National Estimates of Mental Health Insurance Benefits.

This article presents estimates of the proportion of the U.S. population that had mental health benefits in 1999, the extent of their coverage, and the proportion enrolled in health plans subject to the Mental Health Parity Act of 1996 (MHPA). Over three-quarters (76 percent) had mental health benefits as part of their health insurance. Approximately 18 percent had no such benefits; for the remaining 6 percent, mental health benefits could not be determined. Of the 18 percent with no mental health benefits, 84 percent also had no health insurance; the remainder (16 percent) had health insurance that did not cover mental health benefits. Estimates of the generosity of coverage indicate that for 44 percent of the population, benefits included prescription drugs as well as at least 30 inpatient days and 20 outpatient visits for psychiatric care. For 12 percent of the population, benefit generosity could not be determined. Finally, study results suggest that the MHPA affected only 42 percent of the U.S. population.
