Health Minister Simon Harris has told the Dáil that the Health Service Executive had a deficit of €116 million at the end of April.
"The HSE's latest income and expenditure position of 30 April shows a revenue deficit of €116.2m which represents 2.3% of the available budget," Mr Harris said.
He said the main drivers of the deficit were acute hospitals, the various Medical Card schemes and the Treatment Abroad Scheme.
Mr Harris was responding to Fianna Fáil's Health spokesperson Stephen Donnelly who asked Mr Harris if costs could be decreased, or if the Minister would be returning to the Dáil to approve a supplementary budget.
Mr Harris said his position was to allow the new CEO of the HSE and the new board to do it's own "due diligence".
"I've been very clear to Paul Reid and to the board. We expect them to deliver everything in the Service Plan. So it's not about cut backs or anybody doing less. It's about not doing things that are not costed for," he said.
