Uninsured New Yorkers After Full Implementation of the Affordable Care Act: Source of Health Insurance Coverage by Individual Characteristics and Sub-State Geographic Area (Research Report)
Fredric Blavin, Linda J. Blumberg, Matthew Buettgens
The Urban Institute developed a New York state-specific version of its Health Insurance Reform Simulation Model (HIPSM) to support to the state in its effort to assess the implications of the implementation of the Affordable Care Act (ACA). Initial findings from this work were made available in March of 2012.The tables presented here provide sub-state analyses, focusing on those without insurance coverage of any kind prior to reform. We show the share of uninsured expected to gain coverage under the ACA, and include the distribution of characteristics for those anticipated to gain insurance of each type whenever sample sizes allow.
After the Supreme Court Decision: The Implications of Expanding Medicaid for Uninsured Low-Income Midlife Adults (Research Report)
Lynda Flowers, Matthew Buettgens
The Affordable Care Act required states to expand their Medicaid programs to cover more low-income people, including mid-life adults. However, a recent U.S. Supreme Court decision, while upholding the rest of the health reform law, effectively turned the mandate into a state option. This brief examines the Court's decision and how uninsured midlife adults in states that take up this option could benefit.
Medicaid in Alaska Under the ACA (Research Report)
Matthew Buettgens, Christopher Hildebrand
The authors simulate the effect of the Affordable Care Act (ACA) in Alaska, both with and without the Medicaid expansion. The ACA would reduce the uninsured rate in Alaska from 21% without the ACA to 10% under the ACA with the expansion, or 15% without the expansion. The Medicaid expansion would increase enrollment 30% by 2020, while state Medicaid spending on the nonelderly would only increase 3.7%. The report includes a sensitivity analysis of Medicaid take-up rates and detailed characteristics of new enrollees by sub-state region.
Access to Employer-Sponsored Insurance and Subsidy Eligibility in Health Benefits Exchanges: Two Data-Based Approaches (Research Report)
Matthew Buettgens, Stan Dorn, Habib Moody
Consumers offered employer-sponsored insurance (ESI) can be ineligible for subsidies in health insurance exchanges (HIX). Until better ESI data become available, HHS proposes using post-enrollment audits, rather than pre-enrollment verification for this eligibility requirement. Using the Health Insurance Policy Simulation Model (HIPSM), we find that more than 70 percent of eligible consumers work for firms that do not sponsor ESI. HIXes could thus avoid the need to audit them by developing databases that show which employers sponsor ESI. Alternatively, HIXes could target non-ESI recipients for audits based on HIPSM results that show their relative likelihood of being offered ESI.
Small Firm Self-Insurance Under the ACA: Minimum Stop Loss Attachment Points and Adverse Selection in the Fully Insured Small Group Market (Research Report)
Matthew Buettgens, Linda J. Blumberg
The Affordable Care Act changes the small group insurance market substantially, but most of these changes do not apply to self-insured group plans. This exemption provides an opening for small employers with healthier workers to avoid broader sharing of health care risk, isolating higher-cost groups in the fully insured market. We simulate employer decisions under the ACA for a range of stop loss insurance plans, which mediate financial risk, and find that if low-risk stop loss policies are allowed, fully insured small group premiums could be higher by up to 25%. Regulation of stop loss could prevent such adverse selection.
The Cost and Coverage Implications of the ACA Medicaid Expansion: National and State-by-State Analysis (Occasional Paper)
John Holahan, Matthew Buettgens, Caitlin Carroll, Stan Dorn
This paper examines the effect, by state, of the state's decision to adopt the Medicaid expansion. It also estimates the impact of the state’s decision on Medicaid enrollment and the number of uninsured. The paper shows that if all states implement the Affordable Care Act (ACA) Medicaid expansion, the federal government will fund the vast majority of the increase in Medicaid states. Due to several provisions of the ACA, states will face increased enrollment even if they do not implement the Medicaid expansion. The additional cost of implementing the expansion is small relative to total state spending without the expansion and relative to large increases in federal funding and current state budget expenditures.
The Basic Health Program in Utah (Research Report)
Matthew Buettgens, Stan Dorn, Jeremy Roth, Caitlin Carroll
Using the American Community Survey augmented with results from the Urban Institute's Health Insurance Policy Simulation Model, we estimated eligibility, enrollment, and costs for a Basic Health Program (BHP) for Utah under the Affordable Care Act. We find that 55,000 Utahns would qualify for BHP; between 31,000 and 41,000 would likely enroll. Federal BHP payments would likely exceed state costs, with the amount depending on BHP plan cost sharing. BHP would reduce the size of the nongroup exchange by about a quarter, leaving about 120,000 covered lives.
National and State-by-State Impact of the 2012 House Republican Budget Plan for Medicaid (Research Report)
John Holahan, Matthew Buettgens, Caitlin Carroll, Vicki Chen
The House Budget Plan that would repeal the Affordable Care Act (ACA) and convert Medicaid to a block grant would trigger significant decreases in federal Medicaid spending and could result in substantial reductions in enrollment and payments to providers compared to current projections. The analysis finds that projected federal spending on Medicaid for the period 2013 to 2022 would fall by $1.7 trillion compared to current estimates, a 38 percent decline. Of that total, $932 billion in spending reductions would come from the repeal of the federal support for the ACA Medicaid expansion and another $810 billion would be due to federal Medicaid spending reductions that accompany the block grant. State-specific estimates are provided.
Implications of the Affordable Care Act for American Business (Policy Briefs)
Linda J. Blumberg, Matthew Buettgens, Judy Feder, John Holahan
Updated results from our Health Insurance Policy Simulation model show that, contrary to critics' claims, the law has a negligible impact on total employer-sponsored coverage and costs, leaves large business costs-per-person-insured largely untouched and makes small businesses-for whom coverage expands the most-financially better off, through tax credits and market efficiencies that lower premiums. Only among mid-size businesses does the ACA noticeably increase costs, largely due to increased enrollment. Our simulation does not reflect ACA cost containment provisions that may contain private as well as public cost growth-potentially slowing the decline of employer-sponsored health insurance that has been occurring for more than a decade.
Medicaid Expansion Options for Washington (Research Report)
Matthew Buettgens, Randall R. Bovbjerg, Habib Moody
While upholding the Affordable Care Act, the Supreme Court ruled that states could opt out of the Medicaid expansion without losing existing federal funding. In this report, we analyze Medicaid enrollment and costs for Washington under a full expansion to 138% FPL, expansion to 100% FPL, and no Medicaid expansion. By 2020, a full expansion would lead to 256,000 more adults and 16,000 more children enrolled than with no expansion. This would lead to $2.1 billion more in total spending on Medicaid. However, the difference in the state share would only be $115 million. Savings in uncompensated care could offset this increase.
