The Treatment Intervention Advisory Committee (TIAC) was formed early in 2011 to support the Department of Health Services (DHS) in ensuring quality services are available to the citizens of Wisconsin.

Under DHS 107.035, the department is charged with determining whether a Medicaid-covered service (including services under home and community-based waiver programs) is experimental in nature. One means by which DHS makes these determinations is through the judgment of a committee of experts with demonstrated research proficiency that is established by DHS to perform health care services review.

The Treatment Intervention Advisory Committee works to advise the department relative to the quantity and quality of evidence supporting non-medical treatment interventions for individuals with autism and other developmental disabilities. Typically these interventions fall in the area of behavioral health, though may occasionally cross boundaries into other health areas.
