A major feature of the Affordable Care Act is the creation of health homes that span behavioral health and primary care. Hence, a major agenda going forward is the creation of integrated care systems that span these services. Although referral and collaboration models are available, full integration at the same site is the preferred model. This session will discuss the integration of behavioral health into primary care and the integration of primary care into behavioral health. The former approach will reach a large number of persons with behavioral health conditions, because more than 60 percent of behavioral healthcare now occurs in primary care settings. The latter approach typically will reach persons who have more severe behavioral health conditions, and who require more intensive care. Both models are likely to emerge in the ACA era.
