Key Takeaways

• Medicare Part A only covers hospital services up to certain limits, which can leave you with significant out-of-pocket expenses after extended or repeated stays.

• Understanding Part A’s benefit periods, deductible structure, and coinsurance requirements is essential to avoid unexpected medical bills.

Understanding What Medicare Part A Actually Covers

When you first enroll in Medicare, it may feel like you’ve checked off one major item from your retirement to-do list. And while Medicare Part A offers substantial support—especially for hospital-related services—it doesn’t provide blanket coverage.

Medicare Part A is designed to help with inpatient hospital stays, skilled nursing facility care (under specific conditions), hospice care, and limited home health services. But that help has strict boundaries. Knowing these coverage limits now can prevent a financial shock later.

The 2025 Part A Deductible: A Costly First Step

In 2025, the inpatient hospital deductible under Medicare Part A is $1,676 per benefit period. This isn’t an annual deductible—it resets based on your hospital usage.

• A benefit period begins the day you’re admitted as an inpatient.

• It ends after you haven’t received inpatient hospital care (or skilled nursing facility care) for 60 consecutive days.

This means you could face multiple deductibles in a single year if you’re admitted to the hospital more than once, with breaks of 60 days or more in between stays.

Daily Coinsurance Kicks in Sooner Than You Think

After the deductible, Medicare Part A covers up to 60 days of inpatient care with no daily coinsurance. But if your hospital stay extends beyond that:

• Days 61–90: You pay $419 per day.

• Days 91–150: You use up your 60 lifetime reserve days. During this period, you pay $838 per day.

• Beyond 150 days: You’re responsible for 100% of the cost.

These daily coinsurance amounts in 2025 add up quickly. Even a moderately long hospital stay can drain your savings if you’re not prepared.

The Clock Resets…But That’s Not Always a Good Thing

Because the benefit period clock resets after 60 consecutive days without inpatient care, Medicare Part A doesn’t operate on a calendar-year schedule. This can be a hidden pitfall.

If you’re hospitalized in January and again in April, each separated by more than 60 days, you start a new benefit period—which means a new $1,676 deductible applies. You might pay this deductible multiple times in the same year depending on your health circumstances.

Skilled Nursing Facility Coverage Has Strict Rules

Many people assume skilled nursing facility (SNF) care is fully covered by Medicare, but it only kicks in after a qualifying hospital stay of three consecutive days as an inpatient (not under observation status).

Once you qualify:

• Days 1–20: No cost to you.

• Days 21–100: You pay $209.50 per day.

• After day 100: Medicare Part A no longer pays.

Many beneficiaries are surprised by the 100-day cap and the requirement for a three-day qualifying stay. If you’re discharged early or admitted under observation status, you may be responsible for the entire SNF bill.

Hospice and Home Health: Limited but Important Benefits

Hospice care is covered under Part A for people with terminal illness and a life expectancy of six months or less. You pay nothing for hospice itself, but small copayments may apply for prescription drugs or respite care.

Home health care, though covered under Part A in limited cases, typically falls under Part B. Misunderstanding this distinction can lead to coverage confusion and bills you didn’t expect.

You Could Still Face Hospital Costs Even When Covered

Here are some common hospital expenses that Medicare Part A does not cover:

• Private-duty nursing

• Personal care items (like toothpaste or razors)

• A private room (unless medically necessary)

Additionally, if you’re admitted to a hospital as an outpatient or under observation status, Medicare Part A may not cover your stay at all. In these cases, Part B applies—and that comes with its own deductible and 20% coinsurance.

Observation Status Can Derail Your Part A Benefits

Hospitals can admit you “under observation,” which means you’re technically considered an outpatient—even if you’re in a hospital bed overnight. This affects not just Part A coverage for the current stay but also eligibility for skilled nursing facility care later on.

If your hospital stay doesn’t meet the inpatient criteria, you may:

• Be denied skilled nursing facility coverage.

• Have to pay out-of-pocket for many services you assumed were covered.

Ask for written confirmation of your hospital admission status. It’s your right.

Lifetime Reserve Days: Use Them Wisely

Medicare gives you 60 lifetime reserve days for hospital stays that go beyond 90 days. These can only be used once in your lifetime.

Once you’ve used all 60 of them:

• You can’t use them again.

• Any future hospital stays beyond day 90 will not be covered under Part A.

People often unknowingly use these days early on, not realizing that they won’t be replenished.

Coordination With Other Parts of Medicare Matters

Because Medicare Part A only covers a portion of your hospital-related expenses, coordinating with other parts of Medicare is essential:

• Medicare Part B may cover physician services and outpatient procedures.

• Medicare Part D provides drug coverage, which isn’t included in Part A.

Some individuals consider additional protection through supplemental coverage, but these come with their own rules and costs. The key is understanding what Part A leaves uncovered.

The Out-of-Pocket Costs Add Up Fast

Even if you only experience one long hospital stay in a year, your costs could look like this in 2025:

• $1,676 deductible

• 29 days beyond day 60: $419/day × 29 = $12,151

• Total out-of-pocket for that one stay: $13,827, not including physician services or medications

And if you have a second stay in the same year after 60 days? That’s another $1,676 right away.

What You Can Do Now to Be Ready

Planning ahead for potential gaps in your Medicare Part A coverage can save you from financial stress. Here’s how to be proactive:

• Keep a detailed medical calendar to track hospital stays and benefit periods.

• Ask your providers about inpatient vs. outpatient status—this determines Part A coverage.

• Review your Medicare Summary Notice (MSN) for billed services and denied claims.

• Learn the timelines that reset your deductible and coinsurance requirements.

Why Medicare Part A Alone Isn’t a Safety Net

Medicare Part A plays a crucial role, but it was never meant to be your only protection against serious health expenses. It covers a lot—but not everything.

The more you understand what triggers a new deductible, when coinsurance begins, or how lifetime reserve days work, the better prepared you’ll be to protect your budget and access the care you need.
