does insurance cover it? Cause I'm guessing that if insurance would cover it, it probably counts for taxes. (general rule of thumb, and I'm not a tax expert, ymmv)
Side note - it only really matters if your medical expenses are high enough to deduct, and there's a 7.5% (check that...) of AGI threshold you have to meet first. Plus, you have to itemize deductions. It's a pretty big hurdle honestly. Since you're asking, I'm assuming that you've cleared those amounts, but just in case you haven't, don't give yourself a headache.
