Public insurance expansions and mental health care availability.

ABSTRACT:

Objective

To provide new evidence on the effects of large-scale public health insurance expansions, associated with the Affordable Care Act (ACA), on the availability of specialty mental health care treatment in the United States. We measure availability with the probability that a provider accepts Medicaid.

Data source/study setting

The National Mental Health Services Survey (N-MHSS) 2010-2018.

Study design

A quasi-experimental differences-in-differences design using observational data.

Data collection

The N-MHSS provides administrative data on the universe of specialty mental health care providers in the United States. Response rates are above 90 percent in all years. Data cover 85 019 provider/year observations.

Principal findings

ACA-Medicaid expansion increases the probability that a provider accepts Medicaid by 1.69 percentage points, 95 percent confidence interval: [0.0017,0.0321], which corresponds to an increase from 87.27 percent pre-expansion to 90.27 percent postexpansion in expansion states or a 1.94 percent increase. We observe spillovers to Medicare, although this finding is sensitive to specification.

Conclusions

This study provides evidence on the impact of ACA-Medicaid expansion on accepted forms of payment for specialty mental health care treatment. Findings suggest that expansion increases availability of providers who deliver valuable care for enrollees with severe mental illness. These findings may help policy makers reflecting on the future directions of the US health care delivery system.

Project description:ImportanceMany US children and adolescents with mental and behavioral health (MBH) conditions do not access MBH services. One contributing factor is limited insurance coverage, which is influenced by state MBH insurance parity legislation.ObjectiveTo investigate the association of patient-level factors and the comprehensiveness of state MBH insurance legislation with perceived poor access to MBH care and perceived inadequate MBH insurance coverage for US children and adolescents.Design, setting, and participantsThis retrospective cross-sectional study was conducted using responses by caregivers of children and adolescents aged 6 to 17 years with MBH conditions in the National Survey of Children's Health and State Mental Health Insurance Laws Dataset from 2016 to 2019. Data analyses were conducted from May 2022 to January 2024.ExposureMBH insurance legislation comprehensiveness defined by State Mental Health Insurance Laws Dataset (SMHILD) scores (range, 0-7).Main outcomes and measuresPerceived poor access to MBH care and perceived inadequacy of MBH insurance were assessed. Multivariable regression models adjusted for individual-level characteristics.ResultsThere were 29 876 caregivers of children and adolescents with MBH conditions during the study period representing 14 292 300 youths nationally (7 816 727 aged 12-17 years [54.7%]; 8 455 171 male [59.2%]; 292 543 Asian [2.0%], 2 076 442 Black [14.5%], and 9 942 088 White [69.6%%]; 3 202 525 Hispanic [22.4%]). A total of 3193 caregivers representing 1 770 492 children and adolescents (12.4%) perceived poor access to MBH care, and 3517 caregivers representing 1 643 260 of 13 175 295 children and adolescents (12.5%) perceived inadequate MBH insurance coverage. In multivariable models, there were higher odds of perceived poor access to MBH care among caregivers of Black (adjusted odds ratio [aOR], 1.35; 95% CI, 1.04-1.75) and Asian (aOR, 1.69; 95% CI, 1.01-2.84) compared with White children and adolescents. As exposures to adverse childhood experiences (ACEs) increased, the odds of perceived poor access to MBH care increased (aORs ranged from 1.68; 95%, CI 1.32-2.13 for 1 ACE to 4.28; 95% CI, 3.17-5.77 for ≥4 ACEs compared with no ACEs). Compared with living in states with the least comprehensive MBH insurance legislation (SMHILD score, 0-2), living in states with the most comprehensive legislation (SMHILD score, 5-7) was associated with lower odds of perceived poor access to MBH care (aOR, 0.79; 95% CI, 0.63-0.99), while living in states with moderately comprehensive legislation (score, 4) was associated with higher odds of perceived inadequate MBH insurance coverage (aOR, 1.23; 95% CI, 1.01-1.49).Conclusions and relevanceIn this study, living in states with the most comprehensive MBH insurance legislation was associated with lower odds of perceived poor access to MBH care among caregivers for children and adolescents with MBH conditions. This finding suggests that advocacy for comprehensive mental health parity legislation may promote improved child and adolescent access to MBH services.
