Florida, like many other states, has embarked on an experiment with managed
mental health care for Medicaid enrollees. Under a 1915 (b) waiver the sta
te's Medicaid agency began a mental health carve-out demonstration in March
1996 in the Tampa Bay area. This qualitative case study seeks to ascertain
the impact of the carve-out (and, by comparison, HMO arrangements) an the
public mental health sector Findings suggest that the carve-out demonstrati
on has succeeded in creating a fully integrated mental health delivery syst
em with financial and administrative mechanisms that support a shared clini
cal model; However; other findings raise concerns about the HMO model in te
rms of stability access to care, efficiency and more generally about the sh
ifting of risk and public responsibility "downstream" to private organizati
ons without sufficient governmental oversight. These findings may offer gui
dance for other states implementing major managed care policy initiatives f
or disabled Medicaid enrollees.
