Imagine thousands of surgery centers spread across the U.S., performing millions of procedures each year. These aren't traditional hospitals, but ambulatory surgery centers (ASCs). They specialize in less invasive surgeries that let patients go home the same day. Over 9,000 of these ASCs are active, according to Definitive Healthcare.

For the fifth year, Newsweek and research firm Statista joined forces to rank the best ASCs. This year's list has expanded to include 650 centers. Why care about rankings? It's simple: they help you make wise choices about your healthcare, or that of your loved ones.

The top centers weren't chosen lightly. Over 5,000 ASCs were evaluated on factors like care quality, patient experience, performance data, and what their peers think.

Here's how they did it: Statista surveyed medical professionals, and CMS (Centers for Medicare & Medicaid Services) provided quality metrics. They also looked at patient reviews and accreditation certificates.

By grouping states into regions and considering each ASC's score in these areas, they created a ranking. California led with 118 top centers, while Mississippi had 5.

It's crucial to remember these rankings are a snapshot of the past year. Healthcare centers evolve, and new data might change the picture. Always combine these rankings with other info and, if possible, visit the centers yourself.
