How Do Medicaid Agencies Improve Substance Use Treatment Benefits? Lessons from Three States' 1115 Waiver Experiences.

CONTEXT: In 2015, the Centers for Medicare and Medicaid Services (CMS) urged state Medicaid programs to use 1115 waiver demonstrations to expand substance use treatment benefits. We analyzed four critical points in states' decision-making processes before expanding benefits. METHODS: We conducted qualitative cross-case comparison of three states that were early adopters of the 1115 waiver request. We conducted 44 interviews with key informants from CMS, Medicaid, and other state agencies, providers, and managed care organizations. FINDINGS: Policy makers expanded substance use treatment in response to "fragmented" care systems and unsustainable funding streams. Medicaid staff had mixed preferences for implementing new benefits via 1115 waivers or state plan amendments. The 1115 waiver process enabled states to provide coverage for residential benefits, but state plan amendments made other services permanent parts of the benefit. Medicaid agencies relied on interorganizational networks to identify evidence-based practices. Medicaid staff secured legislative support for reform by focusing on program integrity concerns and downstream effects of substance use rather than Medicaid beneficiaries' needs. CONCLUSIONS: Decision-making processes were influenced by Medicaid agency characteristics and interorganizational partnerships, not federal executive branch influence. Lessons from early-adopter states provide a road map for other state Medicaid agencies considering similar reform.

Medicaid family planning waivers in 3 States: did they reduce unwanted births?

Effects of Medicaid family planning waivers on unintended births and contraceptive use postpartum were examined in Illinois, New York, and Oregon using the Pregnancy Risk Assessment Monitoring System. Estimates for women who would be Medicaid eligible "if" pregnant in the waiver states and states without expansions were derived using a difference-in-differences approach. Waivers in New York and Illinois were associated with almost a 5.0 percentage point reduction in unwanted births among adults and with a 7 to 8.0 percentage point reduction, among youth less than 21 years of age. Oregon's waiver was associated with an almost 13 percentage point reduction in unintended, mostly mistimed, births. No statistically significant effects were found on contraceptive use.

Emergency department utilization in the Texas Medicaid emergency waiver following Hurricane Katrina.

OBJECTIVE: To estimate the enrollment and emergency department (ED) utilization in TexKat, the Texas Medicaid emergency waiver implemented following Hurricane Katrina. DATA SOURCES: Individual-level enrollment and utilization data from the 2005 Medicaid Analytic Extract. STUDY DESIGN: Descriptive analysis is performed on variables that describe enrollment levels, the demographic characteristics of enrollees, and the most common diagnoses in ED visits. A Poisson regression model is also employed to quantify the factors related to an enrollee's probability of having an ED visit and the average number of ED visits. PRINCIPAL FINDINGS: There were 44,246 individuals enrolled in TexKat in 2005. Roughly 13% of these enrollees had at least one ED visit during the sample period, with one quarter of these individuals having more than one visit. Across all enrollees the most common diagnosis was "other upper respiratory infection," but there were significant differences in diagnosis patterns across racial/ethnic groups. The regression analysis suggests little difference in ED utilization across genders, but significant contrasts across racial/ethnic and age groups. CONCLUSIONS: As very little is known about Medicaid emergency waivers, our analysis may provide important information to policymakers who have to react quickly following a disaster. Our findings may help providers estimate potential increases in ED utilization and prepare for relatively common diagnoses. Furthermore, the analysis across racial/ethnic groups may help government officials identify important areas for outreach among vulnerable populations.
