Medicaid Expansion Waivers: What Will We Learn?

Appendix 1: Federal Waiver Evaluation Design

Federal Section 1115 Waiver Evaluation Plan
Domain Research Questions
Medicaid-supported Enrollment in Qualified Health Plans (QHPs) How do states supporting QHP enrollment for newly eligible beneficiaries compare to Medicaid expansion states in terms of access and health outcomes? Are beneficiaries enrolled in QHPs able to access care at similar or better rates, compared to beneficiaries enrolled in Medicaid?
Does provider participation improve under premium assistance?
What is the unmet need for medical care?
Is there continuity of coverage between Medicaid and Marketplace coverage?
How do states supporting QHP enrollment compare to Medicaid expansion states in terms of total spending, especially given premium variability over time with QHPs? How do premium assistance states compare to Medicaid expansion states in terms of per beneficiary spending on direct medical services and capitation payments?
How do premium assistance states compare in terms of states’ administrative costs?
How do states supporting QHP enrollment compare to Medicaid expansion states in terms of take-up rates? Does the take-up rate among likely eligible individuals suggest that premium assistance (i.e., enrollment in QHPs) is more attractive to beneficiaries than traditional Medicaid?
Are there patterns in the timing of Medicaid beneficiary enrollment that may be related to the Marketplace open enrollment period, even though Medicaid beneficiaries are not subject to open enrollment periods?
Beneficiary Engagement/Premium Incentive Structures and Other Financial Contributions To what extent do requirements for premiums act as a disincentive to enrollment? How does requirement to make premium payments to complete enrollment, as compared to following an initial period of enrollment, affect take-up of coverage?
How do the premium amounts affect take-up of coverage?
What effects do premiums appear to have on continuity of coverage? Do incentive programs that require premiums affect continuity of coverage?
What is the effect of premium enforceability rules, such as required time lapses (or “lock-out” periods) before reenrollment?
Beneficiary Engagement/Premium Incentive Structures What strategies are states using to educate beneficiaries about preferred healthy behaviors? What strategies are states using to explain incentives and disincentives? Which are perceived to be effective?
Conditional on qualitative information suggesting successful education strategies, or on survey or focus group data from state evaluations that explores beneficiary understanding, what is the effect of mode, content, and/or timing of education?
To what extent can program incentives encourage Medicaid enrollees to actively participate in their care without impairing access to needed care? To what extent can program incentives encourage Medicaid enrollees to actively participate in their care?
Do program incentives impair access to needed care?
Do incentives for wellness behaviors work? Which behavior incentives yield the greatest relative gains in preventive care?
Which behavior incentives yield the greatest relative gains in management and care of chronic conditions?
Which behavior incentives yield the greatest reductions in dis-incentivized care (i.e., non-emergent ED visits)?
What are the administrative costs to states and managed care companies of implementing incentive programs? What administrative costs do states with healthy behavior incentive programs incur to establish and maintain these programs? To what extent are costs borne by the state versus contracted health plans?

Appendix 2: State Waiver Evaluation Design Plans

Arkansas
# Goals Hypotheses*
1 HCIP beneficiaries will have equal or better access to health care compared with what they would have otherwise had in the Medicaid fee-for-service system over time. Premium Assistance beneficiaries will have equal or better access to care, including primary care and specialty physician networks and services.
Premium Assistance beneficiaries will have lower non emergent use of emergency room services.
Premium Assistance beneficiaries will have lower rates of potentially preventable emergency department and hospital admissions.
Premium Assistance beneficiaries who are young adults eligible for EPSDT benefits will have at least as satisfactory and appropriate access to these benefits.
Premium Assistance beneficiaries will have appropriate access to non-emergency transportation.
2 HCIP beneficiaries will have equal or better care and outcomes compared with what they would have otherwise had in the Medicaid fee-for-service system over time. Premium Assistance beneficiaries will have equal or better access to preventive care services.
Premium Assistance beneficiaries will report equal or better experience in the care provided.
Premium Assistance beneficiaries will have lower non-emergent use of emergency room services.
Premium Assistance beneficiaries will have lower rates of potentially preventable emergency department and hospital admissions.
3 HCIP beneficiaries will have better continuity of care compared with what they would have otherwise had in the Medicaid fee-for-service system over time. Premium Assistance beneficiaries will have fewer gaps in insurance coverage.
Premium Assistance beneficiaries will maintain continuous access to the same health plans, and will maintain continuous access to providers.
Maintenance of continuous access to the same providers.
4 Services provided to HCIP beneficiaries will prove to be cost effective. Premium Assistance beneficiaries, including those who become eligible for Exchange Marketplace coverage, will have fewer gaps in plan enrollment, improved continuity of care, and resultant lower administrative costs
Premium Assistance will reduce overall premium costs in the Exchange Marketplace and will increase quality of care.
The cost for covering Premium Assistance beneficiaries will be comparable to what the costs would have been for covering the same expansion group in Arkansas Medicaid fee-for-service in accordance with STC 68 on determining cost effectiveness and other requirements in the evaluation design as approved by CMS.

* Research questions of interest identified in the development and approval process for the HCIP waiver include those examining the goals of improving access, improving care and outcomes, reducing churning, and lowering costs. The final waiver design collapses some of these hypotheses and identifies measures to assess the four main goals.
Indiana
# Goals Hypotheses
1 Reduce the number of uninsured low income Indiana residents and increase access to health care services. HIP will reduce the number of uninsured Indiana residents with income under 138% FPL over the course of the demonstration.
HIP will increase access to quality health care services among the target population.
POWER account contributions for individuals in the HIP Plus plan are affordable and do not create a barrier to health care access.

  • Few individuals will experience the lockout period because the policy will deter nonpayment of POWER account contributions policy for HIP Plus beneficiaries.
Presumptive eligibility and fast-track prepayments will provide the necessary coverage so as not to have gaps in health care coverage.
Waiver of non-emergency transportation to the non-pregnant and non-medically frail population does not pose a barrier to accessing care.
2 Promote value-based decision making and personal health responsibility. HIP policies will encourage member compliance with required contributions and provide incentives to actively manage POWER account funds, including:

  • HIP policies surrounding rollover and preventive care will encourage beneficiaries’ compliance with required contributions and provide incentives to actively manage POWER account funds.
HIP Plus members will exhibit more cost-conscious healthcare consumption behavior than: a) HIP Basic members; and b) traditional Hoosier Healthwise members in the areas of primary, specialty, and pharmacy service utilization without harming beneficiary health.
HIP’s (i) graduated copayments required for non-emergency use of the emergency department (ED), (ii) ED prior authorization process, and (iii) efforts to expand access to other urgent care settings will together effectively deter inappropriate ED utilization without harming beneficiary health.

  • The graduated copayment structure for non-emergency use of the emergency department will decrease inappropriate ED utilization without harming beneficiary health.
  • The prior authorization process for hospital emergency department use and efforts to expand access to other urgent care settings will decrease inappropriate ED utilization without harming beneficiary health.
3 Promote disease prevention and health promotion to achieve better health outcomes. HIP will effectively promote member use of preventive, primary, and chronic disease management care to achieve improved health outcomes.
4 Promote private market coverage and family coverage options to reduce network and provider fragmentation within families. HIP’s defined contribution premium assistance program (HIP Link) will increase the proportion of Indiana residents under 138% FPL covered by employer-sponsored insurance (ESI).
HIP’s ESI premium assistance option for family coverage will increase the number of low income families in which the parents and children have access to the same provider network.
5 Provide HIP members with opportunities to seek job training and stable employment to reduce dependence on public assistance. Referrals to Department of Workforce Development (DWD) employment resources at the time of application will increase member employment rates over the course of the demonstration.
6 Assure state fiscal responsibility and efficient management of the program. HIP will remain budget-neutral for both the federal and state governments.

The Medicaid population in Michigan will increase significantly relative to states that did not expand their Medicaid programs.
The Medicaid population in Michigan will increase to a similar degree relative to states that did expand their Medicaid programs.
3 Impact on Healthy Behaviors and Health Outcomes:

Emergency Department Utilization

Emergency department utilization among the Healthy Michigan beneficiaries will decrease from the Year 1 baseline.
Healthy Michigan Plan beneficiaries who make regular primary care visits (at least once per year) will have lower adjusted rates of emergency department utilization compared to beneficiaries who do not have primary care visits.
Healthy Michigan Plan beneficiaries who agree to address at least one behavior change will have lower adjusted rates of emergency department utilization compared to beneficiaries who do not agree to address behavior change.
Impact on Healthy Behaviors and Health Outcomes:

Healthy Behaviors

Receipt of preventive health services among the Healthy Michigan Plan population will increase from the Year 1 baseline.
Healthy Michigan Plan beneficiaries who make regular primary care visits (at least once per year) will have higher rates of general preventive services compared to beneficiaries who do not have primary care visits.
Healthy Michigan Plan beneficiaries who complete an annual health risk assessment will have higher rates of preventive services compared to beneficiaries who do not complete a health risk assessment.
Healthy Michigan Plan beneficiaries who agree to address at least one behavior change will demonstrate improvement in self-reported health status compared to beneficiaries who do not agree to address behavior change.
Healthy Michigan Plan beneficiaries who receive incentives for healthy behaviors will have higher rates of preventive services compared to beneficiaries who do not receive such incentives.
Impact on Healthy Behaviors and Health Outcomes:

Hospital Admissions

Adjusted hospital admission rates for Healthy Michigan Plan beneficiaries will decrease from the Year 1 baseline.
Healthy Michigan Plan beneficiaries who make regular primary care visits (at least once per year) will have lower adjusted rates of hospital admissions compared to beneficiaries who do not have primary care visits.
Healthy Michigan Plan beneficiaries who agree to address at least one behavior change will have lower adjusted rates of hospital admission compared to beneficiaries who do not agree to address behavior change.
4 Participant Beneficiary Views of the Healthy Michigan Plan Describe Healthy Michigan Plan enrollees’ consumer behaviors and health insurance literacy, including knowledge and understanding about the Healthy Michigan Plan, their health plan, benefit coverage, and cost-sharing aspects of their plan.
Describe Healthy Michigan Plan enrollees’ self-reported changes in health status, health behaviors (including medication use), and facilitators and barriers to healthy behaviors (e.g. knowledge about health and health risks, engaged participation in care), and strategies that facilitate or challenge improvements in health behaviors.
Understand enrollee decisions about when, where and how to seek care, including decisions about emergency department utilization.
Describe primary care practitioners’ experiences with Healthy Michigan Plan beneficiaries, practice approaches and innovation adopted or planned in response to the Healthy Michigan Plan, and future plans regarding care of Healthy Michigan Plan patients.
5 Impact of Contribution Requirements & MI Health Accounts Cost-sharing implemented through the MI Health Account framework will be associated with beneficiaries making more efficient use of health care services, as measured by total costs of care over time relative to their initial year of enrollment, and relative to trends in the Healthy Michigan Plan’s population below 100% of the Federal Poverty Level that face similar service-specific cost-sharing requirements but not additional contributions towards the cost of their care.
Cost-sharing implemented through the MI Health Account framework will be associated with beneficiaries making more effective use of health care services relative to their initial year of enrollment, as indicated by a change in the mix of services from low-value (e.g., non-urgent emergency department visits, low priority office visits) to higher-value categories (e.g., emergency-only emergency department visits, high priority office visits), and relative to trends in the Healthy Michigan Plan’s population below 100% of the Federal Poverty Level that face similar service-specific cost-sharing requirements but not additional contributions towards the cost of their care. Several questions on the Healthy Michigan Voices Survey also address this hypothesis.
Cost-sharing and contributions implemented through the MI Health Account framework will not be associated with beneficiaries dropping their coverage through the Healthy Michigan Plan.
Exemptions from cost-sharing for specified services for chronic illnesses and rewards implemented through the MI Health Account framework for completing a health risk assessment with a primary care provider and agreeing to behavior changes will be associated with beneficiaries increasing their healthy behaviors and their engagement with healthcare decision-making relative to their initial year of enrollment. Several questions on the Healthy Michigan Voices Survey also address this hypothesis.
This increase in healthy behaviors and engagement will be associated with an improvement in enrollees’ health status over time, as measured by changes in elements of their health risk assessments and changes in receipt of recommended preventive care (e.g., flu shots, cancer screening) and adherence to prescribed medications for chronic disease (e.g., asthma controller medications).
