The main member is the person who is the holder of the medical aid account. The main member chooses who will be dependants on his or her medical aid.

In GoodX, the main member is set up as the Debtor and the dependants are set up as patients under the main member's account. The main member's medical aid will be charged for the account of the main member or dependant as sent via switching or paper claim by the practice.

However, unless the main member accepts responsibility in writing for the account of an adult dependant, or is a guardian of a minor dependant, he or she will not by default be liable for the account of a dependant.
