If the medical record of any child at any time discloses a condition which requires medical, dental or surgical treatment and the parent or guardian states to the school authorities that he is financially unable to have a physician or dentist of his choice render such care, he shall be advised that the cost of such care may be provided if application is made to the appropriate county board of public assistance. Upon application, the county board of assistance shall authorize payment for necessary medical, dental or surgical care as assistance is defined in the standards, rules and regulations established by the Secretary of Public Welfare¹ in consultation with the Secretary of Health. If it appears that the parent or guardian was financially able to pay for the medical, dental or surgical care for which payment was made on the authorization of a county board of assistance, the Department of Public Welfare shall recover the amounts thus expended from the parent or guardian liable for the support of such child as provided in the support law.
