Understanding Medicare Costs: Premiums, Deductibles, and Out-of-Pocket Maximums

What Does Medicare Actually Cost?

Quick Answer: Medicare costs include monthly premiums for Parts B and D (and sometimes Part A), annual deductibles, copayments for services, and coinsurance percentages. In 2025, the standard Part B premium is $185 per month with a $257 annual deductible. Part A has a $1,676 per-benefit-period deductible. Your total out-of-pocket costs depend on which type of coverage you choose: Original Medicare alone, Original Medicare with a Medigap supplement, or a Medicare Advantage plan.

One of the most common questions we hear at Integrity Health Solutions is simply: "How much will Medicare cost me?" The answer depends on several factors, including your income, the type of coverage you select, the medications you take, and how often you see doctors. This guide breaks down every component of Medicare costs so you can plan your healthcare budget with confidence.

Medicare Part A Costs: Hospital Insurance

Medicare Part A covers inpatient hospital stays, skilled nursing facility care, hospice, and some home health services. Most people do not pay a monthly premium for Part A because they or their spouse paid Medicare taxes for at least 40 quarters (10 years) during their working career.

Part A Premium

If you do not qualify for premium-free Part A, the 2025 monthly premium is up to $518 per month (if you worked fewer than 30 quarters) or $285 per month (if you worked 30 to 39 quarters). This is relatively uncommon, but it is important to verify your eligibility when you turn 65 and enroll in Medicare.

Part A Deductible and Coinsurance

The Part A deductible is $1,676 per benefit period in 2025. Unlike most health insurance deductibles that reset annually, the Part A deductible resets each benefit period. A benefit period starts when you are admitted to a hospital and ends 60 days after you are discharged from all inpatient care. If you are readmitted after 60 days, you pay the deductible again.

After the deductible, Part A coinsurance works as follows:

• Days 1 through 60: $0 coinsurance per day after the deductible
• Days 61 through 90: $419 coinsurance per day
• Days 91 through 150 (lifetime reserve days): $838 coinsurance per day
• Beyond 150 days: You pay all costs

For skilled nursing facility stays, you pay $0 for days 1 through 20, then $209.50 per day for days 21 through 100. After day 100, Medicare does not cover skilled nursing.

Medicare Part B Costs: Medical Insurance

Part B covers doctor visits, outpatient care, preventive services, durable medical equipment, and many other medical services. Unlike Part A, everyone pays a monthly premium for Part B.

Part B Premium and IRMAA

The standard Part B premium in 2025 is $185 per month. However, higher-income beneficiaries pay more through the Income-Related Monthly Adjustment Amount, commonly known as IRMAA. The Social Security Administration determines your IRMAA based on your modified adjusted gross income from two years prior (your 2023 tax return for 2025 premiums).

IRMAA surcharges can significantly increase your Part B premium. For example, an individual with income between $106,000 and $133,000 pays an additional $74 per month on top of the standard premium. At the highest income bracket (above $500,000), the total Part B premium exceeds $594 per month. If you have experienced a life-changing event such as retirement, divorce, or the death of a spouse, you can file an appeal with Social Security to use a more recent tax year.

Part B Deductible and Coinsurance

The annual Part B deductible for 2025 is $257. After meeting the deductible, you typically pay 20% coinsurance for most Part B services. This 20% has no cap under Original Medicare, which means a major surgery or extended treatment could result in thousands of dollars in out-of-pocket costs. This is one of the primary reasons many beneficiaries add a Medicare Supplement (Medigap) plan to their coverage.

Medicare Part D Costs: Prescription Drug Coverage

Part D covers prescription medications and is offered through private insurance companies. Each plan has its own premium, formulary (list of covered drugs), and pharmacy network. For a detailed guide on selecting the right plan, see our article on Medicare Part D prescription coverage.

Part D Premiums and Deductible

Part D premiums vary widely by plan. In Florida, monthly premiums range from as low as $0 (when bundled with certain Medicare Advantage plans) to over $100 for standalone plans with broad formularies. The national average is approximately $55 per month. The maximum Part D deductible for 2025 is $590, though many plans have lower or no deductibles.

The Coverage Gap and Catastrophic Coverage

Part D plans have a coverage gap, sometimes called the "donut hole." In 2025, after you and your plan have spent $5,630 on covered drugs, you enter the coverage gap. Thanks to recent legislation, beneficiaries now pay significantly reduced costs during this phase. Once your total out-of-pocket drug spending reaches $2,000 for the year, you enter the catastrophic coverage phase where you pay $0 for covered drugs for the rest of the year.

Part D IRMAA

Just like Part B, Part D has an income-related surcharge. Higher-income beneficiaries pay an additional $13.70 to $81 per month on top of their plan premium, based on the same income brackets used for Part B IRMAA.

Medicare Supplement (Medigap) Costs

Medigap plans are sold by private insurance companies and help pay for costs that Original Medicare does not cover, such as the Part A deductible, Part B coinsurance, and excess charges. Medigap premiums vary based on the plan letter, your age, your location, and the insurance company.

In the Tampa Bay area, popular Medigap plans like Plan G typically range from $120 to $250 per month depending on the carrier and your age. Florida uses attained-age rating for most Medigap plans, which means your premium increases as you get older. The best time to enroll is during your six-month Medigap Open Enrollment Period, which starts when you are both 65 or older and enrolled in Part B. During this window, insurers cannot deny you coverage or charge more due to pre-existing conditions.

Medicare Advantage Costs

Medicare Advantage plans (Part C) are an alternative to Original Medicare offered by private insurers. Many plans in Florida, particularly in the Tampa Bay region, have $0 monthly premiums beyond your Part B premium. These plans typically include prescription drug coverage and extra benefits like dental, vision, and hearing.

However, Medicare Advantage plans use copayments and coinsurance for services, and they have annual out-of-pocket maximums. In 2025, the maximum allowable out-of-pocket limit for in-network services is $8,850, though many plans set their limits lower. When comparing plans, look at the total estimated annual cost including premiums, deductibles, copays, and drug costs for your specific situation. Our guide to the best Medicare Advantage plans in Florida can help you compare options.

How to Minimize Your Medicare Costs

Reducing your Medicare expenses starts with choosing the right combination of coverage for your health needs and budget. Here are practical strategies:

• Compare plans annually: Plan costs, formularies, and networks change every year. What was the best plan last year may not be the best plan this year. Review your options during the Annual Enrollment Period each fall.
• Check for Extra Help: If your income and resources are limited, you may qualify for Medicare Extra Help (Low-Income Subsidy), which can reduce your Part D costs to nearly $0.
• Use in-network providers: If you have a Medicare Advantage plan, staying in-network can save you hundreds or thousands of dollars per year.
• Review your prescriptions: Ask your doctor about generic alternatives and use the Medicare Plan Finder to identify plans that cover your specific medications at the lowest cost.
• Work with an independent agent: A licensed agent can compare plans across all carriers to find the lowest total cost for your situation. At Integrity Health Solutions, this service is completely free.
