Here's what I found on the IRS laws, I only took bits and peices so you might want to visit the website yourself and read everything on the specific law. The two different accountants I have had in the last 4 years have said it is a legal deductiona and all we need to do is make sure we save all of our reciepts.
Section 213(a) of the Internal Revenue Code of 1986, as amended, states in relevant part:
“(a) Allowance of Deduction-There shall be allowed as a deduction of the following amounts, not compensated for by insurance or otherwise-
(1) The amount by which the during the taxable year…for medical care of the taxpayer, his spouse, and dependents…exceeds 7 ½ percent of the adjusted gross income…”
Section 213 (d)(1)(A) defines “medical care” as “amounts paid for the diagnosis, cure, mitigation, treatment, or prevention of disease, or for the purpose of affecting any structure or function of the body.”
