“Handicapped child,” as used in this article, means a physically defective or handicapped person under the age of 21 years who is in need of services. The director shall establish those conditions coming within a definition of “handicapped child” except as the Legislature may otherwise include in the definition. Phenylketonuria, hyaline membrane disease, cystic fibrosis, and hemophilia shall be among these conditions.
The reference to “the age of 21 years” in this section is unaffected by Section 1 of Chapter 1748 of the Statutes of 1971 or any other provision of that chapter.
