A person can hear that Medicare Part A is “free” and reasonably assume their healthcare costs will be minimal. Then the first hospital bill arrives. Original Medicare is valuable coverage, but it has deductibles, coinsurance, and coverage gaps that deserve careful attention before you enroll. If you are asking how much is Original Medicare Part A and B, the short answer is that Part A is often premium-free, while most people pay a monthly Part B premium. The more useful answer is that your total cost depends on how you use care, your work history, and your income.
For 2026, most beneficiaries pay $202.90 per month for Medicare Part B. Part A is generally $0 per month for people who qualify for premium-free coverage. Those numbers are only the starting point. Understanding what happens when you need hospital care, outpatient treatment, or ongoing physician services is what helps you build a realistic Medicare budget.
How Much Is Original Medicare Part A and B in 2026?
Original Medicare consists of Part A, which primarily covers inpatient hospital care, and Part B, which primarily covers outpatient care and medical services. Both have their own rules for premiums and cost sharing.
Medicare Part A costs
Most people do not pay a monthly Part A premium because they or a spouse paid Medicare taxes for at least 40 quarters, or about 10 years, while working. This is called premium-free Part A. If you have 30 to 39 work quarters, the 2026 Part A premium is $311 per month. If you have fewer than 30 quarters, it is $565 per month.
The bigger consideration for many people is the Part A deductible. In 2026, the inpatient hospital deductible is $1,736 per benefit period. A benefit period begins when you are admitted as an inpatient and ends after you have been out of a hospital or skilled nursing facility for 60 consecutive days.
That is different from an annual deductible. If you have separate hospital stays with enough time between them to begin new benefit periods, you could owe the Part A deductible more than once in the same calendar year.
After the deductible, Part A generally covers the first 60 inpatient hospital days of each benefit period. If your stay lasts longer, your daily share increases:
- Days 61 through 90: $434 per day
- Lifetime reserve days: $868 per day
- Skilled nursing facility care, days 21 through 100: $217 per day
- After the available covered days are used: you generally pay the full cost
These amounts do not mean Medicare pays for every service received during a hospital stay. Physician services, specialists, imaging, and many outpatient services can fall under Part B instead.
Medicare Part B costs
The standard 2026 Part B premium is $202.90 per month, usually deducted from your Social Security benefit. If you do not yet receive Social Security, Medicare typically bills you directly.
Part B also has a $283 annual deductible in 2026. Once you meet that deductible, you usually pay 20% of the Medicare-approved amount for covered services. This commonly includes doctor visits, outpatient surgery, lab work, diagnostic tests, durable medical equipment, preventive services, and many cancer treatments administered in an outpatient setting.
The word “usually” matters. The 20% amount is not a flat copay. If a covered outpatient procedure costs more, your share can be more. A series of specialist visits, physical therapy appointments, or infusion treatments can create meaningful out-of-pocket exposure even when Medicare is paying its share.
Why Your Part B Premium May Be Higher
Not everyone pays the standard Part B premium. Medicare uses an Income-Related Monthly Adjustment Amount, commonly called IRMAA, for beneficiaries with higher incomes. For 2026, this determination is generally based on the income shown on your 2024 federal tax return.
If your income exceeds the applicable threshold, you pay the standard Part B premium plus an additional monthly amount. The highest-income beneficiaries can pay substantially more than the standard premium. IRMAA can also increase what you pay for Medicare Part D prescription drug coverage.
This can be a surprise for people retiring at age 65 because the tax return Medicare reviews may reflect their peak earning years, not their current retirement income. A major life-changing event, such as retirement, marriage, divorce, death of a spouse, or loss of income-producing property, may allow you to request a reconsideration. It is worth addressing promptly rather than assuming the higher premium is permanent.
What Original Medicare Does Not Fully Cover
Part A and Part B cover a broad range of medically necessary hospital and outpatient services, but Original Medicare is not an all-inclusive plan. It generally does not cover routine dental care, most routine vision care, hearing aids, long-term custodial care, or most healthcare received outside the United States.
Original Medicare also does not include outpatient prescription drug coverage. You need a separate Medicare Part D plan if you want prescription coverage through Original Medicare. Delaying Part D without other creditable drug coverage can lead to a late enrollment penalty that may continue for as long as you have Part D.
Another critical issue is that Original Medicare has no annual out-of-pocket maximum. There is no built-in ceiling on the 20% Part B coinsurance you may pay for covered outpatient services. For someone with limited healthcare needs, this may not create much concern in a typical year. For someone managing a chronic condition or facing an unexpected diagnosis, the financial exposure can be much greater.
The Cost of Original Medicare Is More Than the Premium
A realistic monthly Medicare budget should account for more than the Part B premium. For someone eligible for premium-free Part A, the basic starting point may include the $202.90 monthly Part B premium, a Part D prescription drug plan premium, and the possibility of deductibles and coinsurance when care is needed.
Some people choose to add a Medicare Supplement insurance plan, also called Medigap, to help pay Original Medicare deductibles and coinsurance. This typically means paying an additional monthly premium in exchange for more predictable out-of-pocket costs and the ability to use any provider nationwide that accepts Medicare.
Others choose a Medicare Advantage plan, which replaces the way they receive Part A and Part B benefits through a private insurer. Medicare Advantage plans often have lower monthly premiums and include an annual out-of-pocket maximum for covered medical services, but they may have provider networks, prior authorization requirements, copays, and plan-specific rules. Neither approach is automatically better. The right choice depends on your doctors, medications, travel habits, budget, and comfort with healthcare costs that may change over time.
Do Not Overlook Enrollment Timing and Penalties
Medicare costs can rise if you miss enrollment deadlines. If you do not have qualifying employer coverage when you become eligible, delaying Part B can trigger a late enrollment penalty. That penalty is generally added to your Part B premium and can last for as long as you have Part B.
The same caution applies to Part A for people who must pay a premium and to Part D for people without creditable prescription coverage. Enrollment timing is especially important if you are working past 65, covered under a spouse’s employer plan, or considering COBRA. Coverage that feels similar to employer insurance does not always protect you from Medicare penalties.
Before making an enrollment decision, verify whether your current coverage is considered creditable and whether the employer size affects your Medicare enrollment obligations. A small misunderstanding can have long-term consequences.
Planning for Care, Not Just This Year’s Premium
The question is not only whether you can afford Part B’s monthly premium today. It is whether your Medicare arrangement can support you if your health needs change next year or five years from now. A low premium can be appealing, but a plan with unexpected copays, limited provider access, or inadequate drug coverage may cost more when you need care.
Ohio Medicare Planning helps beneficiaries look beyond the headline premium and compare the real tradeoffs. Before enrolling, gather your current doctors, preferred hospitals, prescription medications, expected travel, and a realistic monthly budget. A careful review now can help protect both your access to care and your retirement income when it matters most.
