A skilled nursing facility (SNF) is a type of nursing home, but not every nursing home is a SNF. The two terms overlap because many buildings operate as both, often under the same roof. The real difference comes down to the level of medical care provided and how that care gets paid for.
How a SNF Differs From a Standard Nursing Home
A SNF provides hospital-level nursing care in a residential setting. Registered nurses deliver medical treatment under a doctor’s supervision, and licensed therapists offer physical, occupational, and speech therapy. The goal is typically recovery: helping someone regain function after a surgery, stroke, or serious illness so they can eventually go home or step down to a lower level of care. The average Medicare-covered SNF stay lasts about 28 days.
A standard nursing home, by contrast, focuses on what’s called custodial care. Licensed practical nurses and nurse aides help residents with daily activities like bathing, dressing, eating, and moving around. Residents in custodial care generally aren’t expected to recover and leave. They need ongoing assistance because of age, chronic illness, or disability. This is long-term care, and some people live in nursing homes for years.
The confusion between the two is understandable because a single building often houses both. Federal regulations allow a facility to have a “distinct part” that is certified as a SNF while the rest operates as a standard nursing facility. Those sections must be physically separate, with beds that aren’t mixed together, and they’re tracked separately for billing purposes. So you might visit what looks like one nursing home and find that one wing handles short-term rehabilitation patients on Medicare while another wing provides long-term custodial care funded by Medicaid or private pay.
Staffing Requirements
SNFs must meet stricter staffing standards than many people realize. Under a final rule from CMS, long-term care facilities must provide at least 3.48 hours of direct nursing care per resident per day. Of that total, at least 0.55 hours must come from registered nurses and 2.45 hours from nurse aides. The remaining time can be filled by any combination of RNs, licensed practical nurses, or aides. CMS also requires a registered nurse to be on-site 24 hours a day, seven days a week, available to provide direct care to residents. That RN can be the director of nursing, but they can’t just handle administrative work; they must be available at the bedside.
What Medicare Covers in a SNF
Medicare Part A covers SNF stays when the care is medically necessary and skilled in nature. During a covered stay, Medicare pays for the room, nursing care, physical and occupational and speech therapy, medical equipment, supplies, and medications administered in the facility.
The cost-sharing structure works on a countdown. For days 1 through 20, you pay nothing beyond the Part A deductible ($1,736 in 2026). From days 21 through 100, you’re responsible for a daily copay of $217 in 2026. After day 100, Medicare stops covering SNF care entirely for that benefit period. Most rehabilitation stays fall well within that window, but if you need care beyond 100 days, you’ll need another funding source.
How Long-Term Nursing Home Care Gets Paid For
Here’s where the financial picture shifts dramatically. Medicare does not cover long-term custodial care. If someone needs to live in a nursing home indefinitely because they can no longer manage daily life on their own, Medicare won’t pay for it, no matter how long they’ve been paying into the system. This catches many families off guard.
Medicaid is the primary payer for long-term nursing home stays. It’s a needs-based program, meaning eligibility depends on both income and assets. Each state sets its own thresholds, but most require applicants to have very limited savings and income. Many people who enter a nursing home start by paying privately and eventually “spend down” their assets until they qualify for Medicaid. Some states also offer Medicaid-funded home and community-based services as an alternative to placement in a facility, allowing people to receive care at home instead.
Services You Can Expect in a SNF
SNFs are built around active treatment. A typical stay involves daily therapy sessions designed to rebuild strength, mobility, or communication skills. Physical therapy might focus on walking safely after a hip replacement. Occupational therapy helps people relearn tasks like getting dressed or cooking. Speech therapy addresses swallowing difficulties or language problems after a stroke. These sessions are intensive, often an hour or more per day, and progress is tracked closely. If a patient stops making measurable improvement, Medicare coverage can end even before the 100-day limit.
SNFs also handle complex medical needs that go beyond what a standard nursing home provides: wound care, IV medications, injections, tube feedings, and monitoring of unstable conditions. The facility functions as a bridge between the hospital and home, delivering medical-grade care in a less acute setting.
Choosing Between a SNF and a Nursing Home
In practice, you rarely choose one or the other in isolation. If you’re being discharged from a hospital after a qualifying stay and need ongoing skilled care, the hospital’s discharge team will help arrange a SNF placement. The SNF stay is temporary by design. Once you’ve recovered enough, you go home, possibly with outpatient therapy or home health visits to continue your progress.
If the situation is different and a family member can no longer live safely at home due to dementia, frailty, or chronic conditions requiring around-the-clock supervision, that’s a nursing home conversation. The care is custodial, the stay is open-ended, and the funding comes from a completely different source. Many families explore home-based care or assisted living first, since nursing homes represent the highest and most expensive level of residential care.
Because so many facilities are certified as both a SNF and a nursing facility, the building you visit for post-surgical rehab could be the same one where a long-term resident has lived for three years. The difference isn’t always the address. It’s the type of care being delivered, who’s delivering it, and who’s paying the bill.
