The IRS defines medical expenses as "the costs of diagnosis, cure, mitigation, treatment, or prevention of disease, and for the purpose of affecting any part or function of the body. These expenses include payments for legal medical services rendered by physicians, surgeons, dentists, and other medical practitioners. They include the costs of equipment, supplies, and diagnostic devices needed for these purposes.
Medical care expenses must be primarily to alleviate or prevent a physical or mental disability or illness. They don't include expenses that are merely beneficial to general health, such as vitamins or a vacation.
Medical expenses include the premiums you pay for insurance that covers the expenses of medical care, and the amounts you pay for transportation to get medical care. Medical expenses also include amounts paid for qualified long-term care services and limited amounts paid for any qualified long-term care insurance contract."
IRS publication 502 will help you identify which medical expenses can and cannot be used on your tax return. Simply click on the expense category you would like to know more about and it will give you a brief overview.
