According to Medicare:
Skin lesions and associated items
We will continue current compliance activities (including audits, recovery and review under the Practitioner Review Program) associated with skin lesion excisions, wounds and cryotherapy.
In 2010–2011 we will develop and implement compliance strategies focussing on upcoding of skin lesion and flap repair items and billing an item that is not substantiated by the required histopathology test.
We released a new eLearning product in late 2009 covering consultation items and the treatment of skin lesions. We will monitor the need for additional education tools to address other aspects of billing for these services.
