Senior managers from St. Vincent's Hospital have agreed to appear before the Public Accounts Committee (PAC). The executives will attend a hearing next month to answer questions about pay levels for some senior managers.
The hospital has insisted it is compliant with public pay rules despite an insistence by the Health Service Executive (HSE) that it cannot use private funds to cover top-up salaries for some managers.
This also follows allegations by Independent Senator John Crown yesterday who said he has evidence that staff at St. Vincent's charged private health insurers for cancer drugs which were free.
He said he first raised the matter 10 years ago but while an investigation was launched, it was subsequently dropped.
Senator Crown is also a consultant at the hospital.
Yesterday the hospital said in reply "The chairman of St Vincent's Healthcare Group...has asked Senator Crown to forward to him, as a matter of extreme urgency, all information that he has in relation to this matter so that it can be fully considered by the board of St Vincent's Healthcare Group".
It added the matter raised by Senator Crown appeared to relate to issues at St. Vincent's Private Hospital that predate the St. Vincent's Healthcare Group.
