Section 28 of the Medical Schemes Act states very clearly that…
28 Prohibition of membership of, and claims against, more than one medical scheme
No person shall-
(a) be a member of more than one medical scheme;
(b) be admitted as a dependant of-
(i) more than one member of a particular medical scheme; or
(ii) members of different medical schemes;
Very clearly then a patient may not belong to more than one medical aid.
