Medicare also going over the "cliff"

I'm a doctor.  I have a practice that's mostly Medicare.  For several years it has been a "loss leader" for my other job, that pays better -- being Medical Director for a company that does drug trials, paid for by big drug companies.  
In about 2003 Congress created a "sustainable growth rate" (SGR) formula for Medicare payments.  Basically, if Medicare expenses per person insured went up more than inflation, what Medicare paid the next year would be reduced by enough to bring it back down.  That passed the buck for staying within budget to doctors and patients -- collectively.  There's no way to enforce that "budget".
Every year, when the SGR reduction reared its ugly head, Congress kicked the can down the road.  
This year, I really don't trust them to do it.
