Does Medicare Pay for Nursing Home Stays: Skilled Nursing Facility (SNF) vs. Long-Term Care

The Bottom Line: When most people ask, «does medicare cover nursing home costs,» they are often thinking of long-term «custodial» care (help with daily living). Medicare does not pay for long-term custodial care. However, Medicare Part A does pay for short-term stays in a Skilled Nursing Facility (SNF) for rehabilitation or medical care—provided you meet the «4 Pillars» of eligibility explained below.

Skilled Nursing Care vs. Custodial Care: What’s the Difference?

Medicare’s coverage hinges first on whether the type of care needed is «skilled nursing» or «custodial,» then on duration.

*Medicare coverage for SNF care is strictly conditional. You must satisfy the four pillars (requirements) in the next section to be eligible.

The 4 Pillars of Skilled Nursing Facility (SNF) Eligibility

Coverage is not automatic. To have Medicare pay for your SNF temporary stay, you must satisfy all four of these requirements:

1. The «3-Day Rule»: You must have a medically necessary 3-consecutive-day inpatient hospital stay. Time in the ER, under observation or the day of discharge does not count, while the admission day does. (Note: Medicare math is tricky here—see the Discharge Day rule).
2. The 30-Day Window: Generally, you must enter a Medicare-certified SNF within 30 days of that hospital discharge.
3. Medical Necessity: A doctor must certify that you need daily skilled care that can only be provided in a skilled nursing facility on an inpatient basis.
4. Available Days: You must have days remaining in your Benefit Period. (This is the «clock» that determines your coverage;see how to calculate yours below).

The «Discharge Day» Rule aka “Counting Midnights”

No matter the reason for the hospital stay, Medicare has specific rules for how the 3-day inpatient stay is counted.It counts inpatient hospital days using a midnight-to-midnight method.

• The Rule: Medicare counts the day you are admitted, but never counts the day you are discharged, time spent in the emergency room or under observation toward your 3-day requirement.
• Example: If you are admitted on Monday and discharged on Wednesday, you only have 2 days of inpatient credit. You would not qualify for SNF coverage. You must stay through at least Thursday (3 midnights) to count.

The Observation Status «Gotcha»

Even if you stay 3 midnights, you may still be denied. If the hospital classifies your stay as «Observation» (outpatient), those days do not count toward your 3-day rule. Advocacy Tip: Ask daily: «Am I admitted as an inpatient, or am I under observation?» If the answer is «Observation,» your subsequent SNF stay may not meet the requirement for Medicare-covered SNF care.

How Much Does Medicare Pay? (2026 Coverage Windows)

Instead of looking at what you owe, it is often clearer to look at what Medicare actually covers. Any amount not listed here must be covered by you, your supplemental insurance (Medigap), Long-Term Care insurance, or Medicaid.

1. The Part A Deductible: The «Gatekeeper»

In 2026, the Medicare Part A deductible is $1,736 per benefit period. If that deductible was already met during the hospital stay, it does not have to be paid again for the covered SNF stay.

• Pro-Tip: If your hospitalization began in 2025 but your SNF stay starts in 2026, you only pay the 2025 deductible ($1,676) since both stays are part of the same benefit period. You do not pay a new deductible just because the calendar year changed.

2. The 100-Day Limit

Once the deductible is met for the benefit period, Medicare Part A pays on a sliding scale:

*Filling the Gaps: Who pays the rest?

If you see a cost in the «What Medicare Does NOT Cover” column above, these are some of the most common ways families may help cover it:

• Long-Term Care (LTC) Insurance: Some policies will pay your $217/day coinsurance and will continue to pay the facility’s daily rate after Day 100. Coverage varies by policy. Check your „Elimination Period“—some policies require you to pay out-of-pocket for a certain number of days before benefits begin.
• Medigap (Medicare Supplement): Many Medigap plans specifically cover the $217/day coinsurance for days 21–100. However, they usually stop paying on Day 101 when Medicare stops.
• Medicaid: If you meet your state’s financial eligibility rules, Medicaid may pay the $217/day coinsurance and continue to pay for „long-term custodial care“ indefinitely after Day 100.
• Private Pay: If you have no other insurance or aid, you will pay these costs from your personal savings or retirement.

What’s Included (and What’s Not) in SNF Coverage?

When you qualify, and once your deductible is met, Medicare-covered SNF care may cover a range of services related to  your medical treatment and recovery.

• Covered: Semi-private room, meals, skilled nursing care (wound care, IV meds), therapy (Physical, Occupational, Speech), medications/supplies used for your treatment, and necessary ambulance transportation when other transportation would endanger your health and the needed service is not available at the SNF.
• NOT Covered: Custodial care (once rehab is done), private rooms (unless medically necessary), private-duty nursing, or personal items like a TV/phone.

How the „Benefit Period“ Clock Works

This is not a calendar year. It is a specific window of time that can reset multiple times a year.

• • Starts: The day you are admitted as an inpatient to a hospital or SNF.
  • Ends: When you have gone 60 days in a row without any inpatient hospital care or skilled nursing care in a SNF.
  • The Reset: Once those 60 days pass, the clock resets. If you go back to the hospital, you must pay a new Part A deductible, but you receive a fresh 100 days of SNF coverage (if you meet the 3-day rule again).

• Deductible: Remember — deductible is tied to Benefit Period, NOT to Calendar year.You may have more than one benefit period in the same year.

• Annual Rates: While the deductible stays tied to the Benefit Period, the daily cost sharing amounts, such as daily coinsurance, changes annually on January.
