I just got off the phone will Dr. Johnson in SLC, Utah. I asked him if liver illnesses were one of the treatable conditions with HBOT. He said it is not recognized in that application although there was a person with a liver condition that receive HBOT and his condition improved. (don't know if the liver condition is for sure credited to HBOT.)
Dr. Johnson did say that there are 15 or 16 conditions that are treatable with HBOT that are recognized and covered by insurances including Medicare.
Said there are currently about 600 hospitals around the country that use HBOT.
Sorry I took so long posting but it took awhile to hear from Dr. Johnson. He allowed a reasonable amount of time to ask him questions and said to call back anytime. 801-964-2008
