(2) The department, in accordance with rules established by it, shall either charge, assess, or collect, or cause to be charged, assessed, or collected, fees for any service it provides to its clients either directly or through its agencies or contractors, except for:
(a) Diagnosis and evaluation procedures necessary to determine the client's eligibility and need for services provided by the department;
(b) Customary and routine information and referral services;
(c) Educational services provided in lieu of public education;
(d) Specific services exempted by law from fee assessment;
(e) Emergency shelter or emergency detention care and custody prior to a detention hearing under chapter 39;
(f) Specific classes or types of services provided in programs funded by grants, donations, or contracts that prohibit charging fees;
(g) Developmental disability services provided under chapter 393 to any person who is determined to be eligible for such services and whose earned income falls below the federal Health and Human Services Poverty Guidelines, unless such fees are collected from third-party benefits and benefit payments; or
(h) Any type of service for which the department determines that the net estimated revenue from such fees after deducting any loss of funds from federal grants occasioned by such fees will be less than the estimated cost to charge and collect such fees.
Fees, other than third-party benefits and benefit payments, may not be charged for services provided to indigents whose only sources of income are from state and federal aid. In addition, fees may not be charged parents of a minor client for services requested by the minor without parental consent or for services provided a minor client who has been permanently committed to the care and custody of the department with parental rights permanently severed. However, lack of parental consent does not preclude the charging of fees established under chapter 39. A client who is receiving wages that are below the minimum wage under the federal Fair Labor Standards Act may not be required to pay fees from such wages. Voluntary payments for services must be encouraged.
