Description

Mental health benefits legislation regulates health insurance to increase access to mental health services, including treatment for substance use disorders. Parity, a key part of most mental health benefits legislation, stipulates that health insurance plans do not impose greater restrictions for mental health coverage than for physical health coverage (CG-Mental health).

Expected Beneficial Outcomes

Increased access to mental health services
Increased substance use disorder treatment
Improved mental health
Reduced suicide

Evidence of Effectiveness

There is strong evidence that mental health benefits legislation that includes parity requirements increases appropriate utilization of mental health services (CG-Mental health) and increases substance use disorder treatment (Friedman 2017, Wen 2013). Such legislation also increases access to care (CG-Mental health, Sipe 2015, Friedman 2017, Harwood 2017) and diagnosis of mental health conditions, and reduces suicide rates and prevalence of poor mental health (CG-Mental health). More comprehensive parity laws yield stronger effects (Sipe 2015, Wen 2013).

Mental health benefits legislation that includes parity requirements has been shown to modestly increase diagnostic and therapy visits for behavioral health care (Harwood 2017), and increase outpatient and inpatient care for patients diagnosed with substance use disorder (Friedman 2017). Such legislation may also increase access and utilization of mental health services for children with autism spectrum disorder (Stuart 2017). Legislation that removes limits on coverage of outpatient mental health visits allows visits to occur according to medical necessity rather than benefit plan specifications (Grazier 2016).

Parity laws improve financial protection for patients (CG-Mental health, Sipe 2015, Ettner 2016). Such laws appear to reduce out-of-pocket spending for bipolar disorder, major depression, and adjustment disorders (Busch 2013), families whose children have the highest cost for mental health care (Barry 2013), and mental health and substance abuse treatment for adults with severe mental illness (McConnell 2013). In some cases, however, individuals diagnosed with substance use disorder may experience a modest increase in out-of-pocket spending (Friedman 2017). Children with autism spectrum disorder (Stuart 2017) and adults with health insurance through large employers appear to experience no change in total out-of-pocket costs following parity implementation (Harwood 2017).

Overall, mental health parity requirements do not appear to significantly increase insurers' annual cost per health plan member (Jacob 2015, CG-Mental health). An Oregon-based study, however, indicates insurer spending for patients with severe mental illness increased post-parity (McConnell 2013), and studies of one of the largest managed behavioral health organizations in the US indicate cost shifting from patients to plans (Ettner 2016) of approximately $1.05 per enrollee (Harwood 2017). Parity requirements for substance use disorder services appear to cause a modest increase in health plan spending (Friedman 2017, Busch 2014).

Experts suggest an ongoing need to monitor insurer compliance with the parity requirements of the federal Mental Health Parity and Addiction Act of 2008 (MHPAEA) and other parity laws (Berry 2017).

Implementation

United States

The 2010 Affordable Care Act (ACA) named coverage of mental health and substance use treatment as one of the ten essential health benefits; all plans in the individual and small employer market must include this treatment coverage (NCSL-ACA 2017).

The federal Mental Health Parity and Addiction Equity Act of 2008 (MHPAEA) prohibits insurance plans that offer mental health services from restricting this coverage any more than coverage for physical health services; this includes the Children’s Health Insurance Program (CHIP) and Medicaid managed care organizations (MCOs) (Medicaid-MHPAEA). Plans that cover fewer than 50 employees, or do not offer mental health benefits, are exempt from this act (CMS-CCIIO-MHPAEA).

As of 2015, every state and the District of Columbia had enacted some form of mental health benefits legislation (NCSL-Mental health). Large self-funded non-federal governmental employers that self-insure are exempt from state insurance mandates (CMS-CCIIO-MHPAEA).

Wisconsin

Wisconsin requires group insurers to provide minimum mandated benefits for alcoholism and other diseases as ‘mental or nervous disorders,’ with deductibles and co-pays that are comparable to other health care coverage (NCSL-Mental health).
