There evidently is a new clinic in California that does nerve grafts for paralyzed diaphragms, in addition to Dr. Kauffman doing them at UCLA and at his clinic in New Jersey. From reading posts on the facebook page for people with paralyzed diaphragms, I learned that Dr. Kaufman's staff works with his patients' insurance companies to help get them to cover his fee, which I think I read runs over $80,000. You could call his office to see if they take your insurance. However, I also read that the people who answer his phone are not helpful, ie if you are over his cutoff age of 67 or so they will not tell you you aren't eligible...rather you have to send all your paperwork and test results in and have a videoconference just in order for them to tell you you are over the age limit. I haven't read about anyone in MN doing nerve grafts. Where are you thinking about having your plication done in MN if you decide to go that route? Here is the link to the clinic and doctor in California, other than Dr Kaufman at UCLA, supposedly doing phrenic nerve graphs: https://www.losangelesnerve.com/ I know nothing about him...but it's nice to see other doctors are starting to do this important work. If you find any in MN, would you please let us know?
