If, for NA I use a doctor who takes medicare, will the medicare pay for the entire procedure, or will I have to pay more out of pocket?

Same for Xiaflex--does Medicare cover whole treatment or is there out of pocket expense?

Also, I haven't visited the forum for several months. I now notice that Dr. Charles Eaton is no longer listed as doing NA--and neither is is partner. This is a shock to me. Does anyone know why?

With thanks
