How much are veneers if you have Amelogenesis Imperfecta?

i was born with Amelogenesis Imperfecta which means i was born with no enamel on my teeth (the stuff that makes them white). I had composite veneers put on my teeth when i was 11, im now 26 and its now time i need to look at getting them redone as one has chipped. I have private health cover and am wondering if i will have to pay the same amount as a person who just got it done for cosmetic purposes only?
