Which medical expenses aren't tax deductible?
Any medical expenses you get reimbursed for, such as by your insurance or employer, can't be deducted. In addition, the IRS generally disallows expenses for cosmetic procedures. You typically can't deduct the cost of nonprescription drugs (except insulin) or other purchases for general health, such as toothpaste, health club dues, vitamins, diet food and nonprescription nicotine products. You also can't deduct medical expenses paid in a different year.
