I did read the other day that some procedure charges are out of date. Technology has improved which has resulted in procedure time being reduced but schedule fees have not been reduced. This isn't fraud because the practitioner is only claiming the allowable amount. This is the Gov's fault for not moving with the times, as no Gov departments seem to lol
Anyway, this article is from 2004 so you can imagine the problem has got worse.
I don't see what Medicare fraud has to do with multiculturalism. Unless Redmoki is claiming that the most prevalent fraudulent practitioners are from non Australian extract. Is their a link to any statistics?
