Diamondback Healthcare Center's upper-tercile CMS stars
Quality ratings
The rating comes from CMS's most recent Care Compare release (data as of April 2026). CMS rolls three sub-ratings into the overall star: health inspection, staffing, and quality measures. The chart below sets each of them against the Arizona average.
What each sub-rating measures
The health inspection rating reflects on-site surveyor findings from the last three cycles. The staffing rating compares case-mix-adjusted nurse hours per resident day to national benchmarks, and quality measures aggregate 15 clinical indicators including pressure ulcers, falls with injury, and long-stay antipsychotic use.
Size and setting
Located in Phoenix, Arizona. Bed capacity and average daily census, where CMS reports them, are in Facility details below. Its ownership type, listed in Facility details, can influence staffing patterns, reinvestment decisions, and admissions policy. Occupancy of about 90% puts this facility in normal territory for a stabilized operation, neither unusually full nor unusually empty.
Same-ownership peers
Within Arizona, Diamondback Healthcare Center is one of 62 for profit - corporation nursing homes CMS rates. Its 5-star overall rating sits above the for profit - corporation-segment average of 3.6 stars, ahead of roughly 65% of same-ownership peers in the state. Same-segment comparisons like this one strip out the business-model factor, leaving a cleaner read on facility-level performance than a raw state average would give.
Inspection record
On the regulatory side, federal and state surveyors have documented a moderate number of deficiencies at this facility; the counts are in Facility details below. CMS has levied enforcement penalties - civil money penalties or denials of payment, during the same window. This volume of findings is worth reading past the count: CMS's F-tag scale separates isolated, low-harm citations from widespread or immediate-jeopardy ones, and only the full report shows which this facility has.
