Determining lesion size for MBS item selection

This page provides information on determining the necessary excision diameter for removal of skin lesions

Page last updated: 02 November 2022

This factsheet includes references to the current clinical practice guidelines for existing melanoma MBS items (31356 to 31376) and new clinically suspected melanoma MBS items (31377, 31378, 31379, 31380, 31381, 31382 and 31383). To determine the necessary excision diameter (or defect size) a practitioner should include the lesion size and a clinically appropriate margin of healthy tissue required, with the intent of complete surgical excision.

Practitioners should take measurements before excision with the margin size determined in line with current National Health and Medical Research Council (NHMRC) guidelines.
