Medicare Part A provides coverage for medically necessary care in a skilled nursing facility (SNF) following a qualifying hospital stay. This benefit covers up to 100 days per benefit period, but understanding the details—including costs, requirements, and limitations—is essential to avoiding unexpected bills that can exceed $16,000.
This guide explains exactly what Medicare covers, what you'll pay, and the requirements you must meet to receive this benefit.
Key Points to Remember
- ⚠️ Medicare does NOT cover long-term or custodial care
- 🏥 You must have a qualifying 3-day hospital stay first
- 🔄 Coverage resets after 60 consecutive days out of a facility
- ✅ The first 20 days are fully covered; days 21–100 require coinsurance
- 🚫 After day 100, Medicare pays nothing

Requirements to Qualify
Medicare SNF coverage is not automatic. You must meet these specific requirements:
1. Qualifying Hospital Stay (3-Day Rule)
You must have a medically necessary inpatient hospital stay of at least 3 consecutive days (not counting discharge day).
- You must be formally admitted as an inpatient — not "observation status"
- The 3 days must be consecutive; admission counts at midnight
- You must enter the SNF within 30 days of hospital discharge
Common Pitfall: If you are under "observation status" rather than admitted as an inpatient, those days do NOT count toward the 3-day requirement. Always confirm your admission status.
2. Doctor's Orders
A doctor must certify that you need daily skilled nursing care or skilled rehabilitation services.
- Must be ordered by a physician
- Care must be for the same condition treated in the hospital, or a related condition
- Must require professional skilled services (not just custodial care)
3. Skilled Care Requirement
You must need services that require the skills of licensed nurses or therapists on a daily basis.
✓ Skilled Care (COVERED)
- ✓ IV medications and injections
- ✓ Wound care and tube feeding
- ✓ Physical/occupational therapy
- ✓ Monitoring unstable conditions
- ✓ Post-surgery rehabilitation
✗ Custodial Care (NOT COVERED)
- ✗ Help with bathing and dressing
- ✗ Reminders to take medication
- ✗ General supervision
- ✗ Assistance with eating
- ✗ Help walking to the bathroom
What Medicare Covers During Your SNF Stay
When you meet all requirements, Medicare Part A covers:
✓ Covered Services
- ✓ Semi-private room
- ✓ All meals (including special dietary)
- ✓ Skilled nursing care (RN/LPN)
- ✓ Physical, occupational, speech therapy
- ✓ Medical social services
- ✓ Medications during your stay
- ✓ Medical supplies and equipment
- ✓ Ambulance transportation (if needed)
✗ Not Covered
- ✗ Private room (unless medically necessary)
- ✗ Television, phone, personal items
- ✗ Private-duty nursing or aides
- ✗ Long-term or custodial care
- ✗ Care beyond 100 days per benefit period
Understanding Benefit Periods
The 100-day limit applies per "benefit period." Understanding how these work determines when your 100-day clock resets.
What is a Benefit Period?
A benefit period begins the day you are admitted to a hospital or SNF and ends when you haven't received inpatient hospital care or SNF care for 60 consecutive days.
Example Scenario:
- Jan 15: Hospital admission (3-day stay)
- Jan 18: Transfer to SNF, begin using 100-day benefit
- Mar 1: Discharge from SNF after 42 days
- May 5: 60 days pass with no hospital/SNF care → Benefit period ENDS
- May 10: New hospital admission → New benefit period begins, 100 days reset
The 60-Day Reset
- Leave the SNF and stay out for 60 consecutive days → benefit period ends
- New benefit period = fresh 100 days of coverage
- Days 1–20 fully covered again; days 21–100 require coinsurance again
- There is no limit to the number of benefit periods you can have
Important: If you re-enter before 60 days pass, you continue the same benefit period. Used 40 days, left for 30 days, returned = only 60 days remaining.

How to Pay for Days 21–100 Coinsurance
The $204/day coinsurance can add up to over $16,000. Here are your options:
🏆
Option 1: Medigap (Medicare Supplement)
Best Solution: Most Medigap plans cover 100% of SNF coinsurance for days 21–100.
- Plans C, D, F, G, M, and N cover SNF coinsurance
- You pay nothing out-of-pocket (Medigap pays the $204/day)
- Plan G is the most comprehensive for new enrollees
- Must be enrolled before you need skilled nursing care
Note: Plans C and F are only available to those Medicare-eligible before January 1, 2020.

Planning Ahead: Protecting Yourself Financially
Understanding the 100-day limit is just the first step. Here's how to plan ahead:
1. Get a Medigap Policy
When: During your Medigap Open Enrollment Period (6 months starting when you turn 65 and enroll in Part B).
Why: Guaranteed issue — no medical underwriting during Open Enrollment. After this period, you may be denied or charged more.
Best plans: Plan G (most comprehensive for new enrollees) or Plan N (lower premiums, some copays).
2. Consider Long-Term Care Insurance
Covers extended stays beyond Medicare's 100-day limit and custodial care that Medicare doesn't cover.
- Also covers assisted living and home care
- Buy in your 50s or early 60s for best rates
- Can pay $3,000–$7,000 annually depending on coverage
3. Confirm Hospital Admission Status
Critical: Always ask if you are being admitted as an inpatient or placed under observation.
- Request written confirmation of inpatient admission
- If under observation for 48+ hours, ask doctor to admit you as inpatient
- Track your days carefully — count midnight-to-midnight
4. Build Emergency Savings
Recommendation: Set aside $20,000–$30,000 for potential SNF coinsurance and extended care needs.
- Covers days 21–100 coinsurance ($16,320 maximum)
- Provides cushion for costs beyond 100 days
- Peace of mind for unexpected expenses
Important Reminders
100-Day Limit is Firm
Medicare does not cover nursing home, assisted living, or custodial care. This is temporary, post-hospital skilled care only.
3-Day Rule is Strict
Observation status does not count. You must be formally admitted as an inpatient for at least 3 consecutive days.
Days 21–100: $16,000+ Risk
Without Medigap, you pay $204/day. Plan accordingly with supplemental insurance or savings.
60-Day Reset Rule
Go 60 days without hospital/SNF care and your benefit period ends. You get a fresh 100 days when a new period begins.
Frequently Asked Questions
Does Medicare cover assisted living or nursing home care?
No. Medicare only covers skilled nursing care that is medically necessary and ordered by a doctor. It does not cover long-term custodial care in nursing homes or assisted living facilities. If you need ongoing custodial care, you'll need to look into long-term care insurance, Medicaid, or other funding sources.
What if I was under "observation status" instead of admitted?
Observation status does NOT count toward the 3-day hospital stay requirement. You must be formally admitted as an inpatient for at least 3 consecutive days. This is a common issue that can disqualify you from SNF coverage. Always verify your admission status.
Can I reset my 100-day limit?
Yes. Go 60 consecutive days without any inpatient hospital or SNF care, and your benefit period ends. Once a new benefit period begins with a new qualifying hospital stay, you get a fresh 100 days of coverage.
What happens after 100 days if I still need care?
After day 100, Medicare pays nothing. You are responsible for 100% of costs. Options include long-term care insurance, Medicaid (if eligible), personal funds, or returning home with home health services if medically appropriate.
Does the facility have to be Medicare-approved?
Yes. The SNF must be Medicare-certified. Not all nursing homes accept Medicare. Before transfer, confirm the facility is Medicare-certified, has an available bed, and can provide the specific skilled care you need.
Can Medicare deny my SNF claim?
Yes. Reasons include: no qualifying 3-day hospital stay, care considered custodial rather than skilled, you no longer show improvement, or the facility is not Medicare-certified. If denied, you have the right to appeal — the facility must provide a "Notice of Medicare Non-Coverage."
