The Affordable Care Act, along with Medicaid expansions, offers theopportunity to redesign the nation's highly flawed mental health system.It promotes new programs and tools, such as health homes,interdisciplinary care teams, the broadening of the Medicaid Home andCommunity-Based Services option, co-location of physical health andbehavioral services, and collaborative care. Provisions of the act offerextraordinary opportunities, for instance, to insure many more people,reimburse previously unreimbursed services, integrate care using newinformation technology tools and treatment teams, confront complexchronic comorbidities, and adopt underused evidence-based interventions.The Centers for Medicare and Medicaid Services and its Center forMedicare and Medicaid Innovation should work intensively with the statesto implement these new programs and other arrangements and begin tofulfill the many unmet promises of community mental health care.(Authors)
