What do CMS star ratings mean for nursing homes?

CMS star ratings (1–5 stars) rate Medicare-certified nursing homes on three factors: health inspections (state survey citations and complaint investigations), staffing (nurse and aide hours per resident per day), and quality measures (outcomes like falls, pressure ulcers, and rehospitalization rates). A 5-star overall rating indicates above-average performance across all three categories. The health inspection rating is the most meaningful — it reflects actual deficiencies found during state surveys.

Is a 4-star nursing home good?

A 4-star nursing home is above average, but the star rating alone isn't sufficient for a placement decision. Read the health inspection detail — a 4-star home with recent serious deficiencies in abuse or neglect categories warrants scrutiny. Compare staffing hours to state and national averages. Visit in person. Star ratings are updated periodically and can lag behind recent events. Use the stars as a starting filter, not a final answer.

Do CMS star ratings apply to assisted living communities?

No. CMS star ratings only apply to Medicare-certified skilled nursing facilities (nursing homes). Assisted living is regulated at the state level, not by CMS. For assisted living inspection records, use your state's licensing portal directly or AllyKin's 50-state facility safety lookup at /facility-safety/license-lookup. The inspection records, survey frequency, and enforcement standards vary significantly by state.
