A child whose disability restricts his or her diet shall be provided food substitutions only when supported by a statement signed by a licensed physician. The supporting statement shall identify: the individual's disability and an explanation of why the disability restricts the child's diet; the major life activity affected by the disability; and the food or foods to be omitted from the child's diet and the food or choice of foods that must be substituted. Such meals or snacks shall be claimed at the same reimbursement rate as meals/snacks which meet the meal pattern. The services of a registered dietitian should be utilized to assist in implementing the physician's prescription.
