Service-level costing of drug abuse treatment.

This paper presents a methodology for estimating costs of delivering specific substance abuse treatment services. Data collected from 13 programs indicate that the mean cost of residential treatment is $2,773 per patient per month, and outpatient treatment costs average $636 per patient per month. Data are presented on the cost patient per month for individual treatment and nontreatment services, average number of services, cost per unit of service, and intensity of services. In addition to their application to insurance benefit cost estimation, these data illustrate the costing of best-practice adolescent treatment consistent with a Center of Substance Abuse Treatment (CSAT) Treatment Improvement Protocol. In the emerging policy environment, detailed cost estimates like these will aid the design of cost-effective treatment programs, and serve the development of the substance abuse benefit in a health care reform insurance package.
