Some 5.1 million euro was taken in by the HSE in car parking charges in its public hospitals in 2021, which is almost identical to the previous year.
The money relates to 21 statutory hospital car parks.
By far the highest was the €1.25 million euro in Cork University Hospital.
That's followed by €657,000 in Galway University Hospital, and €468,000 in Waterford Regional Hospital.
Aontu put forward a bill in the Dail last month that would see the charges end for many patients attending outpatient services.
