Bill...… I'm interested in what you find out at UC Davis. I live in the Sacramento area and have Kaiser Senior Advantage insurance. They will not cover a CI for me. The quote that I got from a man who recently had an implant was $20,000 per ear for self pay clients. That is very expensive but I will have to consider it if I get to the point of qualifying for an implant. The man that I spoke with said that his hearing went from 25% to 65% and it was well worth the cost to him.
