Medicaid is the largest payer of long-term services and supports (LTSS), which includes care in nursing facilities and for home and community-based services (HCBS) like adult day programs and home health aides. While care in institutional settings is a mandatory Medicaid benefit, coverage of HCBS is most commonly offered through mechanisms that are optional for states. Specifically, section 1915(c) waivers allow states to waive certain Medicaid requirements to offer HCBS to targeted populations as an alternative to institutional care and are the primary mechanism through which HCBS are delivered in Medicaid. Most HCBS are offered through these or other types of waivers rather than required through a Medicaid State Plan.
Over the past four decades, states have made intentional efforts to rebalance or shift LTSS away from institutions and toward HCBS, which is the preferred setting for care for most eligible individuals. The Centers for Medicare and Medicaid Services reports that 9.7 million people nationwide rely on Medicaid‑funded LTSS, the vast majority (87%, or 8.4 million people) of whom received HCBS. In 1981, HCBS accounted for just 1 percent of all national Medicaid LTSS spending. By 2023 that share had grown to nearly 64 percent. This transformation reflects a sustained commitment to person-centered care and the use of creative policy tools — particularly section 1915(c) waivers — to meet the needs of diverse populations, from older adults and people with physical disabilities to individuals with autism, brain injuries, and HIV/AIDS.
Landscape Analysis of HCBS Waivers
NORC at the University of Chicago conducted a comprehensive review of the national HCBS waiver landscape, analyzing 262 active section 1915(c) waivers across 46 states and the District of Columbia with the goal of identifying how these services vary across states and populations. In addition, NORC conducted case studies of Colorado and Florida, which have taken different paths but have both been successful in expanding access to HCBS. We explored states’ successes in increasing access to HCBS and sought to uncover disparities in access — particularly in rural areas — and highlight populations that may be excluded or underserved.
