Key Takeaways
-
While Medicare Part A is often referred to as “premium-free,” it still comes with considerable out-of-pocket expenses that can disrupt your retirement planning if you’re not prepared.
-
Knowing what Medicare Part A doesn’t cover—and how its cost-sharing works—can help you plan ahead, reduce financial shocks, and choose complementary coverage wisely.
Understanding What “Premium-Free” Really Means
You may have heard that Medicare Part A is “free.” While that may sound reassuring, the term can be misleading. In 2025, most individuals qualify for Part A without paying a monthly premium if they or their spouse worked and paid Medicare taxes for at least 10 years (40 quarters). This is commonly known as “premium-free Part A.”
However, this only refers to the absence of a monthly premium. It does not mean you won’t pay anything else. In fact, using Part A services often comes with significant costs that can impact your financial well-being if you’re not aware of them.
Medicare Part A covers inpatient hospital care, skilled nursing facility care, limited home health services, and hospice care. But even within these categories, benefits are limited in scope and duration. There are also strict eligibility criteria, deductibles, coinsurance, and limits on days of care. More importantly, many common and necessary healthcare services fall entirely outside the scope of Part A.
The 2025 Part A Cost Structure
Even if you qualify for premium-free Part A, using these benefits still involves sharing costs. Here’s what you’ll be responsible for in 2025:
-
Inpatient Hospital Deductible: $1,676 per benefit period
-
Coinsurance for Inpatient Hospital Stays:
-
Days 1–60: $0 after meeting the deductible
-
Days 61–90: $419 per day
-
Days 91 and beyond: $838 per day using lifetime reserve days (you get only 60 of these total over your lifetime)
-
-
Skilled Nursing Facility Care Coinsurance:
-
Days 1–20: $0
-
Days 21–100: $209.50 per day
-
Beyond 100 days: You pay 100% of costs
-
Each benefit period begins on the first day of inpatient care and ends once you haven’t received inpatient care for 60 consecutive days. This means you could pay multiple deductibles in a single year if you’re hospitalized more than once after each benefit period ends.
Additionally, some services provided during hospital stays—such as certain private room charges or non-medical extras—may not be fully covered.
What Part A Does Not Cover
To understand the full picture, it’s just as important to know what Medicare Part A does not include. Here are major healthcare services and needs that are not covered:
Long-Term Custodial Care
If you need help with daily personal tasks like dressing, bathing, eating, or using the restroom, but you don’t require skilled medical care, Medicare Part A won’t help. This kind of assistance is classified as custodial care, and it’s typically needed in nursing homes or assisted living facilities. These long-term arrangements are a major expense for many retirees, and you’ll need alternative coverage or savings to pay for them.
Outpatient Medical Services
Medicare Part A doesn’t cover outpatient services like:
-
Doctor visits
-
Outpatient diagnostic tests (X-rays, MRIs, bloodwork)
-
Outpatient surgeries
-
Preventive care such as screenings and vaccinations
-
Physical therapy and rehabilitation done outside a hospital
These are generally covered under Medicare Part B. If you’re only enrolled in Part A, your coverage is incomplete.
Prescription Medications Outside Hospital Settings
Medicare Part A will only cover medications provided during inpatient stays as part of your treatment. If you need prescriptions for chronic conditions, acute illness, or preventive purposes and are not in a hospital, you’ll need separate drug coverage, typically through Medicare Part D or another source.
Routine Dental, Vision, and Hearing Services
Part A doesn’t cover dental exams, cleanings, fillings, dentures, eyeglasses, eye exams, or hearing aids. These services are common in retirement and often necessary for quality of life, but they are completely excluded from Medicare Part A coverage.
Emergency Room Care Without Admission
If you go to the emergency room but are not admitted as an inpatient, Medicare Part A will not pay for that visit. In these situations, services typically fall under Medicare Part B, but if you’re not enrolled in Part B, you could be left with the entire bill.
International Healthcare Services
With very limited exceptions, Medicare does not cover medical care received outside the United States. That includes hospital stays, emergency care, or routine treatment. This can be especially important to consider if you travel frequently or spend extended time abroad.
When You Could End Up Paying More Than Expected
Even with Medicare Part A, out-of-pocket expenses can accumulate quickly in the following situations:
1. Multiple Hospitalizations
Since the $1,676 deductible applies per benefit period, two unrelated hospitalizations that are more than 60 days apart can trigger two separate deductibles in the same year. This means higher cumulative costs than many people anticipate.
2. Long Inpatient Stays
The coinsurance increases sharply after 60 days. For a stay lasting longer than 90 days, you’ll use up lifetime reserve days, which are limited and non-renewable. Once those are exhausted, you’re responsible for all costs beyond day 90.
3. Extended Skilled Nursing Care
Although Part A helps with skilled nursing care, this benefit ends after 100 days per benefit period. Beyond that, coverage stops completely, and you’re liable for the full cost—which can be several hundred dollars per day.
4. Missed Enrollment Periods
If you delay signing up for Medicare and are not covered by a qualifying group health plan, you may face lifelong late penalties and gaps in your coverage. For Part A, the late penalty increases your premium by 10% for twice the number of years you delayed enrollment.
The Role of Part A in the Medicare Framework
Think of Medicare Part A as a cornerstone of your healthcare foundation. But it’s only part of a larger framework. Here’s how it fits into the broader Medicare picture:
-
Part B: Covers outpatient care, preventive services, and doctor visits.
-
Part D: Provides prescription drug coverage for outpatient medications.
-
Medicare Supplement Insurance (Medigap): Helps pay for deductibles, coinsurance, and other costs that Part A and B don’t cover.
-
Other Coverage Options: Some retirees consider additional health plans to help close coverage gaps.
Without coordination across these different parts, relying on Part A alone could leave you underinsured.
Enrollment Timelines Matter More Than You Think
Understanding when to enroll is just as important as knowing what you’re enrolling in. Missing the appropriate window can result in permanent penalties or delayed coverage:
-
Initial Enrollment Period (IEP): This seven-month window starts three months before the month you turn 65, includes your birthday month, and ends three months after. This is the best time to enroll without penalty.
-
General Enrollment Period (GEP): Runs from January 1 to March 31 each year for those who missed their IEP. Coverage begins July 1, and late penalties may apply.
-
Special Enrollment Period (SEP): Available in specific cases, such as when you have qualifying employer coverage past age 65. The SEP lets you sign up without penalties after that coverage ends.
Failing to understand these timelines can create coverage gaps, and worse, penalties that last for the rest of your life.
Preparing for the Gaps in Advance
Because Medicare Part A does not provide full protection, proactive planning is essential. Here are a few strategies to help:
Consider Complementary Coverage
Explore your eligibility for plans that can fill the gaps, such as:
-
Plans that cover routine dental, vision, and hearing services
-
Plans that offer out-of-pocket spending caps for hospital and nursing care
-
Prescription drug coverage through Medicare Part D
Create a Healthcare Budget
Prepare a personal annual budget that factors in:
-
Deductibles and coinsurance for multiple hospital stays
-
Potential long-term care needs
-
Costs of uncovered services like dental or emergency care
-
Drug costs if you take regular medications
If you’re still working and enrolled in a Health Savings Account (HSA), consider maximizing your contributions before Medicare enrollment. After enrolling, you can no longer contribute, but you can still use the funds to pay for qualified expenses.

Healthcare in retirement is complex. Don’t rely on assumptions. Consult with a professional to review how Part A fits your health profile, income situation, and risk tolerance.
Gaining Clarity on Medicare Part A Starts With the Right Questions
Relying solely on Medicare Part A can leave critical gaps in your healthcare coverage. While it provides vital inpatient hospital coverage and can be premium-free for most people, it has very real limitations, including significant deductibles, coverage caps, and services it doesn’t cover at all.
Understanding these details puts you in a stronger position to build a complete plan that protects both your health and your financial future. It’s about asking the right questions, evaluating your personal needs, and taking deliberate action while you still have options.
