Does anyone know of any major differences between them in terms of testing, treatment, etc.? I know that Dr. Kauman's initial visit is close to $500, and I was told they will be raising this very soon to around $525. I'm going to e-mail Dr. De Meirleir's asst to get the cost for a visit to him in Reno. I am concerned about the cost of lab tests. I'm on Medicare, which does cover a lot of lab work, but I have no idea if it covers any of these doctors' testing. I believe that a doctor can refuse to accept Medicare for medical treatment, but still have his labs covered - does anyone know if this is true or not? I know @Mouse girl asked a similar question about Medicare paying for labs last March, but I didn't see where anyone really knew the answer. Besides the costs, I would be very interested in anything pertaining to differences between the two doctors re testing and treatment etc. Thanks!
