Occupational Therapy Service Delivery Among Medicaid-Enrolled Children and Adults on the Autism Spectrum and With Other Intellectual Disabilities.

IMPORTANCE: Rates of occupational therapy service utilization among people with autism spectrum disorder (ASD) or intellectual disability (ID) have not been explored in population-based samples. OBJECTIVE: To describe occupational therapy services delivered to Medicaid-eligible persons younger than age 65 yr identified as having ASD, ID, or both and to evaluate demographic factors associated with occupational therapy service utilization in this population. DESIGN: Retrospective, case-control, cohort study using claims records from Medicaid Analytic eXtract files (2009-2012). SETTING: Data from all 50 states and Washington, DC. PARTICIPANTS: Beneficiaries identified as having ASD only, ASD+ID, or ID only who were younger than age 18 yr (N = 664,214) and ages 18-64 yr (N = 702,338). Outcomes and Measures: We analyzed Current Procedural Terminology® and Healthcare Common Procedure Coding System procedure codes, Medicaid Statistical Information System type of service codes, and Center for Medicare & Medicaid Services provider specialty codes. RESULTS: Only 3.7% to 6.3% of eligible adult beneficiaries received occupational therapy; in contrast, 20.5% to 24.2% of children received occupational therapy. Significant predictors of service use varied by group; however, differences by race-ethnicity, eligibility on the basis of poverty, and geographic location were observed. Among children, the most frequent billing code was for "therapeutic activities" (43%-60%); among adults, it was "community/work reintegration training" (29%-39%). CONCLUSIONS AND RELEVANCE: Billed procedure code patterns do not consistently reflect the unique occupational focus that occupational therapy providers deliver to people with developmental disabilities. Disparities in occupational therapy receipt warrant further attention to understand the social and structural factors affecting service delivery. What This Article Adds: Occupational therapy services paid for by Medicaid are used more frequently by children with ASD and ID than by adults with these diagnoses. Greater understanding of the intersectional factors that drive service delivery and disparities is needed.

States' use of Medicaid to meet the needs of autistic individuals.

OBJECTIVE: To assess the use of Medicaid programs, including waivers, to address the needs of aging autistic individuals. DATA SOURCES: We gathered data on Medicaid programs in place between 2004 and 2015 for 50 states and the District of Columbia from the Centers for Medicare and Medicaid Services website, by contacting state Medicaid administrators and advocacy groups, and by reviewing the Medicaid Analytic eXtract Waiver Crosswalk. STUDY DESIGN: This retrospective analysis classified each Medicaid program and documented state changes over time in eligibility criteria: those serving autism spectrum disorder only, autism spectrum disorder or intellectual disability, and intellectual disability only. DATA COLLECTION/EXTRACTION METHODS: We captured age and diagnosis eligibility criteria for Medicaid programs serving any of the three target groups. PRINCIPAL FINDINGS: A total of 269 Medicaid programs met our criteria and most programs (51%) were 1915(c) waivers. The number of autism-specific 1915(c) waivers grew more than fivefold during the study period, outpacing increases in waivers serving individuals with intellectual disability. CONCLUSIONS: States varied in their use of Medicaid to address the needs of the aging autism population. Further study of characteristics of states that changed their Medicaid programs, and of the health care use and outcomes associated with these changes, are needed to identify opportunities to replicate effective approaches to meeting the needs of this population.
