This study analyzed electronic health record (EHR) data from 2016 through 2019 from a federally qualified health center (FQHC) serving predominantly low-income Latine immigrants in the Washington, D.C. metropolitan area to examine how changes in health insurance coverage relate to changes in health care use. Federally qualified health center clients were insured for an average of 59% to 63% of their annual visits, but about one-third had no coverage throughout the year. Findings from descriptive regression and within-client fixed effects models indicate that in years with higher proportions of insured visits, clients averaged more medical visits and interpreter services but fewer mental health and care coordination visits. Latine immigrant clients in D.C., a city with a universal health insurance option, had health insurance coverage for 89% of their visits, and averaged more medical and fewer coordination visits relative to those in a neighboring county in a state without a universal insurance option.
