Doctors charging patients thousands of dollars out-of-pocket have been put on notice, with the federal government promising to publish their fees for procedures to expose exorbitant billing.

The Morrison government has pledged to build a searchable website that will list individual specialists' fees for specific services to help patients avoid “bill shock” and crackdown on doctors charging egregious out-of-pocket sums.

The first specialists under the microscope will be gynaecologists, obstetricians and doctors working in cancer services - including urological surgeons and breast cancer specialists - following multiple reports of price-gouging within these professions.

The Ministerial Advisory Committee’s report into out-of-pockets costs released on Saturday confirmed some specialists are charging patients massive and unexpected fees that were not covered by Medicare or private health insurance policies.
