Hyperbaric Oxygen and the "noncovered conditions"

Hyperbaric Oxygen Therapy (HBOT) is quite useful for a number of conditions, though the medicare laws have a curious and unusual statement about HBOT: a non-covered conditions list. Most therapies' entries in the medicare laws don't even list covered conditions, so why does this specifically name 22 conditions as being "non-covered"? This is especially interesting because the 22 conditions are all clearly effectively treated by HBOT.
The last issue of Hyperbaric Medicine Today has an interesting article about how this happened. You can go read it yourself at
http://www.hbomedtoday.com/PDF/HBOMT_8.pdf The article starts on page 7, you'll have to scroll down to it in the acrobat file yourself. Interesting reading.
If you'd like to read some information about HBOT by physicians who use it, try
here. You can read a (relatively) short bibliography of research on HBOT here.

Here is the medicaid list of noncovered conditions:
1. Cutaneous, decubitus, and stasis ulcers
2. Chronic peripheral vascular insufficiency
3. Anaerobic septicemia and infection other than clostridial
4. Skin burns (thermal)
5. Senility
6. Myocardial infarction
7. Cardiogenic shock
8. Sickle cell anemia
9. Acute thermal and chemical pulmonary damage, i.e., smoke inhalation with pulmonary insufficiency
10. Acute or chronic cerebral vascular insufficiency
11. Hepatic necrosis
12. Aerobic septicemia
13. Nonvascular causes of chronic brain syndrome (Pick's disease, Alzheimer's disease, Korsakoff's disease)
14. Tetanus
15. Systemic aerobic infection
16. Organ transplantation.
17. Organ storage.
18. Pulmonary emphysema
19. Exceptional blood loss anemia
20. Multiple Sclerosis
21. Arthritic Diseases
22. Acute cerebral edema

As the author of the "noncovered conditions" list points out, there is no law against using HBOT for these conditions, they are merely off-label uses for HBOT. There are also articles about using HBOT for
migraine and Lyme disease (which medicare presumably won't cover either, nor, by extension, would insurance companies). And since I have a special interest in MS, I dug up this page which is the beginning of a discussion on HBOT for MS.

Why do I take this interest in HBOT? I managed to get my hands on a modest chamber and have been looking into using it therapeutically.
