A third of hospitals in England charged for parking last year, with total revenues up by a tenth, according to a survey.
The press association used the freedom of information act to obtain data from more than 140 NHS trusts.
The response showed that 254 million pounds had been raised in 2018-19 - up from 232million pounds a year earlier, charging between 4 and 1 an hour.
An investigation into PA also revealed dissatisfaction with fees.
The poll of more than 7,800 people found that 86% said parking increased their stress to get to the hospital.
Respondents described the fees as "theft", "extortion" and "astronomical".
But people are divided on whether the fees should be scrapped.
Labour has proposed ending hospital charges, while the conservatives have proposed free parking for those most in need, including disabled people, parents of sick children, and people who often need appointments.
Car parks in Scotland, wales and Northern Ireland are generally free.
The patients' association says parking Spaces should be free.
It said: 'hospital parking is charged to people who are unwell and charged for being unwell.'
We believe that patients should not be sued effectively because they are ill, the spokesman said.
Practical facilities can and should be installed in supermarkets, hotels and other places to prevent other drivers from using car parks.
但是代表健康經理的NHS Providers的Saffron Cordery為這些指控辯護。
But Saffron Cordery of NHS Providers, which represents health managers, defended the allegations.
Parking is expensive for the trust that owns it, she said.
Parking facilities must be maintained, well lit and safe. All the fees the trust charges for parking cover the day-to-day running of the hospital's car park, and any surplus will be reinvested into providing a wider range of services for patients or improving these facilities."
Ms Cordery added that abolishing fees would mean trusts would have to look elsewhere for funds, which could "affect patient care".
