The Age-stratified Cost of Biliary Atresia: A MarketScan®-Based Cost Analysis

Biliary atresia (BA) is the leading cause of childhood liver failure requiring liver transplantation. Early diagnosis and Kasai portoenterostomy (KP) offer the only opportunity to avoid liver failure and transplantation. This study aimed to assess BA healthcare costs in the United States. We hypothesized that patients who underwent KP before 60 days of age would incur lower healthcare costs than patients who underwent KP at 60 days or older.
