Joyce- Sorry I took so long in replying. The pallidal-stimulation surgery was done at KU in Overland Park , Ks. It was done in two operations one on the left side of my brain and one on the right. The left side was done in Dec. of 95 and right in Jan of 96. I do not know the code they used but I was covered by Health Net. I might mention that insuance in general covered the first 5 operations but that medicare decided not to cover the procdure so the other companies followed suit. Dick
