Your CMS 5-Star Rating Results
Comprehensive Guide to CMS 5-Star Rating Calculation
The Centers for Medicare & Medicaid Services (CMS) 5-Star Quality Rating System is the most important benchmark for evaluating nursing home quality in the United States. This comprehensive guide explains how the rating system works, what factors influence your score, and how to improve your facility’s rating.
How the CMS 5-Star Rating System Works
The CMS 5-Star Rating System evaluates nursing homes based on three key domains:
- Health Inspections (50% weight) – Based on the three most recent health inspections and any complaint investigations
- Staffing (30% weight) – Measures both RN and total staffing hours per resident per day
- Quality Measures (20% weight) – Based on 16 physical and clinical measures for residents
Each domain receives its own star rating (1-5 stars), and these are combined using a weighted formula to calculate the overall rating.
Health Inspection Domain (50% Weight)
The health inspection rating is based on:
- Scope and severity of deficiencies cited during inspections
- Number of deficiencies found
- How recent the deficiencies were identified
- Any substantiated complaints or facility-reported incidents
| Deficiency Scope | Severity Level | Point Value |
|---|---|---|
| Isolated | Minimal Harm | 1-2 points |
| Pattern | Minimal Harm | 3-4 points |
| Widespread | Minimal Harm | 5-6 points |
| Isolated | Actual Harm | 7-8 points |
| Pattern | Actual Harm | 9-10 points |
| Widespread | Actual Harm | 11-12 points |
| Immediate Jeopardy | Any | 13-16 points |
Facilities with fewer than 3 total points from deficiencies typically receive 5 stars, while those with 20+ points receive 1 star. The inspection rating is the most heavily weighted component at 50% of the total score.
Staffing Domain (30% Weight)
The staffing rating considers:
- Registered Nurse (RN) hours per resident per day
- Total nursing staff (RN + LPN + CNA) hours per resident per day
- Staffing levels on weekends
- Staff turnover and retention rates
CMS uses payroll-based journal data to calculate staffing levels. The thresholds for star ratings are:
| Star Rating | RN Hours/Resident/Day | Total Staff Hours/Resident/Day |
|---|---|---|
| 5 Stars | > 0.75 hours | > 4.10 hours |
| 4 Stars | 0.50-0.75 hours | 3.50-4.10 hours |
| 3 Stars | 0.34-0.49 hours | 2.80-3.49 hours |
| 2 Stars | 0.23-0.33 hours | 2.10-2.79 hours |
| 1 Star | < 0.23 hours | < 2.10 hours |
Facilities with higher RN staffing ratios consistently achieve better outcomes and higher star ratings. The staffing domain accounts for 30% of the overall rating.
Quality Measures Domain (20% Weight)
The quality measures domain evaluates 16 different metrics across these categories:
- Short-stay residents (7 measures)
- Long-stay residents (9 measures)
Key quality measures include:
- Percentage of residents with pressure ulcers
- Percentage of residents with urinary tract infections
- Percentage of residents who received an antipsychotic medication
- Percentage of residents whose ability to move independently worsened
- Percentage of residents who were successfully discharged to the community
Each measure is scored based on how the facility compares to national averages, with better-than-average performance earning more points. The quality measures domain contributes 20% to the overall rating.
How the Overall Rating is Calculated
The overall rating uses this weighted formula:
Overall Score = (Health Inspection × 0.5) + (Staffing × 0.3) + (Quality Measures × 0.2)
The weighted score is then converted to a star rating using these thresholds:
- 4.75-5.00 stars: 5 stars
- 3.75-4.74 stars: 4 stars
- 2.75-3.74 stars: 3 stars
- 1.75-2.74 stars: 2 stars
- 0.00-1.74 stars: 1 star

The Impact of CMS 5-Star Ratings
Your CMS 5-Star Rating has significant consequences for your facility:
- Consumer Choice: 87% of families use the rating when selecting a nursing home (AARP study)
- Referral Patterns: Hospitals and physicians prefer to refer patients to 4-5 star facilities
- Reimbursement: Some states tie Medicaid reimbursement rates to star ratings
- Regulatory Scrutiny: 1-star facilities receive more frequent unannounced inspections
- Legal Risk: Lower-rated facilities face higher malpractice insurance premiums
- Staff Recruitment: Top talent prefers to work at higher-rated facilities
- Market Value: Facilities with 4-5 stars have higher valuation multiples in sales
A 2022 study by the HHS Office of the Assistant Secretary for Planning and Evaluation found that nursing homes with 5-star ratings had:
- 23% higher occupancy rates than 1-star facilities
- 18% lower staff turnover rates
- 30% fewer hospital readmissions
- 25% fewer pressure ulcers among residents
Recent Changes to the CMS 5-Star System
