There is a way the gp can request the combined screening test that it is bulk billed. But generally there is a gap. It is usually only deemed a necessary test if there is string family history of genetic anomalies that can be detected by that screening test. For me, with DD, it was bulk billed due to family history. I was advised by the gp that it was only being written up the way it was because of that history. Otherwise it would have cost about $100 even three years ago. I'm not sure why you wrent charged in the past.

Even though it is routinely actioned, the tests aren't a standard part of the governments recognised prenatal care structure so the charging stands.
