A program mandated by law as part of the Medicaid program. The law requires that all states have in effect a program for eligible children under age 21 to ascertain their physical or mental defects and to provide such health care treatments and other measures to correct or ameliorate defects and chronic conditions discovered. The state programs also have active outreach components to inform eligible persons of the benefits available to them, to provide screening, and if necessary, to assist in obtaining appropriate treatment.
