A chunk of the 10 percent gain in King of Prussia-based Universal Health Services Inc. a Fortune 500 company and one of the largest hospital management companies in the nation, revenue during the second quarter, compared to the same quarter a year ago, is thanks to the influx of newly-insured patients driven to the market by the president’s health law.

The firm’s chief financial officer, Steve Filton, attributed a third to a half of the quarter’s improvement to Obamacare and said its “final wave of enrollees is ‘starting to filter its way through our business,’” according to a Wall Street Journal earnings report.

Admissions and outpatient surgeries are likewise up over a year ago.

“We’re in the second inning, but, yeah, I think it is hopeful,” Universal CEO Alan Miller said in the article. “This is the best quarter I can remember in a very long time.”
