Association of Medicaid expansion with children's insurance coverage and healthcare utilization.

ABSTRACT:

Introduction

In 2014, multiple states expanded Medicaid coverage to low-income adults under the Affordable Care Act. We evaluated the association of Medicaid expansion (ME) with children's insurance coverage and health service utilization.

Methods

We compared changes in children's insurance coverage and health service utilization between 2010-2013 and 2014-2016 in expansion and non-expansion states. Repeated cross-sectional analysis with linear difference-in-differences (DID) models was conducted using the Medical Expenditure Panel Survey.

Results

Medicaid expansion was not associated with changes in the proportion of children with ≥1 month of insurance coverage (DID: -1.9% point [pp], 95% CI -4.1 to 0.3) or the proportion of children with continuous coverage for 12 m
