Medicare Costs in 2024: A Complete Breakdown of Premiums, Deductibles, and Out of Pocket Expenses

One of the biggest misconceptions about Medicare is that it provides free healthcare for seniors. While Part A hospital coverage is premium free for most people who paid Medicare taxes during their working years, nearly every other aspect of Medicare involves costs that many beneficiaries do not anticipate. Between Part B premiums, Part D premiums, deductibles, coinsurance, and the costs of services that Medicare does not cover at all, the average Medicare beneficiary spends over $6,000 per year on healthcare out of pocket. For beneficiaries with chronic conditions or those who need frequent specialist visits, the annual cost can be significantly higher. Understanding these costs before you enroll allows you to budget accurately and make informed decisions about supplemental coverage.

Most people do not pay a monthly premium for Part A because they or their spouse paid Medicare taxes for at least 40 quarters during their working years. If you did not meet this threshold, the Part A premium in 2024 is up to $505 per month, which is a significant expense. Even without a monthly premium, Part A has substantial cost sharing requirements. The Part A deductible is $1,632 per benefit period in 2024. A benefit period starts when you are admitted to a hospital and ends when you have been out of the hospital for 60 consecutive days. If you are admitted, discharged, and readmitted within 60 days, it counts as the same benefit period and you do not pay the deductible again. But if 60 days pass between hospitalizations, a new benefit period begins and you owe another $1,632 deductible.

After your deductible, Part A covers the first 60 days of a hospital stay at no additional cost to you. Days 61 through 90 require a coinsurance payment of $408 per day. Beyond 90 days, you begin using lifetime reserve days, which come with a coinsurance of $816 per day, and you only have 60 lifetime reserve days total across your entire lifetime. Once those are exhausted, you are responsible for 100 percent of the cost. Skilled nursing facility care has its own cost structure: Part A covers the first 20 days in full, days 21 through 100 require a $204 daily coinsurance, and after day 100, you pay the full cost. These numbers illustrate why supplemental insurance, either a Medigap plan or Medicare Advantage, is so important for protecting yourself against high hospital costs.

Part B covers doctor visits, outpatient care, medical equipment, preventive services, and some home health services. The standard Part B premium in 2024 is $174.70 per month, which is deducted from your Social Security check. If your income exceeds certain thresholds, you pay a higher premium due to the Income Related Monthly Adjustment Amount. For individuals with income above $103,000 or couples above $206,000, the surcharge ranges from an additional $69.90 to $419.30 per month depending on the income bracket. This surcharge catches many retirees by surprise, particularly those who had a high income year due to selling property, converting a retirement account, or receiving a one time windfall.

The Part B annual deductible is $240 in 2024. After you meet the deductible, Part B generally covers 80 percent of the Medicare approved amount for covered services, and you are responsible for the remaining 20 percent as coinsurance. There is no out of pocket maximum on Part B, which means your 20 percent coinsurance can theoretically grow without limit. A $100,000 cancer treatment would leave you with a $20,000 coinsurance bill under Original Medicare with no cap. This is the most compelling reason to consider either a Medigap supplement plan, which covers most or all of the 20 percent coinsurance, or a Medicare Advantage plan, which is required to have an annual out of pocket maximum.

Part D prescription drug coverage is provided through private insurance companies that offer plans approved by Medicare. Monthly premiums vary by plan and location but average around $33 per month in 2024. Like Part B, higher income beneficiaries pay an additional surcharge on their Part D premium. The standard Part D benefit has a deductible of up to $545, after which you pay copayments or coinsurance based on your plan's formulary. Each drug is placed on a tier, with generic drugs on the lowest cost tiers and specialty medications on the highest.

The most significant recent change to Part D is the annual out of pocket cap that took effect in 2025 under the Inflation Reduction Act. Previously, beneficiaries with expensive medications faced potentially unlimited out of pocket drug costs through the coverage gap, also known as the donut hole. The new $2,000 annual cap means that once you have spent $2,000 on covered drugs in a calendar year, you pay nothing for the rest of the year. This is a major financial protection for beneficiaries who take expensive specialty medications that previously pushed their annual drug costs into thousands or even tens of thousands of dollars. When choosing a Part D plan, compare each plan's formulary against your specific medications because the same drug can have dramatically different copayments under different plans.

Several programs exist to help reduce Medicare costs for beneficiaries with limited income and resources. Medicare Savings Programs pay some or all of your Part B premium, and in some cases your Part A premium, deductibles, and coinsurance. Eligibility is based on income and assets, and the thresholds are higher than many people expect. The Qualifying Individual program, for example, pays your Part B premium if your income is below 135 percent of the federal poverty level. Extra Help, also called the Low Income Subsidy, reduces Part D prescription drug costs for beneficiaries who qualify based on income and resource limits.

Beyond assistance programs, there are practical strategies to keep costs down. Shopping for Part D plans annually during open enrollment ensures you are on the most cost effective plan for your current medications, since plan formularies and pricing change every year. Choosing generic medications when available can cut drug costs by 80 to 90 percent compared to brand name versions. If you are healthy and willing to accept some financial risk, a high deductible Medigap Plan G can provide comprehensive supplemental coverage at a significantly lower premium than the standard version. Working with a licensed Medicare counselor, available free through your State Health Insurance Assistance Program, can help you identify the combination of coverage options that minimizes your total healthcare spending.
