Behavioral health benefits have long been subject to greater restrictions than other health benefits. However, the gap between behavioral and other health benefits widened during the 1980s and 1990s as health plans and purchasers sought to contain rising costs. The Mental Health Parity Amendment (P.L. 104—204), which took effect in 1998, sought to redress these inequities by requiring companies with 50 or more workers to set the same annual and lifetime spending limits for mental health care as for other health benefits. This column provides a snapshot of mental health coverage across two different types of health plans, health maintenance organizations (HMOs) and indemnity insurance plans, in 1997, immediately before enactment of the parity law.
