(In response to my anonymous poster)
I had surgery in December 2006 for a 2.3cm pituitary macroadenoma. There were no complications, no CSF leak, etc. I stayed overnight at UCSF and was released by 11am the day following surgery. My insurance at the time was Health Net in California. My surgery cost almost $35,000. My copay was $250, that's all I paid out of pocket.
