At its inception, the MBS was the same as the AMA's equivalent. However, the government has allowed a large gap to grow between the MBS fees and what is charged in the market, in part by freezing indexation of the schedule fees for specialists from 2012 to 2020, and GPs from 2014 to 2020. In 2018 it was suggested that MBS schedule fees are now approximately 45% of the AMA list fees. In 2019, the AMA produced a poster suggesting that if the MBS schedule fees had increased by the same amount as their members' costs, they would more than three times what they currently were.
