What quality scores mean for patients at MERCY HOSPITAL OF BUFFALO

MERCY HOSPITAL OF BUFFALO holds a CMS overall rating of 2 out of 5 stars, based on publicly reported quality measures. This places it at #85 out of 131 hospitals in NY. Quality ratings aggregate dozens of individual measures — from nurse communication and cleanliness to surgical complication rates and timely care — into a single composite. While no single number captures the full patient experience, the star rating provides a useful starting point for understanding whether a hospital consistently meets or falls short of national performance standards.

Readmission data offers a particularly important signal. MERCY HOSPITAL OF BUFFALO's average excess readmission ratio is 1.04x the national average, meaning patients here return to the hospital at a higher-than-expected rate after discharge. This hospital reports readmission data across 5 conditions, and performance varies by diagnosis. High readmission rates can indicate issues with discharge planning, follow-up care coordination, or the initial quality of treatment — all factors that may also correlate with the complexity and accuracy of the resulting hospital bill.

Research consistently shows a correlation between hospital operational quality and billing accuracy. Hospitals that perform well on patient safety, infection control, and care coordination tend to have more robust administrative processes, including medical coding and billing. Conversely, facilities with lower quality scores — particularly those with higher-than-average infection rates (0 measures worse than average at MERCY HOSPITAL OF BUFFALO) or elevated readmission ratios — often exhibit higher rates of billing discrepancies. If you have received a bill from a hospital with mixed quality indicators, a line-by-line review against regional benchmarks can identify charges that may not align with the care actually delivered.
