Prediction of <scp>MBS</scp> Item Codes for Endometriosis Surgery Using Transvaginal Ultrasound

The IDEA consensus-based rASRM-U has relatively poor agreement with corresponding MBS item numbers, tending to predict 'higher' stages. This model is unlikely to predict low stages incorrectly. Although unable to accurately predict individual item numbers for endometriosis surgery, this system identifies high versus low surgical complexity when ultrasound and surgical groups are dichotomized; thus, it could allow improved surgical and financial planning.
