It's very difficult to say. Every year, Congress passes a one-two year extension to avoid scheduled Medicare cuts. This is not sustainable. However it's anyone's guess to when they will finally consent to cuts. It will probably be a 30% so drop in reimbursement.
Will private insurances follow suit? Probably in time.
The other issue is the inevitable change in fee for service to fee for disease. You will b given a lump sump for each cancer treatment regardless of how it's done. This will probably cut down on over utilization. Also we will like see a rise in professional partnerships between various Oncolgy specialties.
