Financing and payment reform for primary health care and substance abuse treatment.

One of the most controversial areas for health care reform concerns the treatment of alcohol and other drug problems, which account for some of the most rapidly rising costs in the health care sector. There is arguably no other set of conditions that show such variation in accessibility to treatment on the basis of insurance status, present the same degree of difficulty in providing comprehensive care, or challenge as many public and professional assumptions about behavioral, social and economic determinants. The purpose of this article is to discuss some of the financing and coverage barriers to comprehensive treatment for alcohol and other drug abuse; to discuss some innovative mechanisms for providing and financing comprehensive services; and to suggest some directions for public policy to support the development of new practice models that emphasize cost-effectiveness and efficiency of care.
