Is food eligible reimbursement under any circumstance?

Food is typically not eligible for reimbursement. However, there are limited circumstances in which the excess cost of a special food over a product that satisfies normal nutritional needs may be eligible with a Letter of Medical Necessity (LMN): (1) the food or beverage doesn't satisfy normal nutritional needs, (2) the food or beverage alleviates or treats an illness, and (3) the need for the food or beverage is substantiated by a physician. The medical expense is limited to the amount by which the cost of the food or beverage exceeds the cost of a product that satisfies normal nutritional needs.
