The Impact of Recent Republican Health Insurance Reform Proposals Stephen T Parente, Ph.D. & Roger Feldman, Ph.D. University of Minnesota Presented at the American Enterprise Institute, Washington, DC September 20, 2007

Overview Previous research findings on consumer driven health plans ARCOLA Simulation Model Overview 2007 State of the Union proposal 2007 Tax Credit (e.g. Coburn) proposal Implications

‘Classic’ CDHP Model – HRA Health Tools and Resources Care management program Internet enabled Health Coverage Preventive care covered 100% Annual deductible Employer selects expenses that count toward deductible Expenses beyond the deductible usually covered at % Health Reimbursement Arrangement (HRA) Employer allocates $$ to HRA Member directs HRA Balance in HRA rolls over at year-end Applies toward deductible Annual Deductible Preventive Care 100% Health Coverage Annual Deductible HRA $$

Health Savings Account (HSA) Authorized by 2003 law, an HSA account is owned by the enrollee and used to pay for current and future medical expenses Both employee and employer can make tax-free contributions to HSA Health plan design is similar to HRA Bush Administration has proposed refundable tax credits for individuals to purchase health plans with HSAs HSAs are offered by UnitedHealth, the Blues, Aetna, Cigna, Humana, and Kaiser Annual Deductible Preventive Care 100% Health Coverage Annual Deductible HSA $$

Questions Addressed by Previous Peer-Reviewed Research Do CDHPs (in the form of HRAs) have national appeal? –Yes. In almost every major market, when introduced, take-up exceeded 5% of employees offered (range 4% to 85%). Do CDHPs always have favorable selection? –No. While there is some evidence of initial favorable selection in one employer, it does not persist. (Parente, Feldman, Christianson, 2004) Do CDHPs have different effects on cost & utilization compared with other plans? –Yes. Results depend on benefit generosity. Long run costs are not less with a generous plan. (PFC, 2004). For less generous plans, preliminary evidence suggest reduction in rate of increase. –Least cost increase is for pharmacy (Parente, Feldman, Chen, 2007).. Are HSAs a viable approach to addressing the problem of the uninsured? –Yes. But it is still more a political economy question of budget priorities. Reductions in uninsured range from 3 million to 25 million with federal costs as high as $100 billion per year. (Feldman, Parente, et al., 2005).

Q. Do CDHPs Generate Adverse Selection for Other Plan Choices? A. Yes (HSA) and No (HRA)

HSA/PPO Risk Ratio Data from 1 large employer representing ~150,000 covered lives with HSA offered in – 0.99 <0.75 HSA/PPO Ratio Risk Score based 2005 Claims data analysis using RxRisk

High-option HRA/PPO Risk Ratio Data from 1 large employer representing ~50,000 covered lives with HSA offered in – 0.99 <0.75 HSA/PPO Ratio Risk Score based 2005 Claims data analysis using RxRisk

Summary of HSA Choice when HRA and PPO Also Are Choices Risk-splitting between HRA and HSA Clearly an issue of benefit design Selection not limited to HSAs. HMOs also get favorable selection. Is the risk segmentation of value? Is it too difficult to fix short of full-replacement? Next big question: Do HSAs have better/neutral outcomes and satisfaction, adjusted for risk?

Policy Proposal Simulations President Bush’s 2007 State of the Union and the Coburn Proposal (S-1019) Impacts simulated by the ARCOLA (Adjusted Risk Choice & Outcomes Legislative Assessment) model

What Does ARCOLA Do? ARCOLA models national health plan take-up from policy proposals in the individual and group markets Unique combination of attributes: –Uses MEPS for simulation weights –Choices based on claims from 4 large employers matched with employee demographics and plan choices –Includes CDHP choice data in model –Risk-adjustment (Hopkins ACGs) used to predict both individual and group market premiums –Model is iterative –Can identify premium elasticity response to policy options for specific plan choices and the uninsured

Previous Work: 2004 State of the Union Estimates

2007 SOTU Simulation Using the ARCOLA model, we predicted the effect of 2007 SOTU on health insurance take- up and costs –Background: Our model predicted the take-up of HSA plans in the individual market quite accurately (Feldman, Parente et al., 2005) –Population: adults aged who are not students, not covered by public insurance, and not eligible for coverage under someone else’s ESI policy –Baseline uninsurance: 33.7 million people (edited out military, students, age <18 or 65 and older)

SOTU 2007 A tax deduction of $7,500/$15,000 – but you have to have health insurance to get the deduction Health insurance premiums will be taxable (equal tax treatment of individual and ESI (employer sponsored, a.k.a. group, premiums) Complicated incentives created by SOTU cannot be modeled using results from existing economic studies.

Assumptions & Caveats Price after tax credit or tax deduction is actionable at point of purchase of insurance (e.g., don’t want to wait up to 16 month on April 15 th for savings to be realized). Insurance coverage contract is always available. Quasi-national individual insurance market. No new market entrants. Medical CPI is 4% above general inflation. We have a subset of the national population affected. We exclude kids, seniors, students, military and other individuals with govt. insurance. We represent ~75% of target population.

If we let the status quo persist (millions)

Results Uninsurance is reduced by 65% - by at least 20 million people. $104 billion subsidy to the individual market Rest for a subsidy to the ESI market with offsetting tax recovery. Source: Steve Parente and Roger Feldman, ‘ARCOLA’ simulation model, and

Why? Tax subsidy is quite large, even for low- income workers Individuals are sensitive to the prices of different types of health insurance: –Individual HSA policies will increase from 3.1 to 12 million and low-option PPOs from 6 to 16 million –The subsidy covers the full cost of these policies for many people The ESI market is not hollowed out, but expensive PPO plans will disappear

Subsidy cost per person in the individual market, by income

Coburn S-1019, 2007 A tax credit of $2,000 for single person Additional $2,000 credit for spouse Additional $500 credit per child up to a total of $5,000 (assuming two parents) Health insurance premiums will be taxable (equal tax treatment of individual and ESI (employer sponsored, a.k.a. group, premiums)

Results Uninsurance is reduced by 39% to over twenty million. $64 billion subsidy to the individual market. Additional subsidy to the ESI market with offsetting tax recovery of $91 billion Source: Steve Parente and Roger Feldman, ‘ARCOLA’ simulation model, and

Summary of Proposals Could be the most comprehensive US health insurance market proposals ever on both the tax treatment of insurance AND reducing the uninsured by at least 60% Tax deduction is more effective at reducing the uninsured. Overall cost is higher. The Coburn proposal is the most efficient, but with far less impact on the uninsured.

Political Prognosis Without an employer mandate, one can significantly reduce the size of the uninsured be ‘leveling the playing field’ of taxes and health insurance. As long as health care inflation remains significantly above the general inflation rate, almost any proposed expansion will be costly. Channeling consumers to lower cost plans does occur, but the long term cost savings may be beyond ten years and also swamped due to aging population.
