That's an excellent question.
It's been studied in a number of different scenarios. One was in Tennessee where they looked at total health care costs because the costs were contained within an HMO. An HMO pays for everything. When you belong to an HMO they are responsible for covering all your costs, similar to the Canadian military. When you're a member of the military, your costs are contained within the military.
When you look at the cost of including complementary or alternative medicine, that is, when the member was taking part in conservative alternative medicine, chiropractic being 80% of that in terms of the dollar value, in an average claim year, instead of $2,700, they were able to reduce it to $2,200. If you were receiving chiropractic care you were costing the HMO less money.
