Project description:ImportanceThe American Rescue Plan increases premium subsidies for health insurance marketplace enrollees, potentially leading to situations in which enrollees could switch to other health care plans with lower premiums and less cost sharing (ie, deductibles and copayments). Current policy defaults enrollees to their current health care plan if they automatically renew their coverage, which may cause them to stay in health care plans that, because of the American Rescue Plan, are now dominated in that they have higher premiums and cost sharing than other options.ObjectiveTo estimate the extent to which a smart default policy could reduce US health insurance marketplace enrollees' cost sharing and premiums.Design setting and participantsUsing 2018 individual enrollment data and 2021 premium data from California's marketplace and the American Rescue Plan premium tax credit subsidy schedule, this economic analysis estimated the characteristics of enrollees' default health care plans if they defaulted into 2021 health care plans under current and smart default policies. The analysis was conducted from March 20 to April 8, 2021.Main outcomes and measuresCharacteristics of enrollees' default health care plans under current and smart default policies, including net premiums, plan levels, and cost sharing.ResultsThe analytic sample consisted of 748 087 Covered California enrollees from 2018 (mean [SD] age, 44.80 [13.72] years; 408 410 [54.6%] women). Under current policy with the enhanced subsidies implemented under the American Rescue Plan, 5.8% of sample enrollees would default into dominated health plans. Of these enrollees, 98.0% would have incomes below 250% of the federal poverty level. A smart default policy would lead to a mean $102.47 decrease in monthly premiums (95% CI, $103.84-$101.10), a mean $1960 reduction in individual annual medical deductibles (95% CI, $1991-$1928), and a $49.56 reduction in specialty prescription copays (95% CI, $49.77-$49.34).Conclusions and relevanceThe findings of this economic analysis suggest that a smart default policy could avoid defaulting lower-income marketplace enrollees to objectively inferior health care insurance plans and may lead to large reductions in lower-income enrollees' deductibles, copayments, and maximum out-of-pocket amounts. Implementation of a smart default policy could enable marketplace administrators to reduce the prevalence of underinsurance among lower-income marketplace enrollees.

Project description:Disenrollment from health plans purchased on Affordable Care Act (ACA) Marketplaces is frequent; little is known whether disenrollment from off-Marketplace plans is as common or about the experiences and consequences of disenrollment. Using longitudinal administrative data on 2017-2018 nongroup plan enrollment linked with survey data, we analyze plan disenrollment in one regional insurance carrier servicing three states. Overall, 71% of enrollees disenrolled from their 2017 plan. Disenrollment was associated with purchasing through an ACA Marketplace, the carrier making significant changes to an enrollee's plan benefit design, being healthier, being younger, and paying a higher premium for their 2017 plan in 2018. Experiencing financial burden or poor access to preferred providers was not associated with disenrollment. Most disenrollees (93.2%) enrolled in other coverage, often at a lower premium, but lacked confidence that they could afford needed care. These results can inform policy to support enrollees through coverage transitions and foster stability in the nongroup market.

Project description:In concentrated labor markets, where workers have fewer employers to choose from, employers may exploit their monopsony power by contributing less to workers' health benefits. This study examined if labor market concentration was associated with higher worker contributions to health plan premiums. We 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. After controlling for year fixed-effects and market characteristics, we 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 the hypothesis that greater labor market concentration is associated with less generous health benefits. When evaluating the effects of mergers and acquisitions on labor markets, regulatory agencies should critically assess worker contributions to health insurance premiums.

Project description:The health insurance Marketplaces established by the Affordable Care Act include features designed to simplify the process of choosing a health plan in the individual, or nongroup, insurance market. While most individual health insurance enrollees purchase plans through the federal and state-based Marketplaces, millions also purchase plans directly from an insurance carrier (off Marketplace). This study was a descriptive comparison of the decision-making processes and shopping experiences of consumers in two states who purchased a health insurance plan from the same large insurer in 2017, either through the federal Marketplaces or off Marketplace. In a survey, those who selected plans through the Marketplaces reported less difficulty finding the best or most affordable plan than did those enrolling off Marketplace. Respondents in families with chronic health conditions who enrolled through the Marketplaces reported better overall experiences than those who enrolled off Marketplace. Respondents with low health insurance literacy reported poor experiences in enrolling both through the Marketplaces and off Marketplace. Access to consumer assistance in the individual health insurance market should target off-Marketplace populations as well as all populations with low health insurance literacy.

Project description:ObjectiveTo estimate the impact of State Children's Health Insurance Program (SCHIP) expansions on public and private coverage of dependents at small firms compared with large firms.Data sources1996-2007 Annual Demographic Survey of the Current Population Survey (CPS).Study designThis study estimates a two-stage least squares (2SLS) model for four insurance outcomes that instruments for SCHIP and Medicaid eligibility. Separate models are estimated for small group markets (firms with fewer than 25 employees), small businesses (firms under 500 employees), and large firms (firms 500 employees and above).Data collection/extraction methodsWe extracted data from the 1996-2007 CPS for children in households with at least one worker.Principal findingsThe SCHIP expansions decreased the percentage of uninsured dependents in the small group market by 7.6 percentage points with negligible crowd-out in the small group and no significant effect on private coverage across the 11-year-period.ConclusionsThe SCHIP expansions have increased coverage for households in the small group market with no significant crowd-out of private coverage. In contrast, the estimates for large firms are consistent with the substantial crowd-out observed in the literature.

Project description:OBJECTIVE:To examine whether market competition is associated with improved health outcomes in hemodialysis. DATA SOURCES:Secondary analysis of data from a national dialysis registry between 2001 and 2011. STUDY DESIGN:We conducted one- and two-part linear regression models, using each hospital service area (HSA) as its own control, to examine the independent associations among market concentration and health outcomes. DATA COLLECTION:We selected cohorts of patients receiving in-center hemodialysis in the United States at the start of each calendar year. We used information about dialysis facility ownership and the location where patients received dialysis to measure an index of market concentration-the Hirschman-Herfindahl Index (HHI)-for HSA and year, which ranges from near zero (perfect competition) to one (monopoly). PRINCIPAL FINDINGS:An average reduction in HHI by 0.2 (one standard deviation in 2011) was associated with 2.9 fewer hospitalizations per 100 patient-years (95 percent CI, 0.4 to 5.4). If these findings were generalized to the entire in-center hemodialysis population, this would translate to 8,100 (95 percent CI 1,200 to 15,000) fewer hospitalizations in 2011. There was no association between change in market competition and mortality. CONCLUSIONS:Market competition in dialysis may lead to improved health outcomes.

Project description:ObjectiveTo examine the effects of insurance and hospital market concentration on hospital patients' experience of care, as hospitals may compete on quality for favorable insurance contracts.Data sources/study settingSecondary data for 2008-2015 on patient experience from Hospital Compare's patient survey data, hospital characteristics from the American Hospital Association (AHA) Annual Survey, and insurance market characteristics from HealthLeaders-InterStudy.Study designHospital/year-level regressions predict each hospital's patient experience measure as a function of insurance and hospital market concentration and hospital fixed effects. The model is identified by longitudinal variation in insurance and hospital concentration.Data collection/extraction methodsHospital/year-level data from Hospital Compare and the AHA merged by market/year to insurance and hospital concentration measures.Principal findingsChanges in patient satisfaction are positively associated with increases in insurance concentration and negatively associated with increases in hospital concentration. Moving from a market with 20th percentile insurance concentration and 80th percentile hospital concentration to a market with 80th percentile insurance concentration and 20th percentile hospital concentration increases the share of patients that rated the hospital highly from 66.9 percent (95% CI: 66.5-67.2 percent) to 67.9 percent (95% CI: 67.5-68.3 percent) and the share of patients that definitely recommend the hospital from 69.7 percent (95% CI: 69.4-70.0 percent) to 70.8 percent (95% CI: 70.5-71.2 percent). The relationship for insurance concentration is stronger in more concentrated hospital markets, while the relationship for hospital concentration is stronger in less concentrated hospital markets.ConclusionsThese findings add to the evidence on the harms of hospital consolidation but suggest that insurer consolidation may improve patient experience.

Project description:One of the Affordable Care Act's (ACA) signature reforms was creating centralized Health Insurance Marketplaces to offer comprehensive coverage in the form of comprehensive insurance complying with the ACA's coverage standards. Yet, even after the ACA's implementation, millions of people were covered through noncompliant plans, primarily in the form of continued enrollment in "grandmothered" and "grandfathered" plans that predated ACA's full implementation and were allowed under federal and state regulations. Newly proposed and enacted federal legislation may grow the noncompliant segment in future years, and the employment losses of 2020 may grow reliance on individual market coverage further. These factors make it important to understand how the noncompliant segment affects the compliant segment, including the Marketplaces. We show, first, that the noncompliant segment of the individual insurance market substantially outperformed the compliant segment, charging lower premiums but with vastly lower costs, suggesting that insurers have a strong incentive to enter the noncompliant segment. We show, next, that state's decisions to allow grandmothered plans is associated with stronger financial performance of the noncompliant market, but weaker performance of the compliant segment, as noncompliant plans attract lower-cost enrollees. This finding indicates important linkages between the noncompliant and compliant segments and highlights the role state policy can play in the individual insurance market. Taken together, our results point to substantial cream-skimming, with noncompliant plans enrolling the healthiest enrollees, resulting in higher average claims cost in the compliant segment.

Project description:OBJECTIVE:The Affordable Care Act (ACA) introduced reforms to mitigate adverse selection into and within the individual insurance market. We examined the traits and predicted medical spending of enrollees in California post-ACA. DATA SOURCES:Survey of 2,103 enrollees in individual market plans, on- and off-exchange, in 2014. STUDY DESIGN:We compared actual versus potential participants using data from the 2014 California Health Interview Survey on respondents who were individually insured or uninsured. We predicted annual medical spending for each group using age, sex, self-rated health, body mass index, smoking status, and income. PRINCIPAL FINDINGS:Average predicted spending was similar for actual ($3,377, 95 percent CI [$3,280-$3,474]) and potential participants ($3,257 [$3,060-$3,454]); however, some vulnerable subgroups were underrepresented. On- versus off-exchange enrollees differed in sociodemographic and health traits with modest differences in spending ($3,448 [$3,330-$3,565] vs. $3,175 [$3,012-$3,338]). CONCLUSIONS:We did not find evidence of selection into the overall insurance pool in 2014; however, differences by exchange status reflect the importance of including off-exchange enrollees in analyses and the pool for risk adjustment. California's post-ACA individual market has been a relative success, highlighting the importance of state policies and outreach efforts to encourage participation in the market.

Project description:ObjectiveTo examine the effects of hospital and insurer markets concentration on transaction prices for inpatient hospital services.Data sourcesMeasures of hospital and insurer markets concentration derived from American Hospital Association and HealthLeaders-InterStudy data are linked to 2005-2008 inpatient administrative data from Truven Health MarketScan Databases.Study designUses a reduced-form price equation, controlling for cost and demand shifters and accounting for possible endogeneity of market concentration using instrumental variables (IV) technique.Principal findingsThe findings suggest that greater hospital concentration raises prices, whereas greater insurer concentration depresses prices. A hypothetical merger between two of five equally sized hospitals is estimated to increase hospital prices by about 9 percent (p < .001). A similar merger of insurers would depress prices by about 15.3 percent (p < .001). Over the 2003-2008 periods, the estimates imply that hospital consolidation likely raised prices by about 2.6 percent, while insurer consolidation depressed prices by about 10.8 percent. Additional analysis using longer panel data and applying hospital fixed effects confirms the impact of hospital concentration on prices.ConclusionThe findings provide support for strong antitrust enforcement to curb rising hospital service prices and health care costs.
