State mental health policy: Back to the future: New Mexico returns to the early days of Medicaid managed care.

Gubernatorial administrations in New Mexico have initiated four overhauls of the publicly funded behavioral health care system over the past two decades. The most recent effort, Centennial Care, was implemented under a Section 1115 Medicaid waiver in January 2014. The authors describe Centennial Care, which closely resembles the now defunct restructuring of the public system that introduced Medicaid managed behavioral health care to the state in 1997. They also note disruptions in services to clients and hardships for providers, described locally as a "behavioral health crisis," that resulted from actions taken in 2013 by the current gubernatorial administration to force the takeover of 15 nonprofit service delivery agencies by five Arizona companies. These actions led to an onsite investigation by the Centers for Medicare and Medicaid Services.
