Tobacco surcharges associated with reduced ACA marketplace enrollment.
Researchers used 2014-19 administrative data on enrollees in the federally facilitated Affordable Care Act Marketplace, HealthCare.gov, to examine the relationships among surcharge rates, total Marketplace enrollment, and enrollment by tobacco users. They found that the tobacco surcharge rate was associated with lower total enrollment as well as a reduced share of total enrollees who reported any tobacco use. Further, tobacco surcharges have a significantly larger effect on tobacco users' share of enrollment in rural areas than in urban areas, which may contribute to urban-rural health disparities.

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.

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.

Hospitalization rates among persons with HIV who gained Medicaid or private insurance after the Affordable Care Act in 2014.
The purpose of this study was to investigate whether gaining inpatient healthcare coverage had an effect on hospitalization rates among persons with HIV following implementation of the Affordable Care Act in 2014. Hospitalization data from 2015 were obtained on adults receiving longitudinal care at HIV clinics; all patients were previously uninsured and supported by the Ryan White HIV/AIDS Program (RWHAP) in 2013. Findings showed that acquiring inpatient coverage was not associated with a change in hospitalization rates.

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.

Regulation of provider networks in response to COVID-19.
The authors anticipate that the coronavirus disease 2019 pandemic will have 3 main effects on provider networks and their regulation: enrollment changes, changes to the provider landscape, and changes to care delivery. They suggested that telehealth will have a larger role in care delivery than in the pre-pandemic period, and that regulators will need to adapt network standards to accommodate in-person and virtual care delivery.

The effects of coding intensity in Medicare Advantage on plan benefits and finances.
The authors assessed how beneficiary premiums, expected out-of-pocket costs, and plan finances in the Medicare Advantage (MA) market are related to coding intensity. The study sample included beneficiaries enrolled in both MA and Part D from 2008-2015; Medicare claims and drug utilization data for Traditional Medicare beneficiaries were used to calibrate an independent measure of health risk. The authors found that, while coding intensity increased taxpayers' costs of the MA program, enrollees and plans both benefitted but with larger gains for plans. They concluded that the adoption of policies to adjust more completely for coding intensity would likely affect both beneficiaries and plan profits.

Estimating heterogeneous effects of a policy intervention across organizations when organization affiliation is missing for the control group: application to the evaluation of accountable care organizations.
This study looked at the effects of accountable care organizations (ACOs) on lowering health care costs and reducing the rate of hospital readmissions. The authors used Medicare fee-for-service claims data from 2009-2014 to estimate the heterogenous effects of Medicare ACO programs on hospital admissions across hospital referral regions and provider groups. The results suggested that the ACO programs reduced the rate of readmission to hospitals, and that the effect of joining an ACO varied considerably across medical groups.

Assessment of the Patient Protection and Affordable Care Act's increase in fees for primary care and access to care for dual-eligible beneficiaries.
The purpose of this study was to examine the association between the Affordable Care Act (ACA) fee bump and primary care visits for dual-eligible Medicare and Medicaid beneficiaries. Medicare claims data from 2012 to 2016 was used. Findings showed that the ACA fee bump was not associated with increases in primary care visits for dual-eligible Medicare and Medicaid beneficiaries. Additionally, visits for dual-eligible beneficiaries with primary care physicians decreased after the ACA, a decrease that was partially offset by increases in visits with nonphysician clinicians.

Impacts of the Affordable Care Act on receipt of women's preventive services in Community Health Centers in Medicaid expansion and nonexpansion states.
Researchers assessed whether ACA implementation and Medicaid expansion were followed by greater receipt of recommended preventive services among women and girls in a large network of community health centers. Data was collected from electronic health records in 14 states. The researchers found that among female patients at community health centers, receipt of recommended preventive care improved after ACA implementation in both Medicaid expansion and non-expansion states, although the overall rates remained low. They recommended continued support to overcome barriers to preventive care in this population.

Integrating fundamental cause theory and Bourdieu to explain pathways between socioeconomic status and health: the case of health insurance denials for genetic testing.
This paper proposes that Pierre Bourdieu's theories of capital and symbolic power can be integrated with fundamental cause theory to address limitations in the latter theory, making it more useful in health disparities research. This work deepens appreciation for the durable relationship between socioeconomic status and health. Study results reveal the multiple and complex mechanisms that play a role in access to healthcare services, which has significant implications for how we think about the role of health policy in addressing health disparities.

Carve-out plan financial requirements associated with national behavioral health parity.
The authors examined changes in carve-out financial requirements following the Mental Health Parity and Addiction Equity Act (MHPAEA). They found that the MHPAEA was associated with increased generosity in most observed financial requirements, but increased use of deductibles may have reduced generosity for some patients.

Hospitals strengthened relationships with close partners after joining accountable care organizations.
This study tested the hypothesis that hospitals participating in Medicare Accountable Care Organizations (ACOs) try to influence where their patients receive care in order to achieve quality and cost containment goals. The authors studied hospitals participating in ACO from 2010 to 2014. ACO hospitals shared patients 4.4% more than non-ACO hospitals. This occurred disproportionately at hospitals that already shared a high proportion of their patients prior to participation and among hospitals in ACOs characterized as physician-hospital collaborations.

Private/marketplace insurance in community health centers 5 years post-affordable care act in Medicaid expansion and non-expansion states.
This study compared differences in private/marketplace insurance in community health centers (CHCs) 5 years post-Affordable Care Act (ACA) in Medicaid expansion and non-expansion states. Electronic health record data from 702,663 patients in clinics across 20 states was used to explore trends in private/market insurance post-expansion and whether CHC patients retain private/marketplace insurance. The authors found that patients in non-expansion state CHCs relied more heavily on private/marketplace insurance than patients in expansive states and had increased visits from 2014 through 2018. There was a more pronounced seasonal variation in private/marketplace-insured visits too. A greater percentage of those who in non-expansion states did not retain private/marketplace insurance become uninsured, while those in expansion states gained other types of health insurance.

The role of marketplace policy on welcome mat effects for children eligible for Medicaid or the Children's Health Insurance Program.
This study examined the role of marketplace policy on “welcome mat” effects for children eligible for Medicaid or the Children’s Health Insurance Program (CHIP). Data from the American Community Survey from 2013-2018 was used to estimate the relationship between Marketplace policy and increases in Medicaid/CHIP coverage among pre-ACA eligible children after the implementation of the Affordable Care Act (ACA). The sample included non-disabled citizen children ages 0-18 at 139-250% federal poverty level who were Medicaid/CHIP-eligible before and after implementation of the ACA. Marketplace policies and enrollment were compared in expansion states versus non-expansion states. Public coverage did increase more in states that empowered their Marketplace to enroll publicly-eligible applicants directly into Medicaid/CHIP. This was driven by enrollment policy, not by choice of state-based versus federal-based Marketplaces. Welcome mats were largest in expansion states and increases ranged from 9 to 13 percentage points in enrollment.

Trends in birth rates after elimination of cost sharing for contraception by the Patient Protection and Affordable Care Act.
Researchers evaluated changes in birth rates by income level among commercially insured women before (2008-2013) and after (2014-2018) the elimination of cost sharing for contraception under the Patient Protection and Affordable Care Act (ACA). The analytic sample included over 4.5 million women enrolled in 47,721 health plans. In this cross-sectional study, the researchers found that the elimination of cost sharing for contraception under the ACA was associated with improvements in contraceptive method prescription fills and a decrease in births among commercially insured women. Women with low income had more precipitous decreases than women with higher income, suggesting that enhanced access to contraception may address well-documented income-related disparities in unintended birth rates.

Changes in health care-related financial burden for US families with children associated with the Affordable Care Act.
The Affordable Care Act (ACA) sought to improve access and affordability of health insurance. Although most ACA policies targeted childless adults, the extent to which these policies also impacted families with children remains unclear. The purpose of this study was to examine changes in health care-related financial burden for US families with children before and after the ACA was implemented based on income eligibility for ACA policies.

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.

New evidence of state variation in Medicaid payment policies for dual Medicare-Medicaid enrollees.
The authors developed the first longitudinal database of state Medicaid policies for paying the cost sharing in Medicare Part B for services provided to dual Medicare-Medicaid enrollees (duals), and an index summarizing the impact of these policies on payments for physician office services. Information from 2004-2018 was consolidated from online Medicaid policy documents, state laws, and policy data reported to them by state Medicaid programs. The database showed that in 2018 42 states had policies to limit Medicaid payments of Medicare cost sharing when Medicaid’s fee schedule was lower than Medicare’s. This was an increase from 36 such states in 2004. In most states, combined Medicare and Medicare payments for evaluation and management services provided to duals averaged 78% of the Medicare allowed amount for these services.

The effect of Medicaid expansion on prescriptions for breast cancer hormonal therapy medications.
The purpose of this study was to quantify the effects of the Affordable Care Act Medicaid expansion on prescriptions for effective breast cancer hormonal therapies (tamoxifen and aromatase inhibitors) among Medicaid enrollees. Data from the Medicaid State Drug Utilization Database was used. Findings showed that Medicaid expansion may have had a meaningful impact on the ability of lower-income women to access effective hormonal therapies used to treat breast cancer.

Tobacco cessation in Affordable Care Act Medicaid expansion states versus non-expansion states.
This study examined whether states that expanded Medicaid eligibility under the ACA had increased smoking quit rates, tobacco cessation medication orders, and greater health care utilization compared to patients in non-expansion states. The researchers used electronic health record (EHR) data from 219 community health centers (CHCs) in 10 states that expanded Medicaid as of January 2014. They identified patients aged 19-64 with tobacco use status in their records within six months prior to ACA Medicaid expansion and 1 or more visits. They found that patients in expansion states had increased adjusted odds of quitting, having a medication ordered and having follow-up visits compared to patients in non-expansion states.

The impact Of Medicare's mental health cost-sharing parity on use of mental health care services.
This study examined the impact of Medicare’s mental health cost-sharing parity on use of mental health care services, which was phased in from 2010 to 2014. The authors assessed whether the reduction in mental health cost sharing was associated with changes in specialty and primary care outpatient mental health visits and psychotropic medication fills. They compared people with Medicare and private insurance before and after implementation. Medicare beneficiaries’ use of psychotropic medication increased after implementation but there was not a detectable change in visits.

Impact of higher insulin prices on out-of-pocket costs in Medicare Part D.
In this study, the investigators examined how patients’ out-of-pocket costs for insulin would have dropped from 2014 to 2019 due to Part D policy changes and whether higher insulin prices offset these potential savings. The authors concluded that efforts to reduce patients’
out-of-pocket cost by closing the Medicare Part D coverage gap were largely negated by higher insulin prices.
