Treatment Patterns and Survival Outcomes in Patients With Breast Cancer on Medicaid, Pre- and Post-Expansion.

The objective of this study was to evaluate the impact of Medicaid expansion on breast cancer treatment and survival among Medicaid-insured women in Ohio, accounting for the timing of enrollment in Medicaid relative to their cancer diagnosis and post-expansion heterogeneous Medicaid eligibility criteria, thus addressing important limitations in previous studies. Using 2011-2017 Ohio Cancer Incidence Surveillance System data linked with Medicaid claims data, we identified women aged 18 to 64 years diagnosed with local-stage or regional-stage breast cancer (n=876 and n=1,957 pre-expansion and post-expansion, respectively). We accounted for women's timing of enrollment in Medicaid relative to their cancer diagnosis, and flagged women post-expansion as Affordable Care Act (ACA) versus non-ACA, based on their income eligibility threshold. Study outcomes included standard treatment based on cancer stage and receipt of lumpectomy, mastectomy, chemotherapy, radiation, hormonal treatment, and/or treatment for HER2-positive tumors; time to treatment initiation (TTI); and overall survival. We conducted multivariable robust Poisson and Cox proportional hazards regression analysis to evaluate the independent associations between Medicaid expansion and our outcomes of interest, adjusting for patient-level and area-level characteristics. Receipt of standard treatment increased from 52.6% pre-expansion to 61.0% post-expansion (63.0% and 59.9% post-expansion in the ACA and non-ACA groups, respectively). Adjusting for potential confounders, including timing of enrollment in Medicaid, being diagnosed in the post-expansion period was associated with a higher probability of receiving standard treatment (adjusted risk ratio, 1.14 [95% CI, 1.06-1.22]) and shorter TTI (adjusted hazard ratio, 1.14 [95% CI, 1.04-1.24]), but not with survival benefits (adjusted hazard ratio, 1.00 [0.80-1.26]). Medicaid expansion in Ohio was associated with improvements in receipt of standard treatment of breast cancer and shorter TTI but not with improved survival outcomes. Future studies should elucidate the mechanisms at play.

Racial disparities in cancer mortality in patients with gastrointestinal malignancies following Medicaid expansion.

6546 Background: Racial minorities experience disparities in receipt of cancer treatment and survival. The optional Medicaid expansion provision of the Affordable Care Act provided federal funding to participating states to improve healthcare access for disadvantaged populations by expanding Medicaid eligibility criteria. This study aimed to investigate the effect of Medicaid expansion on racial disparities in mortality among patients with gastrointestinal malignancies. Methods: A cross-sectional cohort study of patients with pancreatic ductal adenocarcinoma (PDAC), colorectal cancer (CRC), and gastric adenocarcinoma (GC) of any stage was conducted using the National Cancer Database (2009-2019). Difference-in-difference analysis (DID) was performed to compare adjusted 2-year mortality separately among Black and White patients residing in Medicaid expansion states (MES) and non-expansion states (non-MES) before (2009-2013) and after (2014-2019) expansion. Differences in receipt of surgery and chemotherapy were also evaluated. Results: A total of 86,052 patients were included for analysis, including 19,188 patients with PDAC, 60,404 with CRC, and 6,460 with GC. Two-year mortality decreased among Black patients with PDAC residing in MES compared to non-MES following expansion (DID -9.4%, p<0.001) (Table). Mortality also decreased among Black and White patients with CRC in MES compared to non-MES following expansion (DID -4.2%, p < 0.001 and -2.9%, p = 0.047). Among patients with GC, Black patients in MES experienced a marked reduction in mortality compared to non-MES (DID -7.7%, p = 0.07). Both Black and White stage 3-4 PDAC patients had an increase in receipt of chemotherapy in MES following expansion (DID 3.7%, p=0.28 and DID 2.7%, p=0.20). Rates of surgery, but not chemotherapy receipt, increased among Black patients with stage 4 CRC in MES following expansion (DID 5.7%, p=0.03 and 1.0%, p=0.66, respectively). A greater increase in receipt of chemotherapy was observed among Black patients with stage 4 GC in MES than in non-MES (DID 11%, p=0.06). Conclusions: Medicaid expansion was associated with a greater reduction in 2-year mortality rates for Black patients residing in MES than for those in non-MES. Existing racial disparities in mortality remained the same or worsened in non-MES but in almost all cases were mitigated in MES following Medicaid expansion. [Table: see text]

Medicaid and the Children’s Health Insurance Program: an overview for the pediatric radiologist

In terms of number of beneficiaries, Medicaid is the single largest health insurance program in the US. Along with the Children's Health Insurance Program (CHIP), Medicaid covers nearly half of all births and provides health insurance to nearly half of the children in the country. This article provides a broad introduction to Medicaid and CHIP for the pediatric radiologist with a special focus on topics relevant to pediatric imaging and population health. This includes an overview of Medicaid's structure and eligibility criteria and how it differs from Medicare. The paper examines the means-tested programs within the context of pediatric radiology, reviewing pertinent topics such as the rise of Medicaid managed care plans, Medicaid expansion, the effects of Medicaid on child health, and COVID-19. Beyond the basics of benefits coverage, pediatric radiologists should understand how Medicaid and CHIP financing and reimbursement affect the ability of pediatric practices, radiology groups, and hospitals to provide services for children in a sustainable manner. The paper concludes with an analysis of future opportunities for Medicaid and CHIP.

Are Wealthy Older Adults who use Medicaid Opportunistically Accessing the Program?

ABSTRACT Medicaid is the largest payer of long-term services and supports (LTSS) and millions of older Americans rely on this means-tested program, especially during late life. There has been longstanding concern that wealthy older adults may be accessing the program by opportunistically divesting assets in order to qualify for coverage rather than by having high medical or LTSS expenses on which they spend down their resources to eligibility levels. Few current studies analyze this question longitudinally. Thus, questions remain about whether states need to tighten asset eligibility rules to prevent opportunistic asset divestiture. This analysis explores robust longitudinal data to determine the extent to which older, wealthier Americans accessing Medicaid do so by engaging in opportunistic asset transfer. Our findings demonstrate that this may occur among a relatively small proportion of wealthy people, and that tightening Medicaid eligibility criteria would likely have only a very modest impact on program expenditures.

Lagging coverage for mental health services among children and adolescents through home and community-based Medicaid waivers.

Many states cover mental health home and community-based services (HCBS) for youth through 1915(c) Medicaid HCBS waivers that allow states to waive certain Medicaid eligibility criteria and define high-risk populations based on age, medical condition(s), and disability status. We sought to evaluate how States are covering children and adolescents with mental health needs through 1915(c) waivers compared to other youth waiver populations. Data elements were extracted from Medicaid 1915(c) approved waivers applications for all included waivers targeting any pediatric age range through October 31, 2018. Normalization criteria were developed and an aggregate overall coverage score and level of funding per person per waiver were calculated for each waiver. One hundred and forty-two waivers across 45 states were included in this analysis. Even though there was uniformity in the Medicaid applications, there was great heterogeneity in how waiver eligibility, transition plans, services covered, and wait lists were defined across group classifications. Those with mental health needs (termed serious emotional disturbance) represented 5% of waivers with the least annual funding per person per waiver. We recommend greater links between public policy, infrastructure, health care providers, and a family-centered approach to extend coverage and scope of services for children and adolescents with mental health needs.

Association of Medicaid expansion under the Affordable Care Act and overall survival among children with cancer.

6507 Background: State Medicaid expansions under the Affordable Care Act are associated with increased Medicaid coverage among children, including those with cancer. Since the expansions did not directly affect Medicaid eligibility criteria for children, these changes suggest “welcome mat” effects, where previously uninsured children become enrolled in Medicaid after their parents gain coverage. Insurance improvements from the expansions have been associated with improved cancer outcomes for non-elderly adults. However, it is unclear whether the expansions also impacted childhood cancer outcomes. Methods: Data for children ages 0-14 years diagnosed with cancer from 2011-2017 were queried from central cancer registries covering cancer diagnoses from 43 states as part of the Centers for Disease Control’s National Program of Cancer Registries. The primary outcome was 2-year overall survival. We utilized difference-in-differences analyses to compare changes in 2-year survival from 2011-2013 to 2014-2017 between children who resided in states expanding Medicaid by 2014 vs. states not expanding Medicaid within the study period. Analyses were adjusted for covariates including age, race/ethnicity, sex, metropolitan residence, cancer type, and stage at diagnosis. Results: A total of 42,970 children with cancer were included. Overall, there were increases in 2-year survival among children in expansion states (90.5% in 2011-2013 to 91.4% in 2014-2017) but no change among children in non-expansion states (90.0% in 2011-2013 to 90.0% in 2014-2017). In adjusted difference-in-differences analyses, there was no significant change in survival after Medicaid expansion for children in expansion vs. non-expansion states (1.01 percentage points, 95% CI = -0.23 to 2.25, p = 0.11). In difference-in-differences analyses by race/ethnicity, there was a significant expansion-associated improvement in survival in Black children (3.97 percentage points, 95% CI = 0.02 to 7.93, p = 0.049) but not in White children (0.4 percentage points, 95% CI = -1.07 to 2.04, p = 0.54). There were also expansion-associated improvements in survival among children residing in counties with the lowest quartile of county income (5.88 percentage points, 95% CI = 0.38 to 11.38, p = 0.036) but not for those in higher income counties (1.15, 1.23, and 0.12 percentage points for 2nd, 3rd, and 4th quartiles, respectively). Conclusions: Medicaid expansion, through presumed increases in Medicaid coverage via welcome mat effects, was associated with increased 2-year survival for Black children and children residing in low-income counties. However, the concentration of Black children in states that have not expanded Medicaid highlights the need for further advocacy to more fully achieve improved outcomes. Future data are needed to clarify potential long-term impacts of Medicaid expansion on childhood cancer outcomes.

Improving Care and Service Delivery for Autistic Youths Transitioning to Adulthood

Approximately 100 000 autistic youths turn 18 each year, a rough approximation for the number entering adulthood. Population outcomes among autistic young adults are poor across indicators of physical health, mental health, employment, postsecondary education, community participation, independence, financial security, and access to needed community services. There is little evidence that we have moved the needle on these population-level outcomes over the past 15 years, despite growing attention to the needs of this group and an outpouring of investment in the development of patient-level clinical interventions. The focus on developing evidence-based treatments has not yet been matched by a corresponding investment in implementing interventions at a scale that can reach this growing population or in systems-level strategies for improving policy and program performance.1Historically, autism was conceptualized as a pervasive developmental disorder because difficulties typically manifest pervasively across domains of physical and behavioral health, motor and speech development, and social and emotional development. Thus, delivery of physical health care and health care transition in this population are almost always inextricably intertwined with other developmental domains and a need for communication and coordination with the patient, his or her family, and a myriad of other health and community service providers.2Recommendations for improving care coordination are commonplace in this field and targets for research and practice. However, few specific measures of care coordination exist beyond general questions asked of parents in health care surveys. Implementing continuous improvement practices is impossible without clear metrics to measure progress. A promising direction for measuring care coordination in a way that could inform iterative improvement cycles is the adaptation of social network measures.3 This is a priority of the Autism Intervention Research Network on Physical Health (AIR-P) research node at Drexel University.Medicaid plays a key role in the coordination of care and delivery of services. Poor employment prospects among autistic youth result in Medicaid being among the only potential insurers for this group. Hallmark Medicaid programs, including Section 1115 waivers and other programs that vary by state, can deliver a robust service array to eligible autistic youth. However, a thorough, population-level understanding of the pathways needed to navigate Medicaid during the transition of these youths to adulthood has not been established. There may be specific and modifiable aspects of Medicaid eligibility criteria that differentially affect access for aging autistic youth. The identification of Medicaid services used by enrolled autistic young adults will be a substantial advancement for AIR-P and may reveal avenues to boost the efficiency and effectiveness of service delivery.Across insurers, new service models for transition-aged youth with mental health and chronic health conditions, including peer support and service navigation, are being pilot tested. The adaptation of these innovative models to help autistic youth will be a key goal for AIR-P. Furthermore, among the most critical advancements needed to improve care delivered to autistic youth is reworking the connections between research and practice so that they are both more bidirectional (research informs practice and vice versa) and more efficient (innovation to scalable implementation cycles are faster). Robust networks that foster close connections among researchers, practitioners, and policymakers from the outset of innovation are poised to make much-needed headway for developing and implementing this burgeoning evidence base in a timely manner to truly move the needle on population-level outcomes.

Asset Transfers among those Accessing the Medicaid Program: Are Wealthy Older Adults Gaming the System?

Medicaid is the largest payer of long-term services and supports and millions of older Americans rely on the means-tested program for health care coverage. There has been longstanding concern that wealthy older adults are taking advantage of the program by divesting assets in order to qualify for coverage. The existing research on the issue is somewhat dated, does not focus on the question of asset transfer, and often lacks a significant longitudinal view. Thus, questions remain about whether states need to tighten asset eligibility rules to prevent the wealthier older adults from accessing the program. This analysis explores longitudinal data from the Health and Retirement Study (1998 to 2016) to determine the extent to which wealthier Americans age 50 and older engage in asset transfer to access Medicaid. Our findings demonstrate that this may occur among a relatively small proportion of wealthy older adults, and that tightening Medicaid eligibility criteria would likely have a small to modest impact on the financial status of the program.

Association Of Unemployment With Medicaid Enrollment By Social Vulnerability In North Carolina During COVID-19.

The COVID-19 pandemic precipitated an unemployment crisis in the US that surpassed the Great Recession of 2007-09 within the first three months of the pandemic. This article builds on the limited early evidence of the relationship between the pandemic and health insurance coverage, using county-level unemployment and Medicaid enrollment data from North Carolina, a large state that did not expand Medicaid. We used linear and county fixed effects models to assess this relationship, accounting for county-level social vulnerability, physical and virtual access to Medicaid enrollment, and COVID-19 case burden. Using data from January 2018 through August 2020, we estimated that the passthrough rate-the share of unemployed people who gained Medicaid coverage-was approximately 15percent statewide but higher in more socially vulnerable counties. This low passthrough rate during a period of increased unemployment resulting from the COVID-19 pandemic means that Medicaid was unable to completely fulfill its countercyclical role, in which it grows to meet greater need during periods of widespread economic hardship, because of North Carolina's stringent Medicaid eligibility criteria. Working toward greater adoption of Medicaid expansion may help ensure that the US is better prepared for the next crisis by ensuring access to health insurance coverage.

Identifying the Undeserving Poor: The Effect of Racial, Ethnic, and Anti-Immigrant Sentiment on State Medicaid Eligibility

ABSTRACT In the United States, race and racism are woven into the very fabric of the welfare state. Racial antipathy has undermined public support for benefits perceived as favoring African Americans and has resulted in significant cuts in programs for the poor. Recently, some studies have found that public discussion on immigration has linked attitudes toward Hispanics and illegal immigrants with preferences toward programs once overwhelmingly influenced by racial attitudes. Building on this literature, the present study assesses the effect of racial and ethnic attitudes on state policy outcomes. Specifically, we examine Medicaid eligibility criteria for four categories of beneficiaries, ranked by level of perceived deservingness. We find that eligibility limits are most generous for children, followed by pregnant women and parents. Benefits for “other adults” (low-income non-parents aged 18–64) are subject to more stringent eligibility criteria or entirely unavailable. In contrast with the limits for other groups, the primary attitudinal predictors of Medicaid eligibility limits for the “other adults” category are antipathy toward Blacks, Hispanics, and illegal immigrants. These results confirm that perceptions of deservingness are a central component of U.S. social policy and demonstrate that material policy outcomes – not just policy preferences – are substantially shaped by attitudes toward Hispanics and immigrants as well as African Americans.

A Qualitative Analysis of State Medicaid Coverage Benefits for Allogeneic Hematopoietic Cell Transplantation (alloHCT) for Patients with Sickle Cell Disease (SCD)

Sickle cell disease (SCD) is the most common inherited hemoglobin disorder, affecting approximately 100,000 people in the United States. Allogeneic hematopoietic cell transplantation (alloHCT), also known as bone marrow transplant (BMT), is currently the only established curative option for SCD. However, alloHCT is an optional benefit under Medicaid. This study of alloHCT coverage for patients with SCD aims to understand the scope of state Medicaid coverage benefits and BMT financial coordinators’ experience working with their state Medicaid programs. States estimated to have more than 50 newborns diagnosed with SCD in 2016 and at least one active BMT Clinical Trials Network (1503 [STRIDE 2], NCT02766465) transplant center (TC) were eligible to participate in this study. Qualitative, semi-structured interviews 30 to 60 minutes in length were conducted with BMT financial coordinators via telephone between May and October 2019. A total of 10 BMT financial coordinators from 10 TCs representing eight states (Florida, Georgia, Illinois, Michigan, New York, Pennsylvania, Texas, and Virginia) participated in the semi-structured interviews. Coordinators in all of the included states reported that alloHCT in children with SCD with a human leukocyte antigen-matched sibling donor was covered by their state Medicaid programs. However, only two states (Florida and Texas) had legislative policies mandating coverage of routine medical costs for patients in clinical trials. TCs in two states (Illinois and Pennsylvania) reported accepting out-of-state Medicaid insurance, but only one state (Michigan) covered both travel and lodging for the patient and one caregiver. Four themes emerged when coordinators were asked about their perspectives and experiences working with their corresponding state Medicaid programs: (1) state Medicaid eligibility criteria based on disability were perceived as being restrictive, and Medicaid reimbursement rates were reported to be low; (2) Medicaid fee-for-service plans were perceived as being more comprehensive and easier to navigate compared to comprehensive managed care (CMC) plans; (3) there is a need to address caregiver and financial assistance beyond the health care costs; and (4) completing the insurance authorization process leading up to alloHCT is critical, including peer-to-peer reviews. There is limited legislative policy to help ensure access to clinical trials and provide out-of-state benefits and travel and lodging for Medicaid enrollees with SCD. These data provide insight into potential areas that could influence changes in policy to enhance access to curative therapy for SCD.

How did the Affordable Care Act Medicaid Expansion Affect Coverage and Access to Care for Low-Income Parents Who Were Eligible for Medicaid Before the Law Was Passed?

We use the National Health Interview Survey from 2010 to 2017 and a difference-in-differences approach to assess the impact of the Affordable Care Cct (ACA) Medicaid expansion on coverage and access to care for a subset of low-income parents who were already eligible for Medicaid when the ACA was passed. Any gains in coverage would typically be expected to improve access to and affordability of care, but there were concerns that by increasing the total population with coverage and thereby straining provider capacity, that the ACA would reduce access to care for individuals who were already eligible for Medicaid prior to the passage of the law. We found that the expansion reduced uninsurance among previously eligible parents by 12.6 percentage points, or a 40 percent decline from their 2012–2013 uninsurance rate. Moreover, these effects grew stronger over time with a 55 percent decline in uninsurance 2 to 3 years following expansion. Though we identified very few statistically significant impacts of the expansion on affordability of care, descriptive estimates show substantial declines in unmet needs due to cost and problems paying family medical bills. Descriptively, we find no significant increases in provider access problems for previously eligible parents, and very limited evidence that the Medicaid expansion was associated with more constrained provider capacity. Though sample size constraints were likely a factor in our ability to identify impacts on access and affordability measures, our overall findings suggest that the ACA Medicaid expansion positively affected our sample of low-income parents who met pre-ACA Medicaid eligibility criteria.

Risk adjusting for Medicaid participation in Medicare Advantage.

Determining appropriate capitated payments has important access implications for dual-eligible Medicare Advantage (MA) members. In 2017, MA plans began receiving higher capitated payments for beneficiaries with full vs partial Medicaid when payments started being risk adjusted for level of Medicaid benefits instead of any Medicaid participation. This approach could favor MA plans in states with more generous Medicaid programs where more beneficiaries qualify for full Medicaid and thus a higher capitated payment. To understand this issue, we examined adjusted Medicare spending for dual-eligible beneficiaries across states with differing Medicaid eligibility criteria. Retrospective analysis of 2007-2015 traditional Medicare data for dual-eligible beneficiaries 65years and older. We compared predicted per-beneficiary spending levels after adjusting for any Medicaid participation and for level of Medicaid benefits across states with varying Medicaid eligibility requirements. States with the most generous Medicaid requirements had more dual-eligible beneficiaries with full Medicaid compared with the most restrictive states (median, 82% vs 55%). Nationally, Medicare spending levels were 1.3times greater for full vs partial Medicaid participants (range across states, 0.8-1.7). When per-beneficiary spending was adjusted for level of Medicaid benefits, rather than any Medicaid participation, states with more generous Medicaid eligibility had larger gains in predicted spending per dual-eligible beneficiary than states with less generous Medicaid coverage (1.7% vs 1.3% increase). Distinguishing between partial and full Medicaid in MA payments may disproportionately increase MA payments in states that have more full Medicaid beneficiaries due to more generous Medicaid eligibility.

Medicaid Access During Economic Distress: Lessons Learned From the Great Recession.

Medicaid enrollment increases during economic downturns which imply households using the public health insurance program during coverage gaps due to job loss. However, we provide new evidence demonstrating that the Medicaid program's countercyclical protections against economic downturns are largely concentrated in states with more generous Medicaid eligibility criteria for adults. We exploit the timing of the 2007-2009 Great Recession to compare trends in recession-linked Medicaid enrollment between states with more generous Medicaid eligibility guidelines and states with more restrictive guidelines. For similar effects of the recession, Medicaid enrollment grew larger states in with more generous Medicaid programs. Our work suggests for every 100 people becoming unemployed in states with a restrictive Medicaid program, about 96 would be uninsured, and about 11 would enroll in Medicaid. Conversely, about 49 would be uninsured in a state with more generous Medicaid guidelines and 57 would enroll in Medicaid.

Health Status and Access to Care for the North Carolina Medicaid Gap Population.

BACKGROUND North Carolina remains one of several states that has not expanded Medicaid eligibility criteria to cover all low-income adults, leading to the so-called Medicaid gap, a population ineligible for Medicaid and too poor for premium subsidies through the federal Health Insurance Marketplace. Our objective was to characterize the health care access and health status of the Medicaid gap population in North Carolina.METHODS We combined annual data from the Behavioral Risk Factor Surveillance Survey (2013-2016). Respondents who were uninsured and earning below 100% of the federal poverty guidelines (FPG) were classified as falling within the Medicaid gap and were compared to insured populations below FPG, representing the traditional Medicaid population, and to individuals above the FPG, regardless of insurance status. We reported health care access, receipt of preventive care, and current health status in unadjusted and demographically adjusted models.RESULTS Compared to either traditional Medicaid or above FPG groups, those in the Medicaid gap were 3 times as likely to have no regular source of care and twice as likely to report delaying needed care due to cost. Individuals in the Medicaid gap were more likely than individuals above FPG to report multiple chronic conditions (22% versus 16%) or a functional disability (35% versus 15%), but less likely than the traditional Medicaid population to do so.CONCLUSION While less likely than the traditional Medicaid population to have complex health needs, we found that individuals in the North Carolina Medicaid gap report numerous health care access barriers and lower use of preventive care.

Assessment of Rates of Child Maltreatment in States With Medicaid Expansion vs States Without Medicaid Expansion

Physical abuse and neglect affect a significant number of children in the United States. The 2014 Medicaid expansion, in which several states opted to expand their Medicaid programs, is associated with parental financial stability and access to mental health care. To determine whether Medicaid expansion is associated with changes in physical abuse and neglect rates. This ecological study used state-level National Child Abuse and Neglect Data Systems (NCANDS) data from January 1, 2010, through December 31, 2016, to compare the change in physical abuse and neglect rates in states that chose to expand Medicaid vs those that did not. All cases of physical abuse and neglect of children younger than 6 years during the study period that were referred to state-level Child Protective Services and screened in for further intervention after having met a maltreatment risk threshold were included. Cases with only documented sexual or emotional abuse were excluded. A difference-in-difference analysis was conducted from April 12, 2018, through March 26, 2019. State-level Medicaid expansion status. Incidence rate of screened-in referrals for physical abuse or neglect per 100 000 children younger than 6 years per year by state. Data were analyzed for 31 states and the District of Columbia that expanded Medicaid and 19 states that did not during the study period, with baseline neglect counts of 646 463 and 388 265, respectively. After Medicaid expansion, 422 fewer cases of neglect per 100 000 children younger than 6 years (95% CI, -753 to -91) were reported each year after adjusting for confounders for comparison of postexpansion and preexpansion rates in states that expanded Medicaid contrasting with the change during that time in nonexpansion states. From 2013 to 2016, Medicaid coverage for adults with dependent children increased a median 1.9% (interquartile range, 0.4% to 4.3%) in the states that did not expand Medicaid and 4.2% (interquartile range, 0.9% to 6.0%) in the states that did. No associations were found between Medicaid coverage or Medicaid eligibility criteria and physical abuse or neglect rates. Medicaid expansion was associated with a reduction in the reported child neglect rate, but not the physical abuse rate. These findings suggest that expanding Medicaid may help prevent child neglect.

Changes in Reimbursement to Emergency Physicians After Medicaid Expansion Under the Patient Protection and Affordable Care Act

We examine the effect of Medicaid expansion on reimbursement for emergency physicians' professional services. We conducted a retrospective study using data from a national emergency medicine group in a sample of 50 emergency departments (EDs) from July 1, 2012, to June 30, 2015. We categorized facilities in 14 states into full-expansion (23), partial-expansion (17), and nonexpansion (10) categories based on pre-expansion Medicaid eligibility criteria for all adults. We used a difference-in-differences design to assess the effect of Medicaid expansion on provider reimbursement per visit. Secondary outcomes included reimbursement per relative value unit and relative value units per visit, both overall and by payer type, controlling for age, sex, billing codes, and health system relationship. We studied greater than 6.7 million ED visits during July 2012 to December 2015, 3.0 million pre-expansion and 3.7million postexpansion. After adjusting for covariates, reimbursement per visit increased 6.3% (95% confidence interval 1.4%to11.1%) in full-expansion relative to nonexpansion states and did not change significantly in partial-expansion versus nonexpansion states. Reimbursement per visit for commercial insurance increased 17.1% (95% confidence interval 9.9% to 24.2%) in full-expansion versus nonexpansion states. Reimbursement for self-pay visits increased 9.7% (95% confidence interval 3.7% to 15.7%) in full-expansion versus nonexpansion states. Changes in payments were driven by higher reimbursement per relative value unit; relative value units per visit declined slightly in full-expansion compared with nonexpansion states. In this sample, full Medicaid expansion increased payments for emergency physicians' professional services compared with reimbursement in nonexpansion states. Higher reimbursement was driven primarily by lower proportions of uninsured patients and increased reimbursement per visit for both commercially insured and self-pay patients in states with full Medicaid expansion.

Maternal and child patterns of Medicaid retention: a prospective cohort study

BackgroundWe sought to determine whether maternal Medicaid retention influences child Medicaid retention because caregivers play a critical role in assuring children’s health access.MethodsWe conducted a longitudinal prospective cohort study of a convenience sample of 604 Medicaid-eligible mother-child dyads followed from the infant’s birth through 24 months of age with parent surveys. Individual enrollment status was abstracted from administrative Medicaid eligibility files. Generalized estimating equations quantified the effect of maternal Medicaid enrollment status on child Medicaid retention, adjusting for relevant covariates. Because varying lengths of gaps may have different effects on child health outcomes, Medicaid enrollment status was further categorized by length of gap: any gap, > 14-days, and > 60-days.ResultsThis cohort consists primarily of African-American (94%), unmarried mothers (88%), with a mean age of 23.2 years. In multivariable analysis, children whose mothers experienced any gaps in coverage had 12.6 times greater odds of experiencing gaps when compared to children whose mothers were continuously enrolled. Use of varying thresholds to define coverage gaps resulted in similar odds ratios (> 14-day gap = 11.8, > 60-day gap = 16.8). Cash assistance receipt and maternal knowledge of differences between Temporary Assistance to Needy Families and Medicaid eligibility criteria demonstrated strong protective effects against child Medicaid disenrollment.ConclusionsMedicaid disenrollment remains a significant policy problem and maternal Medicaid retention patterns show strong effects on child Medicaid retention. Policymakers need to invest in effective outreach strategies, including family-friendly application processes, to reduce enrollment barriers so that all eligible families can take advantage of these coverage opportunities.

Who Receives Medicaid in Old Age? Rules and Reality.

Medicaid is a government programme that also provides health insurance to the elderly who have few assets and either low income or catastrophic health care expenses. We ask how the Medicaid rules map into the reality of Medicaid recipiency, and we ask what other observable characteristics are important to determine who ends up on Medicaid. The data show that both singles and couples with high retirement income can end up on Medicaid at very advanced ages. We find that, conditioning on a large number of observable characteristics, including those that directly relate to Medicaid eligibility criteria, single women are more likely to end up on Medicaid – so are non‐white people, but, surprisingly, their higher recipiency is concentrated in the higher income percentiles. We also find that people with low incomes who have a high‐school diploma or higher degree are much less likely to end up receiving Medicaid than their less‐educated counterparts. All of these effects are large and depend on retirement income in a very non‐linear way.

Medical Expenditures Associated With Diabetes Among Youth With Medicaid Coverage.

Background:Information on diabetes-related excess medical expenditures for youth is important to understand the magnitude of financial burden and to plan the health care resources needed for managing diabetes. However, diabetes-related excess medical expenditures for youth covered by Medicaid program have not been investigated recently.Objective:To estimate excess diabetes-related medical expenditures among youth aged below 20 years enrolled in Medicaid programs in the United States.Methods:We analyzed data from 2008 to 2012 MarketScan multistate Medicaid database for 6502 youths with diagnosed diabetes and 6502 propensity score matched youths without diabetes, enrolled in fee-for-service payment plans. We stratified analysis by Medicaid eligibility criteria (poverty or disability). We used 2-part regression models to estimate diabetes-related excess medical expenditures, adjusted for age, sex, race/ethnicity, year of claims, depression status, asthma status, and interaction terms.Results:For poverty-based Medicaid enrollees, estimated annual diabetes-related total medical expenditure was $9046 per person [$3681 (no diabetes) vs. $12,727 (diabetes); P < 0001], of which 41.7%, 34.0%, and 24.3% were accounted for by prescription drugs, outpatient, and inpatient care, respectively. For disability-based Medicaid enrollees, the estimated annual diabetes-related total medical expenditure was $9944 per person ($14,149 vs. $24,093; P < 0001), of which 41.5% was accounted for by prescription drugs, 31.3% by inpatient, and 27.3% by outpatient care.Conclusions:The per capita annual diabetes-related medical expenditures in youth covered by publicly financed Medicaid programs are substantial, which is larger among those with disabilities than without disabilities. Identifying cost-effective ways of managing diabetes in this vulnerable segment of the youth population is needed.
