Or does anyone know how much they generally cost for a basic visit?

Usually not because they are in bed with the AMA which is a medical monopoly established in 1847 for the purpose of eliminating competition in the healing arts and to raise the rates of the remaining doctors (that's what they told Congress).

Most insurance companies don't cover any form of alternative medicine, but some actually do. You'd need to call your insurance company to find out whether or not they cover anything. As for how much they cost, each place is different. You'd have to call different places that you may be interested in and get a ballpark figure.
