The impact of Medicaid expansion on spending and utilization by older low-income Medicare beneficiaries.
This study examined indirect spillover effects of Affordable Care Act (ACA) Medicaid expansions to working-age adults on health care coverage, spending, and utilization by older low-income Medicare beneficiaries. The authors used data from the 2010-2018 Health and Retirement Study survey linked to annual Medicare beneficiary summary files. They estimated individual-level difference-in-differences models of total spending for inpatient, institutional outpatient, physician/professional provider services; inpatient stays, outpatient visits, physician visits; and Medicaid and Part A and B Medicare coverage. They also compared changes in outcomes before and after Medicaid expansion in expansion versus nonexpansion states. The sample included low-income respondents aged 69 and older with linked Medicare data, enrolled in full-year traditional Medicare, and living in the community. ACA Medicaid expansion was associated with a 9.8 percentage point increase in Medicaid coverage, a 4.4 percentage point increase in having any institutional outpatient spending, and a positive but statistically insignificant 2.4 percentage point change in Part B enrollment.

Racial and ethnic disparities in health care use and access associated with loss of Medicaid supplemental insurance eligibility above the federal poverty level.
The purpose of this study was to examine whether exceeding the income threshold for Medicaid, which causes a sudden loss of Medicaid eligibility, is related with higher racial and ethnic disparities in access to and use of care. The researchers evaluated Medicare beneficiaries with incomes 0% to 200% of FPL from the 2008 to 2018 biennial waves of the Health and Retirement Study linked to Medicare administrative data. To identify racial and ethnic disparities related with the loss of Medicaid eligibility, the researchers compared discontinuities in outcomes among Black and Hispanic beneficiaries and White beneficiaries. Analyses were conducted between January 1, 2022, and October 1, 2022. The primary outcomes were patient-reported challenges accessing care due to cost and outpatient service use, medication fills, and hospitalizations measured from Medicare administrative data. The study included 8,144 participants representing 151,282, 957 weighted person-years in the community-dwelling population of Medicare beneficiaries aged 50 years and older and incomes less than 200% of the federal poverty level (FPL). Study findings indicate that exceeding the Medicaid eligibility threshold was related with a 43.8 percentage point (pp) lower probability of Medicaid enrollment among Black and Hispanic Medicare beneficiaries and a 31.0 pp lower probability of Medicaid enrollment among White beneficiaries. Among Black and Hispanic beneficiaries, exceeding the threshold was associated with increased cost-related barriers to care, lower outpatient use, and fewer medication fills, but it was not associated with a statistically significant discontinuity in hospitalizations. Discontinuities in these outcomes were smaller or nonsignificant among White beneficiaries. Consequently, exceeding the threshold was associated with widened disparities, including greater reductions in outpatient service use and medication fills among Black and Hispanic vs White beneficiaries.

Changes in insurance coverage continuity after Affordable Care Act expansion of Medicaid eligibility for young adults with low income in Massachusetts.
The purpose of this cohort study was to describe changes in insurance coverage continuity for Medicaid enrollees who turned age 19 years before and after eligibility policy changes from the 2014 Medicaid expansion of the Patient Protection and Affordable Care Act. Between November 1, 2020, and May 12, 2022 the researchers analyzed data from the Massachusetts All-Payer Claims Database (2012 to 2016) to compare coverage for Medicaid beneficiaries turning age 19 years before and after Medicaid expansion. A total of 41,247 young adults turning age 18 to 19 years in the baseline year were included in the study. The researchers found that enrollees who turned age 19 after vs before the Medicaid eligibility expansion were less likely to have 3 or more uninsured months at18 to 19 years of age and 19 to 20 years of age and more likely to have continuous insurance coverage for 12 or more months. Differences in the likelihood of having 3 or more uninsured months decreased at 20 to 21 years of age, when both groups had access to Medicaid. The study concluded that among Medicaid enrollees entering adulthood, the expansion of Medicaid to lower-income adults through the 2014 Patient Protection and Affordable Care Act was associated with a decreased possibility of becoming uninsured.

The Affordable Care Act Medicaid expansion: a difference-in-differences study of spillover participation in SNAP.
Medicaid expansion through the Affordable Care Act increased access to insurance coverage to adults under 138% of the federal poverty level and connected individuals to SNAP (the Supplemental Nutrition Assistance Food Program – formerly the Food Stamp Program). The purpose of this study was to estimate the effect of Medicaid expansion on SNAP participation among 414,000 individuals across the U.S. The study found that there was a 2.9% increase in SNAP participation produced by Medicaid expansion among individuals living under 138% of the federal poverty level. In subgroup analyses the researchers discovered a 5% increase in households without children below 75% of the federal poverty level, and an increase in SNAP households with zero dollars in income. The study concluded that the impact of the Medicaid expansion on access to SNAP participation was the greatest in very-low-income individuals, and that the impact of Medicaid expansion reaches beyond healthcare by increasing access to other supports like food which is a social determinant of health.

Association of socioeconomic characteristics with where children receive emergency care.
This study’s objective was to characterize national associations of neighborhood income and insurance type for children with the characteristics of emergency departments (EDs) from which they receive care. The authors conducted a cross-sectional study of ED visits by children from 2014 to 2017 using the Nationwide Emergency Department Sample. Emergency department characteristics were characterized by pediatric volume category. There was a total of 107.6 million ED visits from 2014 to 2017. Children outside of the wealthiest neighborhood income quartile had lower proportions of visits to high-volume pediatric EDs and greater proportions of visits to low-volume pediatric EDs than children in the wealthiest quartile. Publicly insured children were modestly more likely to visit higher-volume pediatric EDs than privately insurance and uninsured children. This association appears to be principally driven by urban-rural differences in access to pediatric emergency care.

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.

Comparison of diabetes medications used by adults with commercial insurance vs Medicare Advantage, 2016 to 2019.
Investigators sought to compare trends in initiation of treatment with GLP-1RA, SGLT2i, and DPP-4i by older adults with type 2 diabetes insured by Medicare Advantage vs commercial health plans. They found that Medicare Advantage beneficiaries may be less likely than commercially insured beneficiaries to be treated with newer medications to lower glucose levels, with greater disparities among lower-income patients. They recommended further investigation of nonclinical factors contributing to treatment decisions and efforts to promote greater equity in diabetes management.

Cognition and take-up of the Medicare Savings Programs.
In this study, the investigators examined the association between cognition and Medicare Savings Program (MSP) enrollment among elderly Medicare beneficiaries who qualified for these programs. They also examined enrollment in the Low-Income Subsidy (LIS), a separate program that provides premium and cost-sharing assistance in Medicare Part D that Medicare beneficiaries automatically received if they are enrolled in an MSP.

Assessment of behavioral health services use among low-income Medicare beneficiaries after reductions in coinsurance fees.
This study looked at outcomes from reducing behavioral health care Medicare coinsurance from 50% to 20% from 2009 to 2013. The sample of patients looked at included some diagnosed with SMI (serious mental illness) including schizophrenia, bipolar, or major depressive disorder). Data analysis was performed on 793,275 beneficiaries with SMI in 2008 and compared them with costs in 2013. The mean adjusted out-of-pocket costs for outpatient behavioral care decreased from $132 annually to $64, but the number of visits only increased slightly. No association was found between cost-sharing reductions and changes in behavioral health care visits.

Association between Medicaid expansion, dental coverage policies for adults, and children's receipt of preventive dental services.
Researchers examined whether low-income children's use of preventive dental services is linked to variation in state Medicaid policies that affect parents' access to dental care in Medicaid. Using MEPS data along with Area Health Resources File and Medicaid adult dental coverage policies, they found no change in children's receipt of preventive dental care associated with Medicaid expansions in states that covered vs did not cover preventive dental services for adults. They concluded that factors other than parental access to dental benefits through Medicaid may be more salient determinants of preventive dental care use among low-income children.

The effect of health insurance on prescription drug use among low-income adults: evidence from recent Medicaid expansions.
This study examined how subsidized coverage affected prescription drug utilization among low-income non-elderly adults. Among other results, the investigators found that within the first 15 months of new health insurance availability, aggregate Medicaid-paid prescriptions increased 19 percent, amounting to nearly 9 new prescriptions a year, per new enrollee. They also found no evidence of reductions in uninsured or privately-insured prescriptions, suggesting that new coverage did not simply substitute for other payment sources.

The effect of primary care visits on other health care utilization: a randomized controlled trial of cash incentives offered to low income, uninsured adults in Virginia.
Investigators recruited low-income uninsured adults in Virginia to determine whether cash incentives would encourage primary care provider (PCP) visits as opposed to going to the hospital emergency room. This randomized, controlled trial determined that PCP visits did increase but no reductions in overall costs occurred there was an offset from increased outpatient utilization.

Despite coverage gains, one-third of people in small-firm low-income families were uninsured in 2014-15.
Using data from the Medical Expenditure Panel Survey, the investigators examined health insurance coverage for workers at small firms and the self-employed and found that the overall uninsurance rate for these workers and their families declined by 5 percentage points over the past decade, but one-third of those with lower incomes remained uninsured in 2014-15.

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 for adults had measurable 'welcome mat' effects on their children.
This study used data from the 2013-15 American Community Survey to provide the first national-level (analytical) estimates of welcome-mat effects on children's coverage post Affordable Care Act (ACA). It estimated that 710,000 low-income children gained coverage through these effects. The study was also the first to show a link between parents' eligibility for Medicaid and welcome-mat effects for their children under the ACA.

In low-income Latino patients, post-affordable care act insurance disparities may be reduced even more than broader national estimates: evidence from Oregon.
This study compared the insurance status of low-income patients served in 23 community health centers (CHCs) in Oregon, by race/ethnicity and language, over a period of 6 years straddling the implementation of ACA-related Medicaid expansion in 2014. It found that among previously uninsured low-income patients returning to Oregon CHCs, insurance disparities were eliminated after Medicaid expansion, especially in Spanish-speaking Latinos.

Three-year impacts of the Affordable Care Act: improved medical care and health among low-income adults.
Using survey data collected from low-income adults through the end of 2016 in three states: Kentucky, which expanded Medicaid; Arkansas, which expanded private insurance to low-income adults using the federal Marketplace; and Texas, which did not expand coverage, researchers found that by the end of 2016 the uninsurance rate in the two expansion states had dropped by more than 20 percentage points relative to the nonexpansion state.

Supporting health insurance expansion: do electronic health records have valid insurance verification and enrollment data?
The researchers sought to validate electronic health record (EHR) insurance information for low-income pediatric patients at Oregon community health centers (CHCs), compared to reimbursement data and Medicaid coverage data. They concluded that EHR coverage data for children had a high overall correspondence with Medicaid data and reimbursement data, suggesting that in some systems EHR data could be utilized to promote insurance stability in their patients.
