A state analysis found Boston-based Partners HealthCare received 31 percent of all the money commercial Massachusetts payers spent on acute-care hospital services last year, according to a Boston Globe report.
The finding is part of the first annual report on Massachusetts' healthcare market, which is required under Gov. Deval Patrick's 2012 healthcare cost-control law.
Partners said it received the majority of payers' acute-care spending because it treats more patients than any other provider in the state, according to the report. A spokesperson for the system said more than 1.5 million patients visit a Partners hospital or physician each year, making the report's results unsurprising.
Partners-affiliated physicians also received 25 percent of the money paid to physicians in 2011, according to the report.
After Partners, hospitals associated with Boston-based Caregroup, including Beth Israel Deaconess Medical Center, received about 10 percent of the money spent on hospital care. Newton-based Atrius Health received 11 percent of all dollars spent on physician services.
Overall, 80 percent of insurance payments went to Massachusetts providers that charge the highest prices, including Partners, Pittsfield-based Berkshire Health Systems, and Atrius, according to the report.
Massachusetts' newly formed Center for Health Information and Analysis prepared the report.
