Effects of Medicaid expansion on insurance coverage and health services use among adults with disabilities newly eligible for Medicaid.
The purpose of this study was to explore the impact of Affordable Care Act (ACA) Medicaid expansion on insurance coverage and health services use for adults with disabilities newly eligible for Medicaid. The researchers utilized the 2008-2018 Medical Expenditure Panel Survey data and the Agency for Healthcare Research and Quality (AHRQ) PUBSIM model to identify adults between the ages of 26-64 years with disabilities who were newly Medicaid-eligible in expansion states or would have been eligible in non-expansion states if those states had opted in to ACA Medicaid expansion. The study found that among adults with disabilities who were newly eligible for Medicaid, Medicaid expansion was associated with significant increases in full-year Medicaid coverage, receipt of primary care, receipt of flu shots and a significant decrease in out-of-pocket spending. There were greater improvements for adults with disabilities compared to those without disabilities in full-year Medicaid coverage and receipt of flu shots. The researchers concluded that Medicaid expansion was associated with improvements in full-year insurance coverage, receipt of primary and preventive care, and out-of-pocket spending for adults with disabilities who were newly eligible for Medicaid, and there were greater improvements for adults with disabilities than for adults without disabilities.

Effects of the Children's Health Insurance Reauthorization Act on immigrant children's healthcare access.
The purpose of this study was to estimate the effects of the Children's Health Insurance Reauthorization Act (CHIPRA) on insurance coverage, access, utilization, and health outcomes among immigrant children. The researchers utilized the restricted use 2000-2016 National Health Interview Survey (NHIS)with a sample which included immigrant children between the ages of 0 and 18 born outside the United States, with family income below 300% of the Federal Poverty Level (FPL). The study found that CHIPRA was related with a decrease in uninsured rates and an increase in public insurance enrollment for immigrant children. The effects of CHIPRA became small and statistically not significant 3 years after adoption. The researchers found no significant changes in health care access and utilization, and health outcomes, overall and across subgroups due to CHIPRA. The researchers concluded that the eligibility expansion of CHIPRA was related with increases in public insurance coverage for low-income children. However, no effect of CHIPRA on access to care and health was found.

Association of health insurance coverage disruptions with mortality risk among US working-age adults.
This cohort study assessed associations of a prior coverage disruption with mortality risk among large, nationally representative cohorts of working-age adults aged 18 to 64 with public or private health insurance coverage. Most research had previously been conducted among Medicaid enrollees, and little is known about insurance disruption among privately insured adults. The study used data from the 2000 to 2018 National Health Interview Survey (NIHS), specifically from the NHIS Linked Mortality files which contain data from the National Death Index. All data was deidentified and publicly available. The authors found that disruptions were associated with a higher mortality risk in either publicly or privately insured adults.

Financial outcomes after traumatic injury among working-age US adults with commercial insurance.
This cross-sectional study linked insurance claims and consumer credit report data to evaluate the experience of financial distress in commercially insured adults after traumatic injury. Data from Blue Cross Blue Shield of Michigan’s preferred provider organization insurance claims from 2019 through 2021 were included. The authors identified working-age adults aged 21 to 64 whose January 2021 credit reports occurred more than 6 months after hospital admission for traumatic injury. This cohort of 3164 adults was compared demographically to 2223 patients in the comparison cohort. Relative to the comparison cohort, the post injury cohort had a 23% higher likelihood of having medical debt in collections, a 70% higher amount of medical debt in collections, and a 110% higher bankruptcy rate. For many commercially insured patients, the burden of out-of-pocket costs after hospitalization exceeded their ability to pay and could be associated with bankruptcy risk.

The association between postpartum insurance instability and access to postpartum mental health services: evidence from Colorado.
This study assessed the association between postpartum insurance instability and access to postpartum mental health services. The authors used data from the 2018-2019 Colorado Health eMoms survey, which sampled mothers from the 2018 birth certificate files at 3-6 months and 12-14 months postpartum. Respondents were classified at each time point as stably insured or unstable insured based on postpartum insurance status. Of respondents with public coverage at childbirth, 33.2% experienced postpartum insurance changes compared with 9.5% with private coverage. Respondents were more likely to experience unstable postpartum insurance if they were younger, had incomes of less than $50,000, and were of Hispanic ethnicity. Respondents who experienced postpartum insurance instability had lower odds of reporting that they discussed mental health at a postpartum check-up and received postpartum mental health services.

Impact of the Affordable Care Act's Physician Payments Sunshine Act on branded statin prescribing.
The purpose of this study was to assess the impact of the Affordable Care Act's Physician Payments Sunshine Act (PPSA) and its mandate of disclosing pharmaceutical and medical industry payments to physicians for prescribing branded statins. The study found that the PPSA contributed to a 7% decrease in monthly new prescriptions of brand-name statins over the study period. There was no significant change in generic prescribing. The reduction was concentrated among physicians with the highest tercile of drug spending prior to the enactment of the PPSA, with a decrease of 15% in new branded statin prescriptions. The researchers concluded that the PPSA mandate reduced the prescribing of branded statin prescriptions in the time period following its announcement, especially in physicians who were taking part in excessive prescribing of the branded statins.

The US Medicaid program: coverage, financing, reforms, and implications for health equity.
This article is a literature review of the Medicaid program focusing on Medicaid eligibility, enrollment, and spending and examined areas of Medicaid policy, including managed care, payment, and delivery system reforms; Medicaid expansion; racial and ethnic health disparities; and the potential to achieve health equity. The authors included peer-reviewed articles and reports published between January 2003 and February 2022. Medicaid covered approximately 80.6 million people per month in 2022, representing 16.3% of US health spending. Managed care plans run by states enrolled 69.5% of Medicaid beneficiaries in 2019 and adopted 139 delivery system reforms from 2003 to 2019. Over half (56.4%) of Medicaid beneficiaries were from racial and ethnic minority groups in 2019, and disparities in access, quality, and outcomes are common among these groups within Medicaid. The authors felt that additional Medicaid reforms are needed to reduce health disparities by race and ethnicity and to achieve equity in access, quality, and outcomes.

Association of insurance mix and diagnostic coding practices in New York state hospitals.
This study’s goal was to estimate whether, for the same Medicaid enrollee with multiple hospitalizations, a hospital's share of privately insured patients is associated with the number of diagnoses on claims since privately insured hospitals may invest more in intensive coding than hospitals serving publicly insured patients. This cross-sectional study used patient-level fixed effects regression models on inpatient Medicaid claims from Medicaid enrollees with at least 2 admissions in at least 2 different hospitals in the state of New York between 2010 and 2017. This analysis included 1,614,630 hospitalizations for Medicaid-insured patients (mean age, 48.2 years; 51.4% women and 48.6% men). Overall, 74,998 were Asian, 462,259 Black, 375,591 Hispanic, 486,313 White, 128,896 unknown, and 86,573 other. When the same patient was seen in a hospital with a higher share of privately insured patients, more diagnoses were recorded. Patients discharged from hospitals in the bottom quartile of privately insured patient share received 1.37 more diagnoses when they were subsequently discharged from hospitals in the top quartile, relative to patients whose admissions were both in the bottom quartile. This suggests that payment policy may drive differential investments in infrastructure to document diagnosis, causing a feedback loop that exacerbates resource inequity.

Differences in care between special needs plans and other Medicare coverage for dual eligibles.
This study compared access to, use of, and satisfaction with care among dual eligibles enrolled in Dual Eligible Special Needs Plans (D-SNPs) versus those enrolled in Medicare Advantage (MA) plans and traditional Medicare. Findings showed that, compared with those in traditional Medicare, dual eligibles generally reported greater access to care, preventive service use, and satisfaction with care in D-SNPs. There were, however, fewer differences in these outcomes among dual eligibles in D-SNPs versus other MA plans. Overall, these findings suggested that D-SNPs altogether have not provided consistently superior or more equitable care, and they highlight areas where federal and state policy could strengthen incentives for D-SNPs to improve care.

Do disruptions in health insurance continue to affect access to care even after coverage is regained?
Researchers investigated the association between having a usual source of care provider (USCP) and past disruptions in insurance coverage among insured adults using a longitudinal, nationally representative sample. Using MEPS data, they found that, compared to people who were continuously insured, those with previous insurance coverage disruptions, even short ones, were less likely to have a USCP.

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.

Insurance and geographic variations in non-invasive prenatal testing.
The purpose of this study was to estimate the population-level rate of non-invasive prenatal testing (NIPT) uptake in Massachusetts and identify disparities based on patient zip-code and insurance type. The researchers identified pregnant patients aged 35 years or older at their delivery between 7/1/2015 to 12/31/2015 who were eligible for NIPT use, to assess the role of area‐level sociodemographic characteristics and NIPT uptake. The study reported that considerable geographic variation was discovered. Patients living in zip‐codes within and surrounding the Boston metropolitan area were more likely to receive NIPT, as were those living in Eastern MA. The observed NIPT rate (per 1000 pregnant individuals aged 35 and over) was 48.7 for Medicaid enrollees and 272.1 for commercial enrollees; 123.0 and 223.2 for patients living in a zip‐code with a high versus low proportion of Black/Hispanic residents; and 107.7 and 218.4 for those in a zip‐code with a high versus low proportion of low‐income residents. The researchers reported that birthing people covered by Medicaid were over five times less likely to receive NIPT than their counterparts with commercial coverage. Lower NIPT rates in zip‐codes with a high proportion of low‐income or Black/Hispanic residents also suggests that geographic variations in uptake may reflect racial/ethnic and income disparities independent of insurance coverage. The researchers concluded that the study findings emphasize the presence of substantial disparities in NIPT uptake based on insurance and zip-code of residence, and that further research is needed to identify barriers and facilitators to uptake and to evaluate interventions to address inequities in NIPT use.

Medicare Advantage coverage restrictions for the costliest physician-administered drugs.
This study examined the use of step therapy, prior authorization, and Part D formulary exclusion by 4 large Medicare Advantage (MA) insurers to manage 20 physician-administered drugs with the highest total Medicare expenditures (top 20 drugs). The authors used data from United Healthcare, CVS/Aetna, Humana, and Kaiser plans to create a database of 2020 Part B coverage restrictions and conducted a retrospective analysis of 2018-2020 Part D formularies. For each insurer, they calculated the number of top 20 physician-administered drugs subject to prior authorization and step therapy. Among the 4 insurers, 16 physician-administered drugs were covered on all or some of the Part D formularies in 2018, which decreased to 6 in 2020.

Association of high-deductible health plan enrollment with spending on and use of lenalidomide therapy among commercially insured patients with multiple myeloma.
The purpose of this study was to evaluate the relationship between High-deductible health plan (HDHP) enrollment with out-of-pocket spending and uptake of and adherence to lenalidomide anti-cancer therapy. The researchers found that among the highest spenders (95th percentile), HDHP enrollees paid $376 and $217 more for their first and any lenalidomide prescription fill, respectively, compared with non-HDHP enrollees in the 6 months after initiation. High-deductible health plan enrollment was also associated with an increased risk of paying more than $100 for the initial lenalidomide prescription fill. The study concluded that enrollment in HDHP was associated with higher out-of-pocket spending per lenalidomide prescription fill; however, no statistically significant differences in adherence patterns between HDHP and non-HDHP enrollees were observed.

Association of the Patient Protection and Affordable Care Act with ambulatory quality, patient experience, utilization, and cost, 2014-2016.
The national impact of the Patient Protection and Affordable Care Act (ACA) continues to be debated. The purpose of this cross-sectional study was to determine the relationship between the ACA and ambulatory quality, patient experience, utilization, and cost by comparing outcomes before (2011-2013) and after (2014-2016) ACA implementation. The study focused on United States adults between 18 and 64 years of age with income less than and greater than or equal to 400% of the federal poverty level (FPL), who had responded to the annual Medical Expenditure Panel Survey. Researchers conducted analysis of data from a sample of 123,171 individuals between January 2021 and March 2022. The study found that after the implementation of ACA, adults with income levels less than 400% of the FPL received increased high value care such as diagnostic and preventive testing when compared with adults with income 400% or higher of the FPL, and there were no differences in the other quality measures. Individuals with income less than 400% of the FPL had greater improvements in access, experience, and communication measures compared with those who had income greater than or equal to 400% of the FPL. Receipt of primary care services increased for individuals with lower income compared to individuals with higher income and for those with lower income compared to those with higher income, total out-of-pocket expenditures decreased. There were no other differences in utilization or cost between those groups. The researchers concluded that in this study, the ACA was not associated with changes in utilization, quality, or cost, but was related to decreased out-of-pocket expenditures and improved patient access, communication, and experience.

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.

The Affordable Care Act Medicaid expansion, social disadvantage, and the practice location choices of new general internists.
This study’s objective was to examine the level of social disadvantage of the areas of Medicaid expansion states from the ACA that gained new physicians and the areas of nonexpansion states that lost them. The authors used American Community Survey data to classify commuting zones as high, medium, or low social disadvantage. The AMA Physician Masterfile data from 2009-2019 was used to compare where 32,102 new general internists located during the 6 years following the expansion to where they located during the 5 years preceding the expansion. They estimated that between 2014 and 2019 nonexpansion states lost 371 new general internists to expansion states. However, 62.5% of the physicians lost by nonexpansion states were lost from high disadvantage areas although those areas only account for 17.9% of the population of nonexpansion states. This potentially compromises access for all residents irrespective of insurance coverage.

Changes in postpartum insurance coverage in the US during the COVID-19 pandemic.
The purpose of this study was to examine changes in postpartum insurance loss or changes (churn) in Medicaid-insured pregnant people during the COVID-19 pandemic. The researchers utilized the 2019 to 2021 Current Population Survey, Annual Social and Economic Supplement
(CPS-ASEC), with an annual sample size of approximately 98,000 households. The study covered 3 time periods: prepandemic (2019), early pandemic (2020), and pandemic (2021), and included female respondents aged 18 to 44 years who were living with a child
younger than 1 year at the time. Coverage was assigned to one of three categories: private, Medicaid, or uninsured. Churn was defined as loss of insurance or changes in insurance type between current insurance and insurance in the previous year. The study found that in 2019 (before the pandemic), among postpartum respondents with Medicaid during the last year, 88.2% had consistent Medicaid, 10.3% lost coverage, and 1.6%switched to private coverage. In 2021 (during the pandemic), consistent Medicaid increased by 6.8 percentage points and Medicaid-uninsured churn decreased by 6.6 percentage points representing a 64% decline from 2019. The researchers concluded that postpartum insurance loss decreased during the pandemic, primarily associated with large increases in consistent Medicaid coverage, and that these findings suggest that the Families First Coronavirus Response Act, which prevented Medicaid disenrollment, was associated with substantial reductions in postpartum Medicaid loss.

Researchers examined whether widespread eligibility for Medicare at age 65 narrows disparate preventive service use by race and ethnicity. Using MEPS data and examining six preventive services, they found that, for non-Hispanic Black adults, preventive service use increased after age 65. Further, for all four preventive health measures that were lower for Hispanic adults compared with non-Hispanic White adults prior to age 65, service use was indistinguishable between these groups after reaching the Medicare eligibility age. They concluded that Medicare eligibility appeared to reduce most racial and ethnic disparities in preventive service use.

Labor market concentration and worker contributions to health insurance premiums.
This study’s objective was to examine if labor market concentration was associated with higher worker contributions to health plan premiums. The authors combined publicly available data from the Census to calculate labor market concentration and the Medical Expenditure Panel Survey Insurance/Employer Component to determine premium contributions from 2010 to 2016 for metropolitan areas. They found that higher labor market concentration was associated with higher worker contributions to health plan premiums, lower take-home income, and no change in employer contributions to premiums consistent with their hypothesis.

The role of primary care in the initiation of opioid use disorder treatment in statewide public and private insurance.
This observational study’s goal was to determine if individuals newly diagnosed with opioid use disorder (OUD) who saw a primary care provider (PCP) before or on the date of diagnosis had higher rates of medication treatment for OUD (MOUD). Claims data from Medicaid and a large private insurer in North Carolina from January 2014 to July 2017 was used. During the period from 2014 to 2017, the prevalence of diagnosed OUD increased by 47% among Medicaid enrollees and by 76% among the privately insured. Over the same time period the number of people with an OUD who received MOUD fell among both groups, while PCP involvement in treatment increased. The percent of Medicaid enrollees receiving buprenorphine from a PCP increased from 32% in 2014 to 39% in 2017. In the 12 months before being newly diagnosed, approximately 82% with Medicaid or private insurance had a PCP visit. There was no difference in receiving an MOUD with those who had not seen a PCP. However, there was a higher probability of receiving MOUD with a PCP, than seeing an emergency provider, but lower than seeing a behavioral health specialist or other provider type.

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.

Do high-deductible health plans affect price paid for childbirth?
The purpose of this study was to test whether out-of-pocket costs and negotiated hospital prices for childbirth change after enrollment in high-deductible health plans (HDHPs) and whether price effects differ in markets with more hospitals. Administrative medical claims data from three large commercial insurers with plans in all U.S. states was provided by the Health Care Cost Institute. Findings showed that prices for childbirth in markets with more hospitals decreased after HDHP switch due to lower hospital prices for HDHPs relative to prices at those same hospitals for non-HDHPs.

Eligibility for and enrollment in Medicaid among nonelderly adults after implementation of the Affordable Care Act.
The authors used simulation modeling to examine Medicaid eligibility and participation during 2014 to 2017. They found that more than one in five adults were Medicaid-eligible in expansion states, while about one in 30 adults were Medicaid-eligible in non-expansion states. Further, while eligibility rates differed substantially by expansion status, participation rates among Medicaid-eligible adults were similar in both sets of states, indicating that differences in eligibility, rather than in participation rates, explained differences in enrollment between expansion and non-expansion states during the study period.

Medicaid, health, and the moderating role of neighborhood characteristics.
The purpose of this study was to evaluate whether the characteristics of different neighborhoods have an impact on the interaction between local environment and the effect of health insurance on health. The researchers utilized existing data from the Oregon Health Insurance Experiment and combined it with new, expanded data on neighborhood characteristics to assess whether those characteristics impacted the relationship between getting health insurance and health outcomes. The study found that the multiple domains of neighborhood characteristics did not affect the correlation between insurance and health outcomes, and concluded that Medicaid expansions do not differ greatly in effectiveness across neighborhoods.
