The Impact of Medicaid Expansion on Continuous Enrollment: a Two-State Analysis.

ABSTRACT:

Background

Discontinuous Medicaid insurance erodes access to care, increases administrative costs, and exposes enrollees to substantial out-of-pocket spending.

Objective

To assess the impact of Medicaid expansion under the Affordable Care Act on continuity of Medicaid coverage among those enrolled prior to expansion.

Design

Using a difference-in-differences framework, we compared Colorado, a state that expanded Medicaid, to Utah, a nonexpansion state, before and after Medicaid expansion implementation.

Participants

Adults ages 18-62 who were enrolled in Medicaid coverage in Colorado and Utah prior to expansion, from the Utah and Colorado All Payer Claims Databases, 2013-2015.

Main measures

The primary outcomes were the duration of Medicaid enrollment and rates of disrupted coverage.

Key results

Following Medicaid expansion, enrollees in Colorado gained an additional 2 months of coverage over two years of follow-up and were 16 percentage points less likely to experience a coverage disruption in a given year relative to enrollees in Utah.

Conclusions

Increasing Medicaid eligibility levels under the Affordable Care Act appears to be an effective strategy to reduce churning in the Medicaid program, with important implications for other states that are considering Medicaid expansion.

Project description:ImportanceMedicaid is an important source of supplemental coverage for older Medicare beneficiaries with low income. Research has shown that Medicaid expansion under the Patient Protection and Affordable Care Act (ACA) was associated with increased Medicaid coverage for previously eligible older adults with low income, but there has been little research on whether their health care use increased or whether such changes differed by beneficiaries' health status.ObjectiveTo assess whether the ACA Medicaid expansion to working-age adults was associated with increased Medicaid enrollment and health care use among older adults with low income with and without chronic condition limitations.Design setting and participantsThis cross-sectional study used data from the National Health Interview Survey from 2010 to 2017 for adults 65 years or older with low income (≤100% of the federal poverty level). Data were analyzed from November 2020 to March 2022.ExposureResidence in a state with Medicaid expansion for working-age adults.Main outcomes and measuresThe main outcomes were Medicaid coverage and health care use, measured by physician office visits and inpatient hospital care. Survey weights were used in calculating descriptive statistics and regression estimates. In multivariate analysis, difference-in-differences models were used to compare changes in outcomes over time between respondents in Medicaid expansion states and respondents in nonexpansion states.ResultsOf 21 859 adults included in the study, 7153 had chronic condition limitations (4983 [70.1%] female; mean [SD] age, 76.0 [0.1] years) and 14 706 did not have chronic condition limitations (9609 [66.3%] female; mean [SD] age, 74.85 [0.08] years). Of those with chronic condition limitations, 2707 (36.7%) were enrolled in Medicaid, 2816 (39.4%) had an office visit in the past 2 weeks, and 2152 (30.7%) used inpatient hospital care in the past year. Medicaid expansion was associated with differential increases in the likelihood of having Medicaid (4.92 percentage points; 95% CI, 0.25-9.60 percentage points; P = .04) and having an office visit in the past 2 weeks (5.31 percentage points; 95% CI, 0.10-10.51 percentage points; P = .046) compared with nonexpansion. There were no differential changes between expansion and nonexpansion states in receipt of inpatient hospital care (-0.62 percentage points; 95% CI, -5.39 to 4.14 percentage points; P = .79). Among adults without chronic condition limitations, 3159 (19.8%) were enrolled in Medicaid, and no differential changes between expansion and nonexpansion states in Medicaid enrollment (-0.24 percentage points; 95% CI, -3.06 to 2.57 percentage points; P = .86) or health care use were found.Conclusions and relevanceIn this cross-sectional study, ACA Medicaid expansion for working-age adults was associated with increased Medicaid enrollment and outpatient health care use among older adults with low income and chronic condition limitations who were dually eligible for Medicare and Medicaid.

Project description:Importance:Medicaid expansion was widely expected to alleviate the financial stresses faced by hospitals by providing additional revenue in the form of Medicaid reimbursements from patients previously receiving uncompensated care. Among nonprofit hospitals, which receive tax-exempt status in part because of their provision of uncompensated care, Medicaid expansion could have released hospital funds toward other community benefit activities. Objective:To examine changes in nonprofit hospital spending on community benefit activities after Medicaid expansion. Design, Setting, and Participants:This cohort study used difference-in-differences analysis of 1666 US nonprofit hospitals that filed Internal Revenue Service Form 990 Schedule H detailing their community benefit expenditures between 2011 and 2017. The analysis was conducted from February to September 2019. Exposures:State Medicaid expansion between 2011 and 2017. Main Outcomes and Measures:Percentage of hospital operating expenditures attributable to charity care and subsidized care, bad debt (ie, unreimbursed spending for care of patients who did not apply for charity care), unreimbursed Medicaid spending, noncare direct community spending, and total community benefit spending. Results:Of 1478 hospitals in the sample in 2011, nearly half (653 [44.2%]) were small hospitals with fewer than 100 beds, and nearly 70% of hospitals (1023 [69.2%]) were in urban areas. Among the 1666 nonprofit hospitals, Medicaid expansion was associated with a decrease in spending on charity care and subsidized care (-0.68 [95% CI, -0.99 to -0.37] percentage points from a baseline mean [SD] of 3.6% [4.0%] of total hospital expenditures; P?<?.001) and in bad debt (-0.17 [95% CI, -0.32 to -0.01] percentage points). There was an increase in unreimbursed spending attributable to caring for Medicaid patients (0.85 [95% CI, 0.60 to 1.10] percentage points; P?=?.04), which canceled out uncompensated care savings from the expansion. Noncare direct community expenditures decreased overall (-0.24 [95% CI, -0.48 to 0.00] percentage points; P?=?.049). Direct community expenditures remained more stable in small hospitals (-0.07 [95% CI, -0.20 to 0.05] percentage points; P?=.26) compared with large hospitals (-0.37 [95% CI, -0.86 to 0.12] percentage points; P?=?.14) and in nonurban hospitals (0.02 [95% CI, -0.09 to 0.14] percentage points; P?=?.70) compared with urban hospitals (-0.36 [95% CI, -0.73 to 0.01] percentage points; P?=?.06). Conclusions and Relevance:In this study, Medicaid expansion was associated with a decrease in nonprofit hospitals' burden of providing uncompensated care, but this financial relief was not redirected toward spending on other community benefits.
