I have, our hospital doesn't do scans at all unless its an emergency and if you want a 12 weeks scan you have to pay for it with no medicare rebate unless there is a scare, with mine because they thought my pregnancy was in danger they had a medical reason so I could receive $$ back from medicare. But if I wanted one just for dating & peace of mind I wouldn't receive any back & it was all on what was on the referral.
