Choosing a hospital in Westchester County

When comparing hospitals, review the CMS overall rating and the underlying measure groups, confirm that the services you need are offered, and check whether the hospital participates in your insurance network. Ratings are signals, not medical advice.

Start by comparing CMS Five-Star ratings, which summarize health inspections, staffing, and quality measures. A high overall rating is a useful signal, but read the underlying inspection findings and staffing figures too - they show what is behind the score.

Families in Westchester County should ask about Medicare and Medicaid participation, current openings, care planning, and how concerns are escalated after hours. In-person visits and direct questions remain the most reliable way to judge fit.
