The head of the HSE will meet the Chairman of St Vincents Healthcare Group this morning over salary top-ups.
CEO Nicholas Jermyn was in receipt of a salary of almost 300-thousand euro last year - which includes 136-thousand from private funds.
Last month, it was revealed that St Vincent's CEO Nicholas Jermyn earns almost 300-thousand euro per year - which includes 136-thousand euro from his publically-funded salary - as well as 136-thousand euro in top-ups from private funds - and 20-thousand euro for car allowance.
The Public Accounts Committee says both the HSE and St Vincent's have more questions to answer over the scale of the payments.
And this morning, HSE Chief Tony O'Brien will meet Mr Jermyn and other representatives of the St Vincent's board today to discuss the top-ups.
Mr O'Brien is expected to ask them how they plan to become compliant with public sector pay rules.
The board of St Vincents has maintained that the salaries are all tax compliant - and are not funded by charitable donations.
They're likely to face even more questions about the top-ups later this month - when hospital officials are called to re-appear at the Public Accounts Committee next week.
