period for days 1-60
  • A $335 coinsurance per day of each benefit period for days 61-90
  • A $670 coinsurance per “lifetime reserve day” for each benefit period for days 91 and over. (You get up to 60 lifetime reserve days over your lifetime; they only apply to hospital stays over 90 days.)

After you’ve used up your lifetime reserve days, you pay all costs, unless you have other coverage.

Skilled Nursing Facility Stay You pay:

  • $0 for the first 20 days of each benefit period
  • $167.50 per day for days 21-100 of each benefit period
  • All costs for each day after day 100 of the benefit period


Medicare Part B costs in 2018

Medicare Part B (medical insurance) is also part of Original Medicare. Part B carries a monthly premium and an annual deductible. Costs shown below are for 2018.

Medicare Part B premium The amount you pay for your Part B premium may vary based on your situation. On average, many beneficiaries pay $130 per month if they pay their Part B premium through their Social Security benefit, which is less than the standard Part B premium amount described below.

If you fall into one of the following categories below, you’ll typically pay the standard premium amount of $134 in 2018 per month:

  • You enroll in Medicare Part B for the first time in 2018.
  • You’re dual-eligible: that is, you get Medicaid assistance in addition to being enrolled in Medicare. Your state pays your Medicare Part B premium through Medicaid.
  • You don’t receive Social Security or Railroad Retirement Board benefits.
  • Your income is over a certain amount; see the table below.
  • You get billed directly for your Part B premium.
Medicare Part B deductible $183 per year

$134.00 $85,000 or less
$428.60 Over $85,000

Besides the premium and deductible, there are other Medicare Part B costs you should know about: for example, many Medicare services and supplies require a 20% coinsurance payment or a copayment after you’ve reached your annual deductible.

Medicare Advantage costs in 2018

Medicare Advantage (Medicare Part C) is private health insurance through which you can get your Medicare Part A and Part B benefits. Medicare Part A continues to pay for hospice benefits when you have a Medicare Advantage plan. Some Medicare Advantage plans include prescription drug coverage and may include other benefits as well. Premiums and deductibles for Medicare Advantage plans may vary, depending on which plan you choose and the extent of your health coverage.

eHealth analyzed results from over 22,000 consumers who chose Medicare plans using eHealth’s online plan comparison tool, and published a Choice and Impact Study in 2015 that found:

  • First-time enrollees in Medicare Advantage Prescription Drug plans may have saved as much as $1,212 in one year.
  •  Beneficiaries who switched from one Medicare Advantage Prescription Drug plan to another could have saved an average of $682 in one year.

Medicare Part D Prescription Drug Plan costs in 2018

Costs for Medicare Part D Prescription Drug Plans may differ depending on various factors, such as the plan you choose and the medications you use. Deductible amounts are determined by the plan; each plan may have a different deductible amount. Some plans may have a $0 deductible amount, and no plan may have a deductible higher than $405 in 2018.

Be aware that many Medicare Part D Prescription Drug Plans place a limit on how much they will pay for your prescription drugs in one year. For the year 2018, once you and your plan have spent a combined $3,750 on covered prescription drugs, you’ll reach the coverage gap (sometimes also referred to as the “donut hole”). During the coverage gap, you may have to pay up to 35% of your plan’s price for covered brand-name prescription drugs and 44% of the price of generic drugs.

If you don’t sign up for Medicare Part D prescription drug coverage (a stand-alone Medicare Part D Prescription Drug Plan or a Medicare Advantage Prescription Drug plan) when you’re newly eligible for Medicare, you might be subject to a late-enrollment penalty when and if you decide to get this coverage at a later date. You may be able to avoid this penalty if you’re covered by another prescription drug plan that’s “creditable” (expected to pay, on average, at least as much as Medicare Part D typically pays).

If you go without creditable prescription drug coverage for a period of 63 consecutive days or more, you could incur the penalty when you sign up for a Medicare Prescription Drug Plan or Medicare Advantage Prescription Drug plan. You can calculate the late-enrollment penalty by multiplying the number of full months you went without Part D or creditable coverage by 1% of the national base beneficiary premium, which is $35.02 per month in 2018. Then, round the total to the nearest $0.10, and add it to your Medicare Prescription Drug Plan’s monthly premium.

Medicare Supplement plan costs in 2018

If you need help paying for health-care costs that aren’t covered by Original Medicare — like deductibles, coinsurance, and copayments — you may want to consider purchasing a Medicare Supplement Insurance plan (also known as a Medigap plan). Medigap is private insurance, and premiums may vary depending on the area you live in and which plan you choose.

There are 10 standardized Medigap plans in most states, and while plans of the same name have the same coverage, the coverage varies among standardized plans of different names. For example, Medigap Plan K has an out-of-pocket maximum of $5,240, while Plan L carries an out-of-pocket maximum of $2,620 (in 2018). Both plans pay 100% of the cost of Medicare-covered services after you reach your out-of-pocket maximum.
