You may want to review IRS Publication 502, which lists items that are not deductible. Here is the information regarding Cosmetic Surgery:
What Expenses Aren't Includible?
Following is a list of some items that you can't include in figuring your medical expense deduction. The items are listed in alphabetical order.
Cosmetic Surgery
Generally, you can't include in medical expenses the amount you pay for unnecessary cosmetic surgery. This includes any procedure that is directed at improving the patient's appearance and doesn't meaningfully promote the proper function of the body or prevent or treat illness or disease. You generally can't include in medical expen-ses the amount you pay for procedures such as face lifts, hair transplants, hair removal (electrolysis), and liposuc-tion.
You can include in medical expenses the amount you pay for cosmetic surgery if it is necessary to improve a de-formity arising from, or directly related to, a congenital ab-normality, a personal injury resulting from an accident or trauma, or a disfiguring disease.
Example. An individual undergoes surgery that re-moves a breast as part of treatment for cancer. She pays a surgeon to reconstruct the breast. The surgery to recon-struct the breast corrects a deformity directly related to the disease. The cost of the surgery is includible in her medi-cal expenses.
