Private employers and state Medicaid programs are increasingly writing
risk contracts with managed behavioral health care companies to manag
e mental health and substance abuse benefits. This paper analyzes the
case for a carve out program and makes recommendations about the form
of the payer managed behavioral health care contract. Payers should co
nsider using a ''soft'' capitation contract in which only some of the
claims' risk is transferred to the managed behavioral health care comp
any. To avoid incentives to underserve seriously ill persons, we recom
mend that payers not allow choice by enrollees among risk contractors.
