NEW YORK (CBS 2) — It’s a controversial move to help close New York City’s budget gap.

The City reportedly will begin charging private hospitals up to a million dollars a year for ambulances dispatched by the 9-1-1 system.

According to Thursday’s Wall Street Journal, the Fire Department, which runs emergency medical services, began alerting hospitals to new policy earlier this month.

Some medical professionals said they worry the fees will prompt some private hospitals to stop providing ambulance service.
