Heart disease poses a significant health and economic burden in the U. S., with considerable variations in outcomes across different racial and ethnic groups. The COVID-19 pandemic has further highlighted the disparities in healthcare utilization and costs associated with heart disease. The authors used the 2021 Merative MarketScan Medicaid claims database to estimate the medical costs and healthcare utilization associated with heart disease by racial and ethnic groups and COVID-19 diagnosis status. This study focused on individuals aged ≥18 years continuously enrolled in a noncapitated insurance plan in 2021. The outcome measures included total medical expenditures and healthcare utilization, including the numbers of emergency department visits and inpatient admissions and length of inpatient stay. The authors employed a generalized linear model with a family of gamma and log links for medical costs, and a negative binomial regression was used for healthcare utilization. Three-way interactions of heart disease, COVID-19 diagnosis, and race and ethnicity categories were implemented after adjusting for age, sex, and comorbidities. The authors reported average marginal effects with 95% CIs. Among 1,008,166 Medicaid beneficiaries, 8% had heart disease in 2021. The cost associated with heart disease was $10,819 per beneficiary in 2021 (95% CI=10,292; 11,347; p
