Just remember to keep that R1k aside for medical expenses that would have been paid from savings.
I am at the moment on a Comprehensive Classic. The Comprehensive Zero MSA did not exist until now (at least I have not heard of it until Sinbad mentioned it). I am still not sure if
that link's info is correct - for example the "Upfront payments to hospitals"-sections seems to indicate that the Comprehensive Classic Zero MSA does not require upfront payment whereas the other Comprehensive ones do.
So in case of Comprehensive Zero MSA I would still pay upfront, submit the claim and once my claims reach the annual threshold Discovery would refund? I am asking this, as even when visiting ER at Fourways Lifestyle (they are part of the Delta Network) I had to pay for the ER charges (treatment for possible rabbies - don't ask) as well as all medication. Claims were refunded much later.
Other than the odd case at Clicks where I was able to offset medication via medical it's always pay upfront and claim later (Intercare in Fourways is another example). So perhaps one would also have to selective pick practitioners which contract with Discovery, but it seems the ones I pick don't seem to want anything to do with Discovery. Regardless of what scheme I was on, I always felt like I was getting shafted and not really getting value for money. Latest example was an eye-infection where I needed cortison drops (at 200 bucks a bottle) over a treatment course of 8 weeks (you use one bottle of eyedrops in 10 days) - but guess what, Discovery only covers that type of repeat medication every 17 days.
But one can't go without medical cover either - that's a step away from bankruptcy if something goes belly-up. (Two cases of cancer in circle of friends in the last two months and both on basic medical aid - will financially ruin those families now).
