I am having my radiation at a private facility but Medicare actually pays for it, not my health fund. The total cost is around $16000 and I will be out of pocket $3000 - Medicare pays the rest. The radiation clinic should go through a fee schedule with you and work out a payment plan. I was told that I would never be denied treatment if I was unable to pay - I don’t know how that would work and fortunately I am able to afford the cost. Talk to the clinic as well as your health fund because I don’t think you’ll need the fund.
