Medical Costs
A portion of special diet costs can qualify as a medical expense. If the diet is prescribed by doctor for medical reasons, then the excess amount of costs that you have for foods over what you would normally eat is treated as a medical expense.
Fees for alternative medicine practitioners can be medicals too, according to IRS. Things like acupuncturists, chiropractors, Christian Science practitioners. Same goes for doctor-prescribed treatment at a health institute.
Amounts aid for repairing hearing aids also qualifies. Thus flex plans can reimburse these costs if they choose to do so. This also includes the cost of batteries, if not covered by the flex plan. You just add them to medical expenses and deduct them on Schedule A to extent your medical expenses exceed 7.5% of your AGI.
