BEIJING, March 31 (Xinhua) -- China's National Healthcare Security Administration has exposed eight hospitals involved in medical insurance fraud as part of a nationwide campaign to crack down on the malpractice.

The hospitals were found to have paid kickbacks to village doctors to "buy" patients, over-treated and over-checked patients, booked fake expenditures, or bought fake invoices to defraud medical insurance funds, said the administration.

Institutions and personnel involved in the cases have been dealt with in accordance with the laws and regulations, it said.

China kicked off the campaign in September last year.
