Montserrat Day Hospital provide a $99 vasectomy service for men with private health insurance (plus any applicable PHI excess - mine is nil).
This is done using the scalpel free method as day surgery.
Regular cost outside hospital is about $500 with a small Medicare rebate.
Sedation/general anesthetic is additional: I had full sedation which was a $150 gap as there is an anesthetist present during the entire procedure: this is optional and more than 80% of men have it without apparently.
Includes a bonus of 'no more kids' which will save you $$$ in the long run :)
Looks like the sedative hasn't quite worn off yet.. :)
