In states that mandate coverage for autism spectrum disorder (ASD) health services, families in high-deductible health plans (HDHPs) access ASD-related services without paying more out-of-pocket expenses than traditional plan enrollees, an analysis found.

Lead author Colleen L. Barry, PhD, of Johns Hopkins University, Baltimore, and colleagues examined insurance claims between 2008 and 2012 for children covered by three large U.S. insurers (United Healthcare, Aetna, and Humana) to compare the effects of ASD-related coverage mandates on health spending. At least 47 states and Washington, D.C., have enacted mandates that require insurers to cover ASD-related health services, such as diagnostic and assessment services and behavioral and functional therapies. The final study sample included 98,639 children aged 0-21 years with at least two ASD-related service claims on different days during the study period.
The investigators found that, among HDHP enrollees, coverage mandates were associated with marked increases in average monthly spending across all service categories, but not among traditional plan enrollees. Specifically for HDHP patients, ASD coverage mandates were linked to a $98 greater increase in average monthly spending for insurers on ASD-specific outpatient services, a $142 greater increase in average monthly insurer spending on all outpatient services, and a $142 greater increase in average monthly insurer spending on all health services, according to the study published in Pediatrics. Out-of-pocket spending by patients however, was not significantly different between HDHP and traditional plan enrollees in states that mandate ASD-related coverage, the study found.
Dr. Barry and associates concluded that patients in both HDHP and traditional insurance plans spend large sums on ASD-related care in coverage mandate states, but because costs likely exceed HDHP deductibles, insurers absorb any increases. They suggested that families with regularly high health care expenditures related to ASD services consider high-deductible plans in the context of mandate laws.
“Future research is needed to better understand how features of HDHPs, such as deductible size and health savings account structure, influence the ability of families to make wise choices in obtaining care, and to examine plan premiums and financial strain associated with these plans, particularly for families with children with ASD and high expenditures,” Dr. Barry and associates wrote.
