Key Takeaways
-
Medicare Part A may seem simple at first glance, but it comes with complex cost structures and coverage limits that can impact your out-of-pocket expenses.
-
Understanding the fine print, such as benefit periods, coinsurance timelines, and eligibility nuances, can help you avoid unexpected costs.
What Medicare Part A Covers—and What It Doesn’t
Medicare Part A is primarily hospital insurance. It covers inpatient hospital care, skilled nursing facility care, hospice services, and some home health care. However, coverage is not as all-encompassing as it may initially appear.
Inpatient Hospital Care
You’re covered for:
-
Semi-private room
-
Meals
-
General nursing
-
Drugs as part of your inpatient treatment
-
Other hospital services and supplies
You’re not covered for:
-
Private-duty nursing
-
Personal care items (razors, slippers, etc.)
-
Private room (unless medically necessary)
Skilled Nursing Facility (SNF) Care
Coverage is only available after a qualifying hospital stay of at least three consecutive days (not including discharge day), and only if you need daily skilled care.
Hospice and Home Health Services
Hospice coverage is for terminal illnesses, including support services for pain management and emotional support. Home health care is limited and must be doctor-prescribed, requiring specific criteria to be met.
Benefit Periods Aren’t Annual
One of the most misunderstood aspects of Part A is the concept of the benefit period. Unlike traditional insurance plans that reset annually, Medicare Part A uses benefit periods, which reset based on your discharge from medical care.
A benefit period begins the day you’re admitted as an inpatient and ends when you haven’t received any inpatient hospital care or skilled nursing care for 60 days in a row.
This means you could have multiple benefit periods—and multiple deductibles—in one year.
Deductibles and Coinsurance: How Costs Add Up
The standard Part A deductible in 2025 is $1,676 per benefit period. After that, here’s what you may owe:
-
Days 1–60: $0 coinsurance (after deductible)
-
Days 61–90: $419 per day
-
Days 91–150: $838 per day using 60 lifetime reserve days
-
Beyond 150 days: All costs
Skilled nursing care has its own coinsurance structure:
-
Days 1–20: $0
-
Days 21–100: $209.50 per day
-
After day 100: All costs
These costs can quickly add up, especially if you have multiple hospitalizations in a year.
Lifetime Reserve Days Aren’t Renewable
Medicare gives you 60 lifetime reserve days to use beyond the 90th day of an inpatient hospital stay. These are not annual—they are a one-time allotment.
Once used, they do not renew. If you are hospitalized again and exceed 90 days after using all your reserve days, you will be responsible for 100% of the cost.
This feature often surprises people who assume that coverage continues with a copayment indefinitely.
Qualifying for Part A at No Cost
Most people qualify for premium-free Medicare Part A if they or their spouse worked and paid Medicare taxes for at least 40 quarters (10 years). If you have fewer than 30 quarters, you pay the full premium. Those with 30–39 quarters pay a reduced premium.
It’s essential to know where you fall in this structure before assuming your coverage will be free.
Enrollment Is Automatic for Some, Not All
You are automatically enrolled in Part A at age 65 if you are already receiving Social Security or Railroad Retirement Board benefits. However, if you are not yet receiving these benefits, you must sign up manually.
You can enroll:
-
During your Initial Enrollment Period (IEP): A 7-month window starting three months before the month you turn 65
-
During the General Enrollment Period (GEP): January 1 to March 31 annually if you missed your IEP
-
During a Special Enrollment Period (SEP): If certain life events apply, like losing employer coverage
Hospital Status Matters: Inpatient vs. Observation
Medicare Part A only covers inpatient hospital stays. If you are under observation—even if you stay overnight—you may not be considered an inpatient.
This classification matters because:
-
Observation status is covered under Part B, not Part A
-
You may be responsible for higher out-of-pocket costs
-
Observation days don’t count toward the three-day rule for SNF coverage
Always ask the hospital about your status and how it affects your Medicare benefits.
Medicare and Hospital Readmissions
If you are readmitted to the hospital within 60 days of discharge, you are in the same benefit period and won’t owe a new deductible. However, if the readmission happens after 60 days, a new benefit period starts—and so does a new deductible.
Understanding this can help you prepare financially and avoid surprises.
Limited Home Health Benefits
Home health services under Part A are limited to medically necessary care, often following a hospital or SNF stay. You must be homebound, and a doctor must certify the need.
Services may include:
-
Intermittent skilled nursing care
-
Physical or occupational therapy
-
Speech-language pathology
Personal care services or around-the-clock care are not included under Part A.
Not Everything Is Covered
Some services that people often assume are covered under Medicare Part A are not. These include:
-
Long-term custodial care
-
Most dental care
-
Eye exams for prescription glasses
-
Hearing aids and exams
-
Private-duty nursing
These items must be planned for separately through other forms of coverage or out-of-pocket budgeting.
Understanding the Limits Can Help You Plan
The structure of Medicare Part A is designed to provide foundational hospital coverage, but it leaves several gaps. Knowing the details allows you to make informed decisions about supplemental coverage, budgeting, and care planning.

Planning ahead can ensure you don’t face unexpected bills during a vulnerable time.
Making Sense of Medicare Part A in 2025
Medicare Part A can give you valuable coverage when you need hospitalization, skilled nursing, or hospice services—but it is not all-inclusive. Understanding benefit periods, cost-sharing rules, and what isn’t covered is key to avoiding financial surprises.
