Many managed care plans may need to modify their coverage to address s
ubstance abusers' multidimensional physical, mental, and social proble
ms. Such adjustments are particularly important for public sector clie
nts whose addiction-related problems are typically more severe than th
ose of private sector patients. Data from a sample of 161 medical emer
gency, primary care, mental health, and substance abuse treatment prog
rams in Dade County, Florida, reveal highly varied perceptions of mana
ged care. They illustrate that the relevance of provider organization
ownership, type of services, and populations served for behavioral man
aged care analysis. Further implications are the need to provide ''wra
p-around'' or enabling services and to coordinate care for substance a
busers to avoid displacement of responsibility for critical aspects of
their care onto overwhelmed ''safety net'' agencies.
