There are broadly two types of medical aids – open and restricted. The latter, restricted medical aids, cater for only specific groups, be it the employees of certain companies, industry workers or those belong to specific organisations. One type of restricted medical aid is that for professionals. This refers to technikon (technical university) and university graduates who have completed a degree encompassing at least 4 years of study. There are several benefits to joining a medical aid for professionals as they are restricted schemes with a very exclusive member base.
