Longitudinal Policy Surveillance of Private Insurance Hearing Aid Mandates in the United States: 1997-2022.

Objectives. To produce a database of private insurance hearing aid mandates in the United States and quantify the share of privately insured individuals covered by a mandate. Methods. We used health-related policy surveillance methods to create a database of private insurance hearing aid mandates through January 2023. We coded salient features of mandates and combined policy data with American Community Survey and Medicare Expenditure Panel Survey-Insurance Component data to estimate the share of privately insured US residents covered by a mandate from 2008 to 2022. Results. A total of 26 states and 1 territory had private insurance hearing aid mandates. We found variability for mandate exceptions, maximum age eligibility, allowable frequency of benefit use, and coverage amounts. Between 2008 and 2022 the proportion of privately insured youths (aged ≤ 18 years) living where there was a private insurance hearing aid mandate increased from 3.4% to 18.7% and the proportion of privately insured adults (19-64 years) increased from 0.3% to 4.6%. Conclusions. Hearing aid mandates cover a small share of US residents. Mandate exceptions in several states limit coverage, particularly for adults. Public Health Implications. A federal mandate would improve hearing aid access. States can also improve access by adopting exception-free mandates with limited utilization management and no age restrictions.

Aging Out of Dependent Coverage and Health Insurance Trends, 2014-2019.

OBJECTIVE: To examine changes in health insurance coverage when adults age out of dependent coverage at age 26 after the implementation of most Affordable Care Act (ACA) provisions. Our analysis also documented differences by sex, race and ethnicity, and state Medicaid expansion status. METHODS: We used a regression discontinuity design and the 2014-2019 American Community Survey to estimate coverage changes (uninsured, any private, employer-sponsored coverage, direct purchase, and Medicaid) at age 26. Our main sample consisted of adult citizens aged 22-29 years. RESULTS: Uninsurance increased by 2.7% points [95% CI; 1.8-3.4] at age 26, which was driven by a significant decline in any private insurance (3.7% point decrease). Young adults experienced a smaller increase in the uninsured rate on turning age 26 in states that expanded in 2014 compared to nonexpansion states (2.2% and 3.2% point increases, respectively), but the difference was not significant (P = .07). Changes in the uninsured rate at age 26 did not differ significantly by sex or race and ethnicity. CONCLUSIONS: The 2010 dependent coverage provision led to more coverage options among young adults and in turn the uninsured rate declined among a population historically among the most likely to lack coverage. The 2014 Medicaid and Marketplace expansions reduced the uninsured rate even further among young adults. Despite important progress, our findings for 2014-2019 were similar to previous studies using pre-ACA data suggesting that coverage loss remains a risk when adults age out of dependent coverage at age 26.

School-Based Health Centers, Access to Care, and Income-Based Disparities.

Importance: School-based health centers (SBHCs) are primary care clinics colocated at schools. SBHCs have the potential to improve health care access and reduce disparities, but there is limited rigorous evidence on their effectiveness at the national level. Objective: To determine whether county-level adoption of SBHCs was associated with access, utilization, and health among children from low-income families and to measure reductions in income-based disparities. Design, Setting, and Participants: This survey study used a difference-in-differences design and data from a nationally representative sample of children in the US merged with SBHC indicators from the National Census of School-Based Health Centers. The main sample included children aged 5 to 17 years with family incomes that were less than 200% of the federal poverty level observed in the National Health Interview Survey, collected between 1997 to 2018. The sample was restricted to children living in a county that adopted a center between 2003 and 2013 or that did not have a center at any time during the study period. Analyses of income-based disparities included children from higher income families (ie, 200% or higher than the federal poverty level). Data were analyzed between January 2020 and July 2023. Exposure: County-by-year SBHC adoption. Main Outcomes and Measures: Outcomes included access (usual source of care, insurance status, barriers), ambulatory care use (general physician, eye doctor, dental, mental health visits), and health (general health status, missed school days due to illness). P values were adjusted for multiple comparisons using the sharpened q value method. Results: This study included 12 624 unweighted children from low-income families and 24 631 unweighted children from higher income families. The weighted percentage of children in low-income families who resided in counties with SBHC adoption included 50.0% aged 5 to 10 years. The weighted percentages of the race and ethnicity of these children included 36.7% Hispanic children, 25.2% non-Hispanic Black children, and 30.6% non-Hispanic White children. The weighted percentages of children in the counties that never adopted SBHCs included 50.1% aged 5 to 10 years. The weighted percentages of the race and ethnicity of these children included 20.7% Hispanic children, 22.4% non-Hispanic Black children, and 52.9% non-Hispanic White children. SBHC adoption was associated with a 6.4 percentage point increase in dental visits (95% CI, 3.2-9.6 percentage points; P < .001), an 8.0 percentage point increase in having a usual source of care (95% CI, 4.5-11.5 percentage points; P < .001), and a 5.2 percentage point increase in insurance (95% CI, 1.2-9.2 percentage points; P = .03). No other statistically significant associations were found with other outcomes. SBHCs were associated with relative reductions in income-based disparities to dental visits by 76% (4.9 percentage points; 95% CI, 2.0-7.7 percentage points), to insured status by 63% (3.5 percentage points; 95% CI, 1.3-5.7 percentage points), and to having a usual source of care by 98% (7.2 percentage points; 95% CI, 5.4-9.1 percentage points). Conclusions and Relevance: In this survey study with difference-in-differences analysis of SBHC adoption, SBHCs were associated with access to care and reduced income-based disparities. These findings support additional SBHC expansion.

State Medicaid and private telemedicine coverage requirements and telemedicine use, 2013-2019.

OBJECTIVE: To examine the association between state Medicaid and private telemedicine coverage requirements and telemedicine use. A secondary objective was to examine whether these policies were associated with health care access. DATA SOURCES AND STUDY SETTING: We used nationally representative survey data from the 2013-2019 Association of American Medical Colleges Consumer Survey of Health Care Access. The sample included Medicaid-enrolled (4492) and privately insured (15,581) adults under age 65. STUDY DESIGN: The study design was a quasi-experimental two-way-fixed-effects difference-in-differences analysis that took advantage of state-level changes in telemedicine coverage requirements during the study period. Separate analyses were conducted for the Medicaid and private requirements. The primary outcome was the past-year use of live video communication. Secondary outcomes included same-day appointment, always able to get needed care, and having enough options for where to go to receive care. DATA COLLECTION/EXTRACTION METHODS: N/A. PRINCIPAL FINDINGS: Medicaid telemedicine coverage requirements were associated with a 6.01 percentage-point increase in the use of live video communication (95% CI, 1.62 to 10.41) and an 11.12 percentage-point increase in always being able to access needed care (95% CI, 3.34 to 18.90). While generally robust to various sensitivity analyses, these findings were somewhat sensitive to included study years. Private coverage requirements were not significantly associated with any of the outcomes considered. CONCLUSIONS: Medicaid telemedicine coverage during 2013-2019 was associated with significant and meaningful increases in telemedicine use and health care access. We did not detect any significant associations for private telemedicine coverage policies. Many states added or expanded telemedicine coverage policies during the COVID-19 pandemic, but states will face decisions about whether to maintain these enhanced policies now that the public health emergency is ending. Understanding the role of state policies in promoting telemedicine use may help inform policymaking efforts going forward.

Association Between Medicaid Dental Payment Policies and Children's Dental Visits, Oral Health, and School Absences.

Importance: Although all state Medicaid programs cover children's dental services, less than half of publicly insured children receive recommended care. Objective: To evaluate the association between the ratio of Medicaid payment rates to dentist charges for an index of services (fee ratio) and children's preventive dental visits, oral health, and school absences. Design, Setting, and Participants: In this cross-sectional study, a difference-in-differences analysis was conducted between September 2021 and April 2022 of 15 738 Medicaid-enrolled children and a control group of 16 867 privately insured children aged 6 to 17 years who participated in the 2016-2019 National Survey of Children's Health. Exploratory subgroup analyses by sex and race and ethnicity were also performed. A 2-sided P < .05 was considered significant. Main Outcomes and Measures: Past-year preventive dental visits (at least 1 and at least 2), parent-reported excellent oral health, and number of days absent from school (at least 4 days and at least 7 days). Results: The Medicaid-enrolled sample included a weighted estimate of 51.20% boys and 48.80% girls (mean age, 11.24 years; Black, 21.65%; Hispanic, 37.75%; White, 31.45%). By weighted baseline estimates, 87% and 48% of Medicaid-enrolled children had at least 1 and at least 2 past-year dental visits, respectively, and 29% had parent-reported excellent oral health. Increasing the fee ratio by 1 percentage point was associated with percentage point increases of 0.18 in at least 1 dental visit (95% CI, 0.07-0.30), 0.27 in at least 2 visits (95% CI, 0.04-0.51), and 0.19 in excellent oral health (95% CI, 0.01-0.36). Increases in at least 2 visits were larger for Hispanic children than for White children. By weighted baseline estimates, 28% and 15% of Medicaid-enrolled children had at least 4 and at least 7 past-year school absences, respectively. Regression estimates for school absences were not statistically significant for the full sample but were estimated to be significantly reduced among girls. Conclusions and Relevance: This cross-sectional study found that more generous Medicaid payment policies were associated with significant but modest increases in children's preventive dental visits and excellent oral health. Further research is needed to understand the potential association between policies that improve access to dental care and children's academic success.

Eligibility for and Enrollment in Medicaid Among Nonelderly Adults After Implementation of the Affordable Care Act.

The Affordable Care Act's (ACA) Medicaid expansion resulted in substantial gains in coverage. However, little research has documented eligibility or participation rates among eligible adults in the post-ACA period in part because of the complexities involved in assigning eligibility status. We used simulation modeling to examine Medicaid eligibility and participation during 2014 to 2017. More than one in five adults were Medicaid eligible in expansion states in the post-ACA period. In contrast, about one in 30 adults were Medicaid eligible in nonexpansion states. While eligibility rates differed substantially by expansion status, participation rates among Medicaid-eligible adults were similar in both sets of states (44% to 46%). These estimates indicate that differences in eligibility rather than in participation rates explained differences in enrollment between expansion and nonexpansion states during the study period. Participation in Medicaid is expected to grow during the coronavirus pandemic. Our study provides baseline estimates for future analyses of enrollment trends.

The Association Between Medicaid Adult Dental Coverage And Children's Oral Health.

Although all state Medicaid programs cover children's dental care, Medicaid-eligible children are more likely to experience tooth decay than children in higher-income families. Using data from the 1999-2016 National Health and Nutrition Examination Survey and the 2003, 2007, and 2011-12 waves of the National Survey of Children's Health, we examined the association between Medicaid adult dental coverage (an optional benefit) and children's oral health. Adult dental coverage was associated with a statistically significant 5-percentage-point reduction in the prevalence of untreated caries among children after Medicaid-enrolled adults had access to coverage for at least one year. These policies were also associated with a reduction in parent-reported fair or poor child oral health with a two-year lag between the onset of the policy and the effect. Effects were concentrated among children younger than age twelve. We estimated declines in poor oral health among all racial and ethnic subgroups, although there was some evidence that non-Hispanic Black children experienced larger and more persistent effects than non-Hispanic White children. Future assessments of the costs and benefits of offering adult dental coverage may consider potential effects on the children of adult Medicaid enrollees.

California's Health4All Kids Expansion And Health Insurance Coverage Among Low-Income Noncitizen Children.

More than one-third of US children receive coverage through Medicaid and the Children's Health Insurance Program (CHIP), but undocumented immigrant children are not eligible for public coverage in most states. California's May 2016 Health4All Kids coverage expansion allowed children with qualifying household incomes to enroll in Medi-Cal, California's Medicaid and CHIP program, regardless of their immigration status. We examined the effects of California's expansion on noncitizen children's uninsurance rates and sources of coverage, using data from the 2012-18 American Community Survey. California's expansion was associated with significant increases of about 9 and 12 percentage points in any coverage and public coverage, respectively. The estimated increase in any coverage translates to a 34 percent decline in the uninsurance rate relative to the preexpansion rate among noncitizen children (26 percent). Counties with an existing program to reduce children's uninsurance rates experienced an increase in coverage earlier than those without a program in effect before the statewide expansion.

Disparities in self-management outcomes by limited English proficiency among adults with heart disease.

There are significant disparities in cardiovascular health outcomes by limited English proficiency (LEP). Self-management plans (SMPs) are associated with better patient outcomes, however little is known about the association of LEP with having an SMP among adults with heart disease. This study examined this association using 2013-2016 California Health Interview Survey data. Among adults that received an SMP, we also examined whether they had a hard copy SMP (print or electronic vs. none), and whether they reported confidence in their ability to manage their heart disease. Our sample included a total of 9102 adults, including 1232 LEP and 7870 English proficient (EP) adults. LEP was associated with significantly lower odds of SMP receipt (Adjusted Odds Ratio [AOR] 0.46, 95% Confidence Interval [CI] 0.31 to 0.68). LEP and EP adults who received an SMP were similarly likely to have a hard copy SMP and report confidence in heart disease management. The finding that LEP adults were less likely than EP adults to receive an SMP may represent a missed opportunity to improve heart health outcomes for this group.

Association Between Changes in Parental Medicaid Vision Coverage and Child Use of Vision Care.

OBJECTIVE: Many low-income children do not receive regular vision care despite the fact that all state Medicaid programs cover these services. The primary objective of this study was to examine whether children were more likely to have at least one past-year eye doctor visit when their parents gained Medicaid vision benefits. Other indicators of child vision care access (ie, unmet needs for glasses and difficulty seeing) and eye doctor visits among Medicaid-enrolled parents were also assessed. METHODS: Difference-in-differences regression analysis leveraged within-state changes to Medicaid adult vision benefits. Study samples included 17,345 children with a Medicaid-enrolled parent and 12,219 parents with Medicaid coverage interviewed during the 2000 to 2013 National Health Interview Survey. RESULTS: Providing Medicaid adult vision coverage was associated with a 5.4 percentage point increase (P = .009) in having at least one past-year eye doctor visit among parents and a 2.8 percentage point increase (P = .01) in this measure among children. These estimates represent increases of 22% and 14%, respectively, relative to unadjusted parent and child visit rates over the study period. These effects appeared to be concentrated among older children ages 12 to 17. Estimates for the other measures of child access to vision care were not statistically significant. CONCLUSIONS: Providing adult vision benefits was associated with having at least one past-year eye doctor visit among low-income children, and may help to reduce income-based disparities in children's receipt of vision care. This research adds to the limited evidence base on the role of public policy in increasing access to vision services.

Adult Medicaid benefit generosity and receipt of recommended health services among low-income children: The spillover effects of Medicaid adult dental coverage expansions.

Low-income children are less likely to receive recommended health services than their high-income counterparts. This paper examines whether the design of parental Medicaid benefit packages could serve as a mechanism for reducing income-based disparities in unmet health care needs, considering dental benefits as a case study. Leveraging state-level changes to adult dental benefits over time, I find that coverage is associated with increases of 14 and 5 percentage points, respectively, in the likelihood of a recent dental visit among parents and children directly exposed to the policy. Child effects appear to be concentrated among younger children under age 12.

Association between Health Insurance and Health among Adults with Diabetes: Evidence from Medicare.

OBJECTIVES: Gaining Medicare eligibility at age 65 is associated with increased health insurance coverage and reduced medical expenditure risk, but few studies have examined changes in health outcomes among adults with a specific chronic condition. This study assessed the association between Medicare eligibility and health among adults with diabetes. DESIGN: Regression discontinuity design to test for discontinuities in healthcare outcomes at age 65 when most US adults become eligible for Medicare. SETTING: National Health Interview Survey, 2006-2016. PARTICIPANTS: Respondents ages 55 to 74 with diagnosed diabetes (n = 13 455). MEASUREMENTS: Primary outcome measures included self-reported fair or poor general health status, any functional limitation, overweight, obese, and body mass index. Secondary outcomes included health insurance coverage, healthcare spending burden, and functional limitations by cause and type. RESULTS: Medicare eligibility was associated with about an 8.0 percentage point reduction in the uninsured rate (95% confidence interval [CI], -9.9 to -6.0 percentage points; P < .001) and declines in high out-of-pocket healthcare expenditures and worry about medical bills. Eligibility was also associated with reductions of about 5.2 [95% CI, -6.9 to -3.6; P < .001] and 4.7 [95% CI, -7.1 to -2.3; P = .001] percentage points in fair or poor health and any functional limitation, respectively. Declines in functional limitations appeared to be driven by reductions in limitations due to diabetes, arthritis, heart problems, and emotional or behavioral problems. Some evidence indicated that Medicare eligibility was associated with a decline in obesity, but estimates were not consistently statistically significant. CONCLUSION: Expanded health insurance coverage and gains in coverage quality may improve health outcomes among older adults with diabetes. J Am Geriatr Soc 68:388-394, 2020.

The Affordable Care Act Appears to Have Narrowed Racial and Ethnic Disparities in Insurance Coverage and Access to Care Among Young Adults.

Prior to the Affordable Care Act, one in three young adults aged 19 to 25 years were uninsured, with substantial racial/ethnic disparities in coverage. We analyzed the separate and cumulative changes in racial/ethnic disparities in coverage and access to care among young adults after implementation of the Affordable Care Act's 2010 dependent coverage provision and 2014 Medicaid and Marketplace expansions. We find that the dependent coverage provision was associated with similar gains across racial/ethnic groups, but the 2014 expansion was associated with larger gains in coverage among Hispanics and Blacks relative to Whites. After the 2014 expansion, coverage increased by 11.0 and 10.1 percentage points among Hispanics and Blacks, respectively, compared with a 5.6 percentage point increase among Whites. The percentage with a usual source of care and a recent doctor's visit also increased more for Blacks relative to Whites. Increases in coverage were larger in Medicaid expansion compared with nonexpansion states for most racial/ethnic groups.

Medicaid Expansion And Marketplace Eligibility Both Increased Coverage, With Trade-Offs In Access, Affordability.

Affordable Care Act (ACA) provisions implemented in 2014 provide a valuable case study regarding the merits of using public versus subsidized private insurance to help low-income people obtain and finance health care. In particular, nonelderly adults with incomes of 100-138 percent of the federal poverty level gained Medicaid eligibility if they lived in states that implemented the ACA's Medicaid expansion, whereas those in nonexpansion states became eligible for subsidized Marketplace coverage. Using data for 2008-15 from the National Health Interview Survey, we found that as of 2015, adults with family incomes in this range had experienced large declines in uninsurance rates in both expansion and nonexpansion states (the adjusted declines were 22 percentage points and 18 percentage points, respectively). 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. There were, however, important differences: Adults in expansion states experienced larger reductions in out-of-pocket spending but also faced greater difficulty accessing physician care relative to adults in nonexpansion states.

Medicaid Expansion Coverage Effects Grew In 2015 With Continued Improvements In Coverage Quality.

Previous research has demonstrated large gains in insurance coverage associated with the Affordable Care Act's (ACA's) Medicaid expansion in 2014. We used detailed federal survey data through 2015 to analyze more recent changes in coverage for low-income adults after the expansion. We found that the uninsurance rate fell in both expansion and nonexpansion states but that it fell significantly more in expansion states. By 2015 the post-ACA uninsurance rate for low-income adults had fallen by 7.5 percentage points more in expansion than in nonexpansion states, a difference that was similar (about 6.8 percentage points) in adjusted regression models. Private coverage increased in nonexpansion states, but significantly less than Medicaid coverage increased in expansion states. Rates of private coverage did not appear to decline in expansion states. Finally, Medicaid expansion was associated with significantly improved quality of health coverage, as reported by low-income adults.

Most Newly Insured People In 2014 Were Long-Term Uninsured.

In 2014-after the implementation of most of the Affordable Care Act provisions, including Medicaid expansions in some states and subsidies to purchase Marketplace coverage in all states-adults who had been uninsured for more than three years represented a larger share of the newly insured, compared to adults who had been insured for shorter periods of time.

Previous Medicaid Expansion May Have Had Lasting Positive Effects On Oral Health Of Non-Hispanic Black Children.

Healthy tooth development starts early in life, beginning even before birth. We present new evidence suggesting that a historic public health insurance expansion for pregnant women and children in the United States in the 1980s and 1990s may have had long-lasting effects on the oral health of the children gaining eligibility. We estimated the relationship between adult oral health and the extent of state public health insurance eligibility for pregnant women, infants, and children throughout childhood separately for non-Hispanic whites, non-Hispanic blacks, and Hispanics. We found that expanded Medicaid coverage geared toward pregnant women and children during their first year of life was linked to better oral health in adulthood among non-Hispanic blacks. Our results also suggested that there might be a benefit to expanded public health insurance eligibility for children at ages 1-6 among non-Hispanic blacks and Hispanics. Medicaid expansions appear to have had long-lasting effects for certain low-income children and helped narrow racial/ethnic disparities in adult oral health.

Changes In Health Status And Care Use After ACA Expansions Among The Insured And Uninsured.

Following the Affordable Care Act's insurance expansion provisions in 2014, the average health status and use of health care within coverage groups has likely changed. Medicaid enrollees and the uninsured were both healthier in 2014 than those respective groups were in 2013. By contrast, those with individual private insurance coverage appeared less healthy as a group.

The effect of Medicaid adult vision coverage on the likelihood of appropriate correction of distance vision: Evidence from the National Health and Nutrition Examination Survey.

BACKGROUND: Medicaid is the main public health insurance program for individuals with low income in the United States. Some state Medicaid programs cover preventive eye care services and vision correction, while others cover emergency eye care only. Similar to other optional benefits, states may add and drop adult vision benefits over time. RESEARCH OBJECTIVE: This article examines whether providing adult vision benefits is associated with an increase in the percentage of low-income individuals with appropriately corrected distance vision as measured during an eye exam. METHODOLOGY: We estimate the effect of Medicaid vision coverage on the likelihood of having appropriately corrected distance vision using examination data from the 2001-2008 National Health and Nutrition Examination Survey. We compare vision outcomes for Medicaid beneficiaries (n = 712) and other low income adults not enrolled in Medicaid (n = 4786) before and after changes to state vision coverage policies. FINDINGS: Between 29 and 33 states provided Medicaid adult vision benefits during 2001-2008, depending on the year. Our findings imply that Medicaid adult vision coverage is associated with a significant increase in the percentage of Medicaid beneficiaries with appropriately corrected distance vision of up to 10 percentage points. CONCLUSION: Providing vision coverage to adults on Medicaid significantly increases the likelihood of appropriate correction of distance vision. Further research on the impact of vision coverage on related functional outcomes and the effects of Medicaid coverage of other services may be appropriate.

The effect of health insurance coverage on medical care utilization and health outcomes: Evidence from Medicaid adult vision benefits.

Increasing the proportion of adults that have regular, comprehensive eye exams and reducing visual impairment due to uncorrected refractive error and other common eye health problems are federal health objectives. We examine the effect of vision insurance on eye care utilization and vision health outcomes by taking advantage of quasi-experimental variation in Medicaid coverage of adult vision care. Using a difference-in-difference-in-difference approach, we find that Medicaid beneficiaries with vision coverage are 4.4 percentage points (p<0.01) more likely to have seen an eye doctor in the past year, 5.3 percentage points (p<0.01) less likely to report needing but not purchasing eyeglasses or contacts due to cost, 2.0 percentage points (p<0.05) less likely to report difficulty seeing with usual vision correction, and 1.2 percentage points (p<0.01) less likely to have a functional limitation due to vision.
