Cost report, against California
Each line is what this building filed with Medicare for its latest full year, beside the middle building in California. The rank counts from the top: 1st is the highest figure among California's filing buildings on that line, out of the buildings that filed it. The arrow beside a figure compares it with the building's own full year before: green is better, red is worse, grey is neither. Shares and margins move in points. A line standing on fewer than 20 filings is not ranked. Operating expense is the cost report's own operating line. Net income also counts income and expense outside patient care, such as investment income, rentals and donations, which is why it is not patient revenue minus that line. The switch shows the Medicare report, California's own Medicaid cost report, or both side by side. A check means California's filing is within 5 points of the Medicare figure (10% on a dollar line); a not-equal sign means it is further apart, or that one report shows a profit and the other a loss. The state's filing usually covers an earlier year.

CMS sets the overall star rating from health inspections, staffing and quality measures. The occupancy percentage is not the star rating. Occupancy compares average residents with certified beds. Certified beds can include beds the home chooses not to fill; this figure does not tell us why beds are unused.
