vitamins-price discounts from medical insurers

[joeleighton]

I understand that discounts provided by private medical insurance are a major driver for the vitamins and dietary supplements market in SA.

Cannot find specific guidance online, but I'm assuming the concept is something like "a certain percentage of expenditures is reimbursable for products with NAPPI codes."

Any guidance in this regard much appreciated...such as:

Is there a rule of thumb percentage of discount?

Is discount claimed at point of sale or by submitting documentation to the insurer? ...or both?

thanks in advance, joe
