The Association of Private Medical Specialists was formed on September 25, 1998, initially under the name of the Society of Medical Specialists Limited six months earlier. The initial call for registration achieved a membership of nearly 700 members and it has grown substantially over the years. It was formed to represent medical specialists in various disciplines in private practice.

The members are registered medical practitioners in Hong Kong with specialist qualifications as registered with the Hong Kong Medical Council and are engaged in private practice. Colleagues in the University or Hospital Authority managing private patients are also welcome to join the Association.

The Association deals with matters like involvement in forming health policies of the government, apart from its regular scientific sessions. It holds a large annual medical conference of various topics every year at its annual general meeting.
