Wow! I have Medicare and the Supplemental to cover everything else Medicare doesn't pay for, and I'm going through the same teeth nightmare. I need ALL my teeth taken out, which are in disrepair and down to the gum line, and have three teeth infected now. Mine is being putting off due to microscopic cancer, and can't do HBO until after chemoradiation treatment due to it feeding cancer. I hope I have no problems, and had HBO previously, but had insurance with my employer. The wound management doctor then, where HBO is associated with sometimes, said it has to be put in properly otherwise insurance may deny it cause its expensive, $2000 for each session. I had no problems.

Thanks for the heads up.
