    • Selection in Massachusetts’s Commonwealth Care Program: Lessons for State Basic Health Plans June 12, 2011Presentation to the 2011 AcademyHealth Annual Research Meeting Deborah Chollet  Allison Barrett  Amy Lischko
    • Acknowledgements  This work was funded by the Robert Wood Johnson Foundation SHARE program  The authors gratefully acknowledge helpful review and comments from the SHARE national program office 2
    • Background: Commonwealth Care Program  CommCare is part of Massachusetts’ 2006 health reform  Individuals must purchase coverage through CommCare to obtain subsidies – Adults age 18-64, below 300% FPL, with no access to public programs or employer-based plans – Full premium subsidies available up to 150% FPL, and partial subsidies to 300% FPL  By end of 2008, enrollment in CommCare was twice as large as the individual commercial market 3
    • Research Questions  Was CommCare successful in enrolling healthy, low-risk individuals? – Adverse selection raises program cost and can make the program unsustainable – Did subsidies help to attract low risk enrollees?  Did CommCare enroll individuals who were similar to individuals buying commercial coverage? – What role did CommCare play in assisting Massachusetts’s commercial insurance reforms? 4
    • Methods and Data Compare demographic characteristics, spending, and service use of enrollees with full, partial, or mixed subsidy status – CommCare eligibility and claims data from October 2006 through December 2008 Compare demographic characteristics of CommCare eligibles – Massachusetts sample of the 2008 ACS Compare spending and service use in individual commercial market – Massachusetts’ 2007-2009 Cost Trends report 5
    • CommCare Enrollees Were Older  By 2008, enrollees were disproportionately older adults, especially partial subsidy group Age Distribution of Eligibles and Enrollees, 2008 CommCare Eligibles CommCare Enrollees Full Partial Full Partial All subsidy subsidy All subsidy subsidy Total 264.0 134.2 129.7 162.3 108.8 33.8 (thousands) Age 18-24 26% 32% 19% 21% 26% 9% Age 25-44 44% 40% 47% 38% 38% 41% Age 45-64 31% 28% 33% 41% 36% 50% Source: Mathematica Policy Research.

    • Average Monthly Costs Declined  Average medical costs declined over time, particularly for partial subsidy group $600Average Monthly Spending $556 Full subsidy $500 Partial subsidy $405 $400 $310 $300 $293 $200 $100 $0 Apr-07 Aug-07 Apr-08 Aug-08 Dec-06 Feb-07 Dec-07 Feb-08 Dec-08 Oct-06 Oct-07 Jun-07 Oct-08 Jun-08 Source: Mathematica Policy Research. 7
    • Full Subsidies and Auto Enrollment Brought In Low Risk Average monthly spending for enrollees 100-150% FPL Low-cost enrollees (under $250) 100% No-cost enrolleesPercent of Enrollees 75% 42% 50% 53% 47% 52% 25% 42% 22% 27% 13% 0% Jan-June July-Sept Oct-Dec Jan-Dec 2007 2007 2007 2008 Partial Full subsidy, Full subsidy, subsidy, no no auto- auto-enroll auto-enroll enroll 8
    • CommCare vs. Commercially Insured Adults  Full subsidy enrollees – much younger than commercially insured – rate of inpatient hospitalization 34% higher – cost 35% less than the commercially insured in 2008 ($475 vs. $307 per month), due to lower prices paid by CommCare carriers  Partial subsidy enrollees – similar in age to commercially insured – rate of inpatient hospitalization 9% lower – cost 35% less than commercially insured ($310 per month) 9
    • Conclusions  Selection improved over time, especially for the partial subsidy population  The fully subsidized population was adversely selected compared to commercially insured individuals  Service use among partial subsidy enrollees was roughly equal to adults in the commercial market 10 Mathematica® is a registered trademark of Mathematica Policy Research.
    • Lessons for Other States Massachusetts created a separate risk pool for uninsured low-income adults, an option for other states under the ACA Basic Health Plans are state-run, and cover individuals between 133-200% FPL outside the Exchange This population in CommCare was similar to commercially insured adults (though it included adults at 200-300% FPL) Enrollees were served more cheaply by Medicaid MCOs 11 Mathematica® is a registered trademark of Mathematica Policy Research.
    • More Lessons States considering a Basic Health Plan should think about: – The effect of diverting a large number of new potential enrollees from the Exchange – The effect on providers of a major expansion of coverage relying on low payment rates – The value of auto-enrollment to balance risk 12 Mathematica® is a registered trademark of Mathematica Policy Research.
