A SNF (pronounced “sniff”) is a skilled nursing facility, a type of healthcare residence that provides round-the-clock nursing care and rehabilitation services to people recovering from surgery, illness, or injury. Unlike a standard nursing home focused primarily on long-term custodial care, a SNF specializes in medical-level services: wound care, IV therapy, physical and occupational therapy, and monitoring by registered nurses. Most people enter one after a hospital stay, and the goal is usually to recover enough to return home.
What a SNF Actually Does
A skilled nursing facility sits between a hospital and home on the care spectrum. It serves people who no longer need the intensive resources of a hospital but aren’t well enough to manage at home. The federal definition requires that a SNF be primarily engaged in providing skilled nursing care for residents who need medical or nursing care, or rehabilitation services for injured, disabled, or sick individuals.
In practical terms, that means a SNF might care for someone relearning how to walk after a hip replacement, someone who needs daily physical therapy after a stroke, or someone recovering from a serious infection that still requires IV antibiotics. The common thread is that the care requires trained medical professionals, not just help with daily tasks like bathing or eating.
Services You Can Expect
SNFs provide a mix of medical and rehabilitative services. Physical therapy, occupational therapy, and speech therapy are among the most common reasons people are admitted. Residents also receive skilled nursing care such as injections, catheter management, wound care, and medication administration. A registered nurse must be on-site 24 hours a day, seven days a week, available to provide direct care to residents.
CMS finalized staffing standards requiring a minimum of 3.48 total nursing hours per resident per day. Of that, at least 0.55 hours must come from a registered nurse and 2.45 hours from a nurse aide. Each facility also has a medical director who oversees the clinical program, though your day-to-day care is handled by the nursing and therapy staff.
How Medicare Covers SNF Care
Medicare Part A covers up to 100 days in a skilled nursing facility per benefit period. A benefit period starts the day you’re admitted and ends after you’ve gone 60 consecutive days without inpatient hospital or skilled nursing care.
The cost breakdown for 2026 looks like this:
- Days 1 through 20: $0 per day after you pay the $1,736 deductible for the benefit period.
- Days 21 through 100: $217 per day in coinsurance.
- After day 100: Medicare coverage ends. You pay the full cost out of pocket unless you have supplemental insurance.
That coinsurance adds up quickly. If you stay the full 80 additional days (21 through 100), your share alone would be $17,360. Many people carry a Medigap or Medicare Advantage plan that helps cover this gap.
What It Costs Without Insurance
For anyone paying privately, the national average cost for a semi-private room in a nursing facility is roughly $308 per day, or about $112,420 per year, based on the 2024 Cost of Care Survey. Private rooms cost more. These figures vary significantly by state and region, with costs in urban areas and the Northeast running well above the national average.
How People Get Admitted
Most SNF admissions happen through a hospital discharge. When your medical team determines you’re stable enough to leave the hospital but still need skilled-level care, a discharge planner evaluates your needs and presents you with a list of Medicare-participating SNFs in your area (or in whatever geographic area you request). You have the right to choose which facility you go to.
Federal regulations require hospitals to begin discharge planning early in your stay and to involve you and your caregivers as active partners. The hospital must transfer all relevant medical information, including your treatment history, post-discharge goals, and care preferences, to the receiving SNF. If you’re going home afterward, the same planning process applies, and you may be referred to home health services to continue your recovery.
How to Evaluate SNF Quality
CMS rates every Medicare-participating skilled nursing facility on a one-to-five-star scale, published on Medicare’s Care Compare website. The overall rating combines three separate scores:
- Health inspections: Based on findings from the most recent state surveys and any complaint investigations.
- Staffing: Measures the number of nursing hours provided per resident per day, including RN hours specifically.
- Quality measures: Tracks outcomes like rates of falls, pressure ulcers, urinary tract infections, and how often residents are readmitted to the hospital.
A five-star facility performs well above average across all three categories. A one-star facility falls well below. These ratings aren’t perfect, since they rely partly on self-reported data, but they’re the best standardized comparison tool available. When choosing a SNF, checking the star rating is a useful starting point, and visiting in person gives you a feel for cleanliness, staff attentiveness, and overall atmosphere that no rating can capture.
SNF vs. Other Care Settings
The terminology around post-hospital care can be confusing. A SNF is not the same as an assisted living facility, which provides help with daily activities like dressing and meals but does not offer skilled medical care. It’s also distinct from a long-term acute care hospital (LTCH), which handles patients with complex medical conditions that still require hospital-level treatment, like prolonged ventilator weaning.
Some nursing homes have a SNF wing or unit within a larger facility. In that case, the SNF portion is licensed and regulated separately from the custodial long-term care beds. Residents in the skilled unit receive therapy and medical services covered by Medicare. If they transition to long-term custodial care in the same building, the coverage and cost structure changes entirely, often shifting to Medicaid or private pay.
