PLTLea, We had no problem with Medicare covering HBOT. Once oral surgeon recommended extraction, radiation oncologist ordered the HBOT, and HBO office submitted for approval from Medicare. 3 days later approval was received.

Our oral surgeon does not participate in Medicare. Not sure under what circumstances, if any, Medicare would cover dental services.

I suggest that you seek out advice from the Head & Neck Department of a Comprehensive Cancer Center, even if you do not end up going there. The patient coordinator at Dana-Farber Cancer Center in Boston facilitated a dental consultation for us. I spoke to their financial department and they submitted directly to Medicare and think that the consultation fee will be covered. The CCCs have more resources and experience in handling complicated situations. Sometimes a case & x-rays can be reviewed electronically, but I don't know how payment works.

Let me know if I can try to help answer anything else,
