Variations in HCBS Spending, Use, and Hospitalizations among Medicaid 1915(c) Waiver Enrollees

The relationship between Medicaid policy and realized access to home- and community-based services

Medicaid funding for home- and community-based services (HCBS) has increased substantially in recent decades. Prior research has investigated the effects of this expansion on outcomes for individuals as well as costs to Medicaid, often using state policy as a proxy for access to HCBS or implicitly assuming that more generous policies affect outcomes through access, an assumption that may not hold. In this study, using survey data linked to Medicaid claims, we assess the extent to which common measures of state Medicaid HCBS generosity correspond to increased individual use of HCBS among older adults with potential needs. We find several measures to have strong predictive power, but only with relatively large changes in policy generosity. Our findings imply that increased funding of HCBS is not sufficient to ensure access to services and that researchers should be careful when using state policy generosity as a proxy for access.

Trends In Medicaid Home And Community-Based Services Waivers For Older Adults

During the past several decades, state Medicaid programs have expanded the use of home and community-based services, particularly through Section 1915(c) waivers and Section 1115 demonstration waivers. We document trends from the period 1997-2020 in waivers targeting older adults, focusing on services offered. Nearly every service category saw an increase in coverage and spending, especially support for self-direction and community transition.

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.
