When Gordon had his pallidotomies, with Dr. Burchiel at Oregon Health Sciences institute(Oregon medical School), almost four years ago, we looked at a video of one of his patients, #12, I believe. Anyway, that school has been doing this for quite a while. I found out then that the Billing Department of the hospital knows alla about coverages.I don't know where one might go as part of a study, if that angle appeals to you, but someone on this net might--. Dr. B. felt this was the future. Oregon medical School is in Portland, ore. Regards, Thea and Gordon Seese
