The number of Americans needing long-term services and supports (LTSS) is projected to more than double in the coming decades, from 12 to 27 million by 2050, largely due to an aging baby boomer population and the prevalence of disability increasing with age (The SCAN Foundation, 2012). With longer life spans, higher rates of chronic conditions, fewer family caregivers, and increasingly limited federal, state, and family resources, paying for LTSS will become an even greater challenge for American families and our country (Federal Commission on Long-Term Care, 2013). Medicaid is currently the primary funder of LTSS in the United States, financing approximately 62% of all LTSS costs (National Health Policy Forum, 2014). However, the Medicaid program requires older adults and people with disabilities to impoverish themselves. Moreover, there remains a long-standing institutional bias within the Medicaid program, where services in nursing facilities are mandatory while home-and community-based services (HCBS) are mostly optional for states to cover. For these reasons, the aim of this study was to explore Medicaid HCBS 1915(c) waivers for older adults. Significant progress has been made over the past two decades in shifting the balance from institutional services to HCBS within states. In 1995, only approximately 18% of national Medicaid LTSS spending was devoted to HCBS (Eiken, Srel, Burwell, & Woodward, 2017). By 2015 (the most recent year for which data is available), HCBS accounted for 55% of total national Medicaid LTSS spending. However, despite overall national progress, significant variations remain across states and different populations receiving services. For example, while HCBS accounted for 75% of total Medicaid LTSS spending for individuals with intellectual and developmental disabilities (IDDs), HCBS only accounted for 44% of total Medicaid LTSS spending for older individuals and individuals with physical disabilities. Seven states spend 20% or less of their LTSS expenditures for older adults and individuals with physical disabilities on HCBS. States have numerous authorities and a great deal of flexibility in how they design Medicaid HCBS program. Three primary authorities that states have used are as follows: (a) mandatory home health services state plan benefit, (b) optional state plan amendments (i.e., personal care 788889D PSXXX10.
