The 100-Day Rule: Skilled Care vs. Custodial Care
Medicare is very specific about the type of care it covers in a nursing home or skilled nursing facility (SNF). It is crucial to understand that Original Medicare (Part A) only covers short-term, medically necessary stays for skilled care, not long-term or custodial care. The maximum coverage per benefit period is 100 days.
- Skilled Care: This requires the daily services of professional staff, such as registered nurses or physical therapists. Examples include physical therapy, IV injections, or complex wound care following a surgery or illness.
- Custodial Care: This refers to assistance with daily living activities (ADLs), such as bathing, dressing, and eating, that can be provided by non-medical staff. Medicare does not cover custodial care if it is the only care you need.
What is a Medicare Benefit Period?
Medicare tracks your skilled nursing care using 'benefit periods'. A new benefit period begins when you are admitted as an inpatient to a hospital or a SNF. It ends only after you have gone 60 consecutive days without any inpatient hospital or skilled nursing care. This means you can have multiple benefit periods within a single calendar year, each with its own 100-day limit and deductible.
Qualifying for Medicare Skilled Nursing Coverage
To receive Medicare coverage for a skilled nursing stay, you must meet several requirements:
- Have a qualifying hospital stay of at least three consecutive days as an inpatient (not observation status).
- Be admitted to a Medicare-certified SNF within 30 days of leaving the hospital.
- Require daily skilled nursing or rehabilitation services for a condition that was either treated during your qualifying hospital stay or started while you were receiving care in the SNF.
- Receive care in a Medicare-certified SNF.
Understanding Your Costs: Days 1-20 vs. Days 21-100
During a single benefit period, your out-of-pocket costs for skilled nursing facility care change significantly over time. The structure is designed to help with short-term, intensive care but places a greater financial burden on longer stays.
Cost-Sharing for a Skilled Nursing Facility Stay
| Duration of Stay (per benefit period) | Your Daily Cost (for 2025) | What it Covers |
|---|---|---|
| Days 1–20 | $0 | All covered services. (Note: This is after meeting your Part A deductible, which you typically pay during your hospital stay). |
| Days 21–100 | $209.50 coinsurance | All covered services. |
| Day 101 and beyond | All costs | All costs for your stay are your responsibility. |
It is important to remember that these costs are for covered skilled services only. Additional charges for non-covered items like a private room, phone, or laundry services are always your responsibility.
The “Myth” of 100 Days
It is a common misconception that Medicare automatically covers a full 100 days of SNF care. Coverage can end at any time within that 100-day period if you no longer require daily skilled care. For instance, if you plateau in your recovery and are no longer benefiting from daily therapy, your coverage can cease. You may be able to appeal this decision, but it is not a guarantee of extended coverage.
Planning for Extended Care: Your Options When Medicare Stops Paying
Since Medicare's coverage is so limited, planning for long-term care is crucial for many seniors. Here are some of the most common alternatives:
- Medigap Supplement Plans: Private insurance policies that can help pay for out-of-pocket costs not covered by Original Medicare. Some plans may cover the daily coinsurance for days 21-100.
- Medicaid: A joint federal and state program for low-income individuals. If you qualify, Medicaid can cover long-term custodial care in a nursing home. Eligibility rules are strict and vary by state.
- Long-Term Care Insurance: A private insurance policy specifically designed to cover long-term care services, including nursing home stays and home healthcare.
- Veterans Affairs (VA) Benefits: Eligible veterans may receive assistance with short-term and long-term care services through the VA.

What About Medicare Advantage Plans (Part C)?
Medicare Advantage Plans, offered by private insurance companies, must cover at least the same services as Original Medicare (Parts A and B). However, their specific cost-sharing rules for skilled nursing facilities may differ. For example, they may have different copay structures or require you to use specific in-network facilities. It's essential to check the specific policy details of your Medicare Advantage plan to understand its SNF coverage.
Conclusion
Navigating the complexities of Medicare coverage for nursing home care is a critical part of financial and healthcare planning for seniors. While Medicare provides valuable coverage for short-term, skilled rehabilitation after a hospital stay, it is not a solution for long-term needs. Understanding the 100-day limit, the benefit period rules, and the distinction between skilled and custodial care is key to making informed decisions. By exploring additional options like Medigap, Medicaid, or long-term care insurance, you can be better prepared for the future. Proactive planning ensures you can access the care you need while protecting your financial security.
