it all depends on what item number was on the receipt whether medicare will give you your money back...they dont see the referral. they rely on the clinic to get it rigth.
My GP wrote on my letter that i wished to get it done with no fam history or age risks and the clinic that iworked for wouldnt even bulk bll me - i paid and got nothing back. it all depends on the clinic adn their method/interpretation of medicare rules/regulations. And from memory - there are heaps!!
