It will be run by Dr Foster Intelligence, a partnership between the DoH's Information Centre for Health and Social Care and health information provider Dr Foster.
Natalie Robson, marketing communications manager for NHS Choices, said the initial focus would be hospital care but this would be extended to general practice in England.
'Users can leave feedback about their primary care experiences and rate their practice,' she said.
While the practice will be identified, individual GPs would not be named, said Ms Robson. Patient feedback that named GPs would be removed by an independent moderator.
'It is expected that all comments will be moderated before being published on the site,' added Ms Robson.
But GPC chairman Dr Hamish Meldrum said that patient feedback may not provide valuable information to the public. Such a scheme would not provide a representative survey of patients.
'This may attract a fairly select group of people. People tend to report bad experiences rather than good,' he said.
The website could encourage malicious comments from patients, added Dr Meldrum.
'One could have some concerns about the information. I'd rather have evidence-based information, rather than subjective comments from patients.'
