Understanding your first 100 days - what Medicare covers, what you'll pay, and how to protect yourself financially.
Last reviewed February 2026 by Dev Gaymes, Licensed Insurance Advisor · Editorial policy
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.
Medicare's skilled nursing facility coverage is divided into distinct periods, each with different cost-sharing requirements.
| Medicare Pays | 100% |
| You Pay | $0 |
Room, meals, nursing care, therapy, medications, supplies - all covered.
| You Pay (2026) | $204/day |
| Monthly Cost | ~$6,120 |
| 80-Day Max | $16,320 |
| Medicare Pays | $0 |
| You Pay | 100% |
| Typical Cost | $300–$500+/day |
Medicare SNF coverage is not automatic. You must meet these specific requirements:
You must have a medically necessary inpatient hospital stay of at least 3 consecutive days (not counting discharge day).
A doctor must certify that you need daily skilled nursing care or skilled rehabilitation services.
You must need services that require the skills of licensed nurses or therapists on a daily basis.
When you meet all requirements, Medicare Part A covers:
The 100-day limit applies per "benefit period." Understanding how these work determines when your 100-day clock resets.
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.
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.
Here's what you would pay in different scenarios:
The $204/day coinsurance can add up to over $16,000. Here are your options:
Note: Plans C and F are only available to those Medicare-eligible before January 1, 2020.
Understanding the 100-day limit is just the first step. Here's how to plan ahead:
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).
Covers extended stays beyond Medicare's 100-day limit and custodial care that Medicare doesn't cover.
Critical: Always ask if you are being admitted as an inpatient or placed under observation.
Recommendation: Set aside $20,000–$30,000 for potential SNF coinsurance and extended care needs.
Medicare does not cover nursing home, assisted living, or custodial care. This is temporary, post-hospital skilled care only.
Observation status does not count. You must be formally admitted as an inpatient for at least 3 consecutive days.
Without Medigap, you pay $204/day. Plan accordingly with supplemental insurance or savings.
Go 60 days without hospital/SNF care and your benefit period ends. You get a fresh 100 days when a new period begins.
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.
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.
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.
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.
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.
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."

You must have a medically necessary inpatient hospital stay of at least 3 consecutive days (not counting discharge day) to qualify for Medicare skilled nursing facility coverage. Observation status does NOT count toward this requirement.
Days 1-20 are fully covered by Medicare ($0 cost). Days 21-100 require $204/day coinsurance (2026 rate), totaling up to $16,320. After day 100, Medicare pays nothing and you pay 100% of costs, typically $300-$500+ per day.
The best option is a Medigap (Medicare Supplement) policy-Plans C, D, F, G, M, and N cover SNF coinsurance. Plan G is the most comprehensive for new enrollees. Medicare Advantage plans and Medicaid may also help cover costs.
