Coverage overlaps, but broadly: Northwell dominates central and western Nassau and much of Suffolk, plus the North Fork via Peconic Bay Medical Center in Riverhead. Catholic Health covers central Nassau and western-central Suffolk, including Rockville Centre, Roslyn, West Islip, Smithtown, Port Jefferson, and Bethpage. Stony Brook Medicine covers central and eastern Suffolk plus the South and North Forks. NYU Langone covers Mineola and central Nassau, with a Suffolk presence as well.
Inside the discharge window
Knowing which hospital system is most likely to serve your family's area on Long Island can help you understand discharge planning and post-acute care referral patterns before a crisis happens, rather than during one. Catholic Health, sponsored by the Diocese of Rockville Centre, runs five hospitals across six campuses spanning from Rockville Centre and Roslyn in Nassau to Smithtown and Port Jefferson in Suffolk. Stony Brook Medicine, part of SUNY, anchors central and eastern Suffolk with its flagship 624-bed Level 1 Trauma Center in Stony Brook, plus Southampton Hospital on the South Fork and Eastern Long Island Hospital in Greenport on the North Fork. NYU Langone's flagship Long Island campus is in Mineola, formerly Winthrop-University Hospital, home to Nassau County's only adult Level 1 Trauma Center. Because exact service areas and hospital affiliations shift over time, it's worth confirming which system covers a specific hospital before assuming coverage based on general geography.
