Eligibility Criteria
Children 12 years and younger (at the time of the qualifying encounter for care) who were diagnosed with biliary atresia, underwent surgical intervention for biliary atresia, and/or had an encounter for care related to biliary atresia at a participating institution during the study period. Patients who did not undergo surgery will be included (e.g. patients who died before surgery).

- Age 12 years and younger at the time of the qualifying encounter during the study period (encompassing patients born between January 2nd, 1999 through December 31st, 2021)
- Diagnosis of biliary atresia, based on one of the following ICD-10 codes:
- Q44.2 Atresia of bile ducts
- Q44.3 Congenital stenosis and stricture of bile ducts
- Q44.4 Disorders of the biliary tract with major complication or comorbidity
- Q44.5 Other congenital malformations of the bile ducts
- Q44.6 Disorders of the biliary tract without major complication or comorbidity
You may not qualify if:
- Patients aged 13 years old or older during the study period (i.e. those born before January 2nd, 1999)
- Patients born and/or diagnosed with biliary atresia after the end of the study period (i.e. those born after December 31st, 2021)
- No diagnosis of biliary atresia
- History of biliary atresia without any episodes of care related to biliary atresia during the study period (e.g. a teenager with history of BA who underwent Kasai procedure as an infant and has no current issues related to their BA and is receiving care for an unrelated reason)
