SHADAC Expertise
Medicaid and CHIP Policy
SHADAC has worked both independently and under contract to the Robert Wood Johnson Foundation (RWJF) and the Medicaid and CHIP Payment Access Commission (MACPAC) to monitor and analyze changes in the Medicaid and CHIP policy landscape such as Medicaid expansion, eligibility, enrollment, and renewal, quality measurement, as well as states’ waiver application, implementation, and evaluation. SHADAC faculty and staff have exceptional knowledge of Medicaid and CHIP, including knowledge from the perspective of state policymakers and program administrators, as well as operational issues at the federal and state levels.

Tracking the Data on Medicaid’s Continuous Coverage Unwinding (State Health & Value Strategies)
A lack of publicly available data on Medicaid enrollment, renewal, and disenrollment makes it difficult to understand exactly who is losing Medicaid coverage and for what reasons. This issue brief lays out a phased set of priority measures and provides a model enrollment and retention dashboard template that states can use to monitor both the short-term impacts of phasing out public health emergency (PHE) protections and continuous coverage requirements, as well as longer-term enrollment and retention trends. Through its work with SHVS, SHADAC also published a series of issue briefs that tracked through an interactive map the format of state reporting of unwinding data, state-based marketplace transition data (i.e. people who no longer qualify for Medicaid but might be eligible for a qualified health plan offered through the marketplace), and Medicaid unwinding reinstatement data.
Supporting BDT’s Stabilizing Medicaid Enrollment Learning Collaborative
SHADAC collaborated with a new partner, Benefits Data Trust (BDT), on a small project to design and lead a webinar for its Medicaid Churn Learning Collaborative participants on the topic of monitoring and evaluation. The webinar took place as state Medicaid agency participants were implementing activities to redetermine all individuals enrolled in Medicaid and were meeting federal reporting requirements to monitor the end of the continuous coverage provisions.
Tracking Health Insurance Coverage During the Unwinding: Monthly Data from the Household Pulse Survey
The unwinding of the Medicaid continuous coverage requirement ("Medicaid Unwinding") represents the largest nationwide coverage transition since the Affordable Care Act. Since February 2020, enrollment in Medicaid and the Children’s Health Insurance Program (CHIP) has increased by 23 million enrollees. Not only that, but analysis also indicates that as many as 15 million individuals will exit Medicaid to other coverage or become uninsured. Lack of publicly available data on Medicaid enrollment, renewal, and disenrollment makes it difficult to track the phenomenon of the 'Medicaid Unwinding'. As states “unwind” the Medicaid continuous coverage requirement and restart standard redetermination procedures, SHADAC researchers are using data from the U.S. Census Bureau’s Household Pulse Survey (HPS) to track trends in health insurance coverage rates.

Past Work
Assessment and Synthesis of Selected Medicaid Eligibility, Enrollment, and Renewal Processes and Systems in Six States
SHADAC worked as a contractor for the Medicaid and CHIP Payment Access Commission (MACPAC) to conduct an assessment of Medicaid eligibility, enrollment, and renewal processes and systems in six study states—Arizona, Colorado, Florida, Idaho, New York, and North Carolina. Utilizing a multi-case study methodology as well as key informant interviews with state and local agency staff and advocacy organizations, SHADAC collected and synthesized data on Medicaid enrollment processes and systems for individuals whose income eligibility is based on Modified Adjusted Gross Income (MAGI) in order to assess the extent to which states were achieving desired goals such as program efficiency and a simplified beneficiary experience. As a follow up, SHADAC identified the risks that remain for both individuals and state agencies that cause eligible individuals to remain uninsured or lose Medicaid coverage and conducted interviews with key stakeholders nationally and in four states to obtain additional input on potential risk points and strategies to improve eligibility determination and renewal accuracy.
SHADAC Advocates a Data-based Approach to Advancing Medicaid and CHIP Access Monitoring Plan
On February 17, 2022, the Centers for Medicare & Medicaid Services (CMS) released a request for information (RFI) regarding access to coverage and care in Medicaid and the Children’s Health Insurance Program (CHIP). SHADAC researchers focused our response on Objective 4: Question 1, which asked researchers to consider how CMS might develop a stronger Medicaid and CHIP access monitoring approach through data reporting and analysis. These comments are based on SHADAC’s experience providing data and evaluation technical assistance (TA) to states, and mirror recent testimony to the Medicaid and CHIP Payment Access Commission (MACPAC) provided by SHADAC’s Deputy Director.
Addressing Social Determinants of Health through Behavioral Health-focused 1115 Waivers: Implementation Lessons from Three States
Through the Robert Wood Johnson Foundation’s (RWJF) “Research in Transforming Health” program, SHADAC researchers conducted a study to understand how three states—Illinois, Texas, and Washington—were addressing the needs of justice-involved populations through implementation of Section 1115 Medicaid waiver programs. The specific aim of the study was to identify promising practices and lessons learned related to the development, implementation, and management of these innovative behavioral health policies with the purpose of informing policy development in states considering similar 1115 waivers.

Evaluations of Integrated Care Models for Dually Eligible Beneficiaries: Key Findings and Research Gaps from MACPAC
August 08, 2019:Under contract to the Medicaid and CHIP Payment and Access Commission (MACPAC), researchers at SHADAC recently compiled an inventory of evaluations of integrated care models for beneficiaries enrolled in both Medicare and Medicaid, for which both the inventory itself and a related issue brief have now been published.
About the Study![](https://www.shadac.org/sites/default/files/Evaluations-of-Integrated-Care_0.png)
Currently, both the federal government and numerous states are testing a variety of models to integrate care for beneficiaries enrolled in both Medicare and Medicaid, including the Program of All-Inclusive Care for the Elderly, the Financial Alignment Initiative (FAI), Medicare Advantage dual eligible special needs plans and fully integrated dual eligible special needs plans, managed long-term services and supports programs, and demonstrations that pre-dated the FAI.
There is a limited but growing body of evidence examining the effects of these models on Medicare and Medicaid spending, health outcomes, and access to care. Broadly, studies to date have generally found a decrease in hospitalizations and readmissions for enrollees in the different models relative to those not enrolled in integrated models. Findings regarding the use of other services, such as use of the emergency department and long-term services and supports, were mixed—as are reports on beneficiary experience. It is often difficult to generalize from evaluations of specific models about the effects of integrated care more broadly.
This new inventory details a total of 51 studies, including those published between 2004 to November 2018 and formal evaluations on the FAI updated through July 2019, and gathers all available evidence on how programs have affected spending, quality, health outcomes, and access.

Mental Health and Substance Use Disorder Parity under the ACA: National and State Estimates of Parity Gains as of 2017
In addition to expanding access to health insurance coverage for millions of Americans through subsidized individual market coverage and state Medicaid expansions, the federal Affordable Care Act (ACA) applied Mental Health (MH) and Substance Use Disorder (SUD) coverage and parity mandates to beneficiaries in the individual and small-group markets and to Medicaid expansion beneficiaries. The following brief details the mechanisms by which the ACA applied these mandates and presents national and state-level estimates of the number of people with insurance coverage that must newly provide MH/SUD parity under the ACA. These estimates provide important context for policymakers and others engaged in the ongoing debate about repealing, modifying, or replacing the ACA.
Background
Before the ACA, national legislation regarding equitable coverage for MH/SUD treatments applied only to large-group (i.e., employer-sponsored) health plans, as a result of the Mental Health Parity Act of 1996 (MHPA) and the Mental Health Parity and Addiction Equity Act of 2008 (MHPAEA). The ACA extended these MH/SUD parity protections beyond the large-group market to the individual and small-group markets and to Medicaid expansion beneficiaries by making MH/SUD treatments an essential health benefit (EHB). Before this change, coverage and parity for MH/ SUD treatment in these markets were addressed unevenly across states through a patchwork of state laws.
Expanding Equitable Coverage of Mental Health and Substance Use Disorder Treatment under the ACA: Key Provisions
Findings
Mental Health
In total, an estimated 39 million individuals nationwide had health insurance that was subject to the ACA’s expanded MH parity requirements as of 2017. Of these, 12.1 million were enrolled in individual plans, 14.4 million were enrolled in small-group plans, and almost 13 million were newly eligible Medicaid expansion enrollees.
At the state level, California saw the greatest number of individuals affected at approximately 8.6 million. Other states that had high estimates of affected populations included New York with 2.1 million, Florida with 2.08 million*, Texas with 1.9 million*, and Pennsylvania with 1.87 million.
Vermont, which had pre-ACA parity in both the individual and small-group market and had expanded Medicaid in advance of the ACA, was the only state that saw no effect. Other states such as Wyoming*, Alaska, and Delaware, all had affected populations of less than 100,000 (44,000; 67,000; and 80,000, respectively).
Substance Use Disorder
In total, an estimated 36.4 million individuals nationwide had health insurance that was subject to the ACA’s expanded SUD parity requirements as of 2017. Of these, 9.8 million were enrolled in individual plans, 14 million were enrolled in small-group plans, and almost 12 million were newly eligible Medicaid expansion enrollees.
At the state level, California saw the greatest number of individuals affected at approximately 8.26 million, followed by New York (2.09 million), Florida* (1.79 million), Pennsylvania (1.79 million) and Texas* (1.7 million).
Massachusetts, which had pre-ACA parity in both the individual and small-group market and had expanded Medicaid in advance of the ACA, was the only state that saw no effect. Other states such as Delaware, Wyoming*, Maine*, and Alaska all had affected populations of less than 100,000 (12,000; 39,000; 52,000; and 64,000, respectively).
Discussion
Though the ACA mandated access to health insurance coverage with parity for treatment of mental health and substance use disorders for new groups, it is important to note that the expansion of coverage parity legislation does not guarantee access to equitable MH/SUD services unless the legislation is enforced. Responsibility for parity enforcement falls primarily to states, and the nature and extent of enforcement is consequently inconsistent across the country, with many parity violations continuing to occur as state regulators face limitations in their enforcement capacities.
