"Alternative medicine" and health insurance in the US.

A couple questions regarding this:

1) How much a year do health insurance companies pay out for “alternative medicine” like acupuncture, chiropractic, or homepathic services?* (For example, Medicare neither pays nor reimburse for 2 of the three of thoses <cite 1> <cite 2> <cite 3>
Whereas UHC, the US’ largest private health care company, does cover Chiropractic care, and while some sites say no, here’s one that says yes but is “Limited to 12 visits per year”. And here is an acupuncturist who says:

2) Would eliminating these coverages significantly reduce health care premiums? (Let’s define significantly as anything over 10%).

3) Are there laws nationwide or state-based which require these insurers to cover “alternative medicine”?

*Using quotes to denote the specific term of “alternative medicine”, but I’ll also admit to my bias against the practices.

I’ll tackle this one for now.

My impression is that on a national basis, coverage for alt med is currently limited enough that savings would not be that substantial.

Given that the eternal dream of [del]quacks[/del] alternative practitioners is to have their offerings covered by insurance/Medicare, the real concern is that coverage will be greatly expanded. In that event, not only chiropractic and acupuncture for limited conditions would be covered, but insurance would pay for therapeutic touch, naturopathy (including homeopathic drugs and similar woo), crystal healing, craniosacral manipulation and a gazillion other treatments. In that case, premiums likely would jump significantly.
