Increasing Medicaid's stagnant asset test for people eligible for Medicare and Medicaid will help vulnerable seniors.
Researchers examined states' income and asset tests for full-benefit Medicaid during the period 2006-18 and examined how alternative asset tests would affect eligibility for community-dwelling Medicare beneficiaries ages sixty-five and older. They found that increasing asset limits would lessen restrictions on Medicaid eligibility that arise from stagnant asset tests, broadening eligibility for certain low-income Medicare beneficiaries and allowing them to retain higher, yet still modest, savings.

Welcome mats and on-ramps for older adults: the impact of the Affordable Care Act's Medicaid Expansions on Dual Enrollment in Medicare and Medicaid.
The authors examined whether Medicaid participation by low-income adults age 65 and up increased as a result of Medicaid expansions to working-age adults under the Affordable Care Act (ACA). Using American Community Survey data and state variation in ACA Medicaid expansions, they found that Medicaid expansions to working-age adults increased Medicaid participation among low-income older adults by 4.4 percent. They also found evidence of an “on-ramp” effect, which is an important mechanism behind welcome mat effects among some older adults.

The relationship between take-up of prescription drug subsidies and Medicaid among low-income Medicare beneficiaries.
In this study, the investigators examined take-up of the Low-Income Subsidy (LIS) and Medicaid among Medicare beneficiaries who qualified for both programs. They went beyond prior analyses that reported average enrollment by program by 1.) examining whether LIS take-up mirrored Medicaid enrollment at income levels where individuals qualified for limited Medicaid benefits that had low take-up rates and 2.) highlighting opportunities for policy reforms to increase participation in both programs.

Insurance coverage for non-standard workers: experiences of temporary workers, freelancers, and part-time workers in the USA, 2010-2017.
This AHRQ-authored paper estimates insurance disparities across non-standard employment categories and determines how coverage disparities shifted following health reform in 2014. Data on working-age adults was analyzed from the 2010-2012 and 2015-2017 MEPS. Uninsurance decreased after health reform for all groups of nonstandard workers with a 10-14% point decline. Uninsurance remained high for all freelance workers at 30.8%, full-time temporary workers (25.1%) and part-time workers (17.9%) compared to full-time workers (11.9%). Lower uninsurance in a Medicaid expansion state was found for all categories of workers.

Does Medicaid coverage of Medicare cost sharing affect physician care for dual-eligible Medicare beneficiaries?
The objective of this paper was to assess changes in physicians' provision of care to duals (low-income individuals with Medicare and Medicaid) in response to a policy that required Medicaid to fully pay Medicare's cost sharing for office visits with these patients. This policy-a provision of the Affordable Care Act-effectively increased payments for office visits with duals by 0%-20%, depending on the state, in 2013 and 2014.

Modernizing Medicaid coverage for Medicare beneficiaries with low income.
Medicaid serves as a supplemental insurer for eleven million low-income Medicare beneficiaries, known as duals. For these beneficiaries, Medicaid pays for Medicare’s out-of-pocket costs, including premiums, deductibles and coinsurance. This paper examined opportunities to close these gaps in Medicaid coverage and discussed how these reforms could complement other efforts to modernize Medicaid for low-income Medicare beneficiaries.

Medicaid coverage 'cliff' increases expenses and decreases care for near-poor Medicare beneficiaries.
Cost sharing in traditional Medicare can consume a substantial portion of the income of beneficiaries who do not have supplemental insurance, resulting in a supplemental coverage cliff. The authors estimated that Medicaid beneficiaries affected by this cliff incurred an additional $2,288 in out-of-pocket spending over the course of two years, used 55 percent fewer outpatient evaluation and management services per year, and filled fewer prescriptions. They recommended expanding eligibility for Medicaid supplemental coverage and increasing take-up of Part D subsidies to lessen cost-related barriers to health care among near-poor Medicare beneficiaries.

Medicaid expansion and marketplace eligibility both increased coverage, with trade-offs in access, affordability.
The researchers found that as of 2015, adults with incomes of 100-138 percent of the federal poverty level had experienced large declines in uninsurance rates in both expansion and nonexpansion states. Adults in expansion and nonexpansion states also experienced similar increases in having a usual source of care and primary care visits, and similar reductions in delayed receipt of medical care due to cost.

Medicaid expansion coverage effects grew in 2015 with continued improvements in coverage quality.
The researchers used detailed federal survey data through 2015 to analyze recent changes in coverage for low-income adults after the expansion associated with the Affordable Care Act's (ACA's) Medicaid expansion in 2014. They found that the uninsurance rate fell in both expansion and nonexpansion states but that it fell significantly more in expansion states.
