Drawing from utilization data for fiscal year 1986 and prior years of the Civilian Health and Medical Program of the Uniformed Services, the single largest health plan in the country, we see continued growth in the number of practitioners providing mental health services and a continuing penetration into the health care market by psychologists though with wide variation among states. While the range of mental health procedures which can be provided is substantial, hourly individual psychotherapy is the predominant procedure accounting for almost three quarters of all outpatient visits and over half the inpatient visits. In several respects this major federal plan provides a current perspective on fee-for-service patterns of practice.The Civilian Health and Medical Program of the Uniformed Services (CHAMPUS) is the single largest health plan in the nation. As a militaryrelated benefit, comprehensive health care is available to dependents of active-duty personnel and to retired military and their dependents or survivors. In 1986 there were 6.295 million persons eligible for CHAMPUS benefits, not many fewer than the 6.324 million eligible in 1981. Recognition for clinical psychologists under the CHAMPUS The cooperation of CHAMPUS in supplying the fiscal year data and particularly of Mr. Rich Barnett, Chief of Statistics, for helpful personal clarification is very much appreciated and made this article possible.
