How we rank
Each practice on NYC Hot List shows its Google rating and review count. We rank practices with at least 20 reviews using a weighted rating: a 4.9 from 900 reviews ranks above a 5.0 from 25, because more reviews make a rating more reliable. In formula terms, each rating is blended with the in Union Square average (4.5) as if it had 75 extra average reviews.
Paid Featured placement is shown separately and labeled Sponsored. It never changes this ranking, a rating or a review. Ratings refresh as practices update; this list was last rebuilt in November 2026. Ratings describe past patients' experiences, not medical outcomes. Always ask who will treat you and check their license.
