A bipartisan group of U.S. senators sent a letter to the Government Accountability Office requesting a report on Medicaid oversight and quality of care in assisted living facilities, according to Sen. Elizabeth Warren (D-MA).

Many states cover assisted living services through Medicaid home and service waivers, and others cover services through state plans or Medicaid comprehensive demonstration waivers. Although the federal government oversees some of the care through the Medicaid and Medicare program, the care has been mostly overseen by states.

The GAO should ascertain number of Medicaid enrollees in assisted living facilities and the amount of Medicaid spending for relate care, while also investigating the payment levels and eligibility requirements for state Medicaid coverage, the senators wrote. Additionally, they asked the GAO to find out how the state Medicaid programs oversee assisted living care and how it differs from care provided to Medicaid-covered residents in nursing facilities.

“Given the growth in federal Medicaid spending for long-term care services and expected program growth caused by the aging and expansion of the population and program, information to understand federal and state spending and oversight of care provided in these settings is needed,” the senators wrote.
