Evaluating Skilled Nursing Facilities: A Data-Driven Guide

The terms "nursing home" and "skilled nursing facility" are often used interchangeably, and for good reason — they are typically the same physical building, certified under the same CMS provider number, and staffed by the same clinical teams.

The critical distinction is the type and duration of care being provided, not the facility itself:

• Skilled Nursing Facility (SNF) care — Short-term, post-acute care following a qualifying hospital stay. Focused on rehabilitation (physical therapy, occupational therapy, speech therapy) and skilled clinical services (IV medications, wound care, complex monitoring). Medicare pays for up to 100 days per benefit period.
• Nursing Home (Long-Term Care) care — Custodial care for individuals who can no longer live independently due to chronic illness, disability, or cognitive decline. Primarily covered by Medicaid (for those who qualify) or private pay. Not covered by Medicare beyond the first 100 days post-hospitalization.

When you search for an SNF, you are searching the same database as nursing home searches. This matters because it means CMS quality data — star ratings, staffing levels, inspection results — is identical for both use cases. The key is selecting the right evaluation criteria for your specific need: short-term recovery vs. long-term placement.

For a short-term rehab stay, two data points matter more than any other: the staffing rating and the quality measures most relevant to post-acute recovery.

Staffing Rating: For SNF patients, the ratio of Registered Nurses (RNs) to residents is particularly important. RNs manage complex clinical care — medication regimens, wound assessment, IV therapy — that LPNs and CNAs cannot legally perform independently. When evaluating a facility for short-term rehab, look specifically at the RN hours per resident per day, not just the aggregate staffing score.

Quality Measures for SNF/Rehab Stays: CMS tracks dozens of quality measures across long-term care and post-acute care residents separately. The most relevant for SNF evaluation include:

• Percentage of residents who successfully returned home — A direct measure of a facility's rehabilitation effectiveness.
• 30-day unplanned hospital readmission rate — High readmission rates suggest the facility is not managing post-acute complications effectively.
• Percentage of residents with improvements in function — Tracks mobility, activities of daily living (ADL) performance, and bed mobility gains during the stay.
• Percentage experiencing a fall with major injury — Important safety indicator for rehabilitation environments where patients are mobile but physically compromised.

Weekend staffing is another critical factor for SNF patients. Many facilities maintain strong weekday staffing levels — which are what CMS measures — while cutting staff significantly on Saturdays and Sundays. Ask directly about weekend RN coverage before choosing an SNF.

Medicare Part A covers skilled nursing facility care, but only under very specific conditions. Understanding these rules before a hospital discharge can prevent unexpected bills of thousands of dollars per week.

The 3-day qualifying hospital stay requirement: Before Medicare will pay for SNF care, the patient must have been admitted as an inpatient to a hospital for at least three consecutive days (not counting the day of discharge). Time spent in the hospital under "observation status" — a billing classification that looks identical to inpatient admission from the patient's perspective — does not count toward the 3-day requirement. Always confirm your or your family member's admission status with the hospital billing department.

The 100-day benefit structure: Once the 3-day hospital requirement is met and you are admitted to a Medicare-certified SNF:

• Days 1–20: Medicare pays 100% of covered services. No out-of-pocket cost.
• Days 21–100: Medicare pays all but a daily coinsurance amount (2025 rate: $204/day). Most Medicare Supplement (Medigap) plans cover this coinsurance in full.
• Days 101+: Medicare coverage ends entirely. You are responsible for the full cost or must qualify for Medicaid coverage.

Skilled care requirement: Medicare only covers SNF care for as long as the patient requires "skilled" services — services that can only be provided by or under the supervision of licensed nursing or therapy professionals. Once a patient reaches a stable medical plateau and no longer needs skilled services, Medicare coverage ends, even if they remain in the facility for custodial care.

When evaluating an SNF for a short-term stay, the following patterns in our data — visible on each facility's profile — should prompt further scrutiny before admission:

• Health Inspection rating of 1 or 2 stars. Even if overall or staffing ratings are higher, a low health inspection rating signals recent serious deficiency findings during state surveys. For a short-term stay, you'll be in this facility for weeks — inspection quality matters.
• Any penalty within the last 24 months. Penalties are not issued for minor paperwork violations. They indicate actual harm or immediate jeopardy findings. A facility with recent penalties is statistically more likely to have ongoing systemic issues.
• Staffing rating of 1 or 2 stars combined with high patient acuity. If the facility specializes in complex post-acute care (ventilator patients, complex wound care, IV therapy) but has low staffing ratings, there is a fundamental mismatch between clinical demand and clinical capacity.
• High RN turnover rate. Our profiles show nurse turnover data. High turnover — particularly for RNs — disrupts care continuity and is strongly correlated with worse patient outcomes in post-acute settings.
• Low quality measure scores on functional improvement. If a facility's quality data shows consistently low rates of functional improvement across residents, that is evidence of systematic underperformance on rehabilitation outcomes — the primary reason most patients are admitted to an SNF.

None of these red flags is automatically disqualifying on its own — context matters. A recent penalty that has been fully corrected with a strong compliance history is different from a pattern of repeat violations. Use these signals to prioritize your in-person visits and the questions you ask during facility tours.
