Private hospitals should publish prices of all medical and non-medical services, a patients' group said last night.
The Patients Rights Association said the Consumer Council should investigate whether the practice of not identifying costs item-by-item was common.
'The Consumer Council must look into the matter seriously,' spokesman Ho Hei-wah said.
'Moreover, even when prices of the items are listed openly, the council has the obligation to determine whether the prices are justifiable.
'It has been the belief that private hospitals tend to be more expensive and most people will simply pay a lump sum as laid out in the bill when they are discharged, with no questions asked.' Mr Ho urged the Department of Health, which monitors private hospitals, to investigate whether hospitals over-charged.
