Nonalcoholic fatty liver disease (NAFLD) is characterized by substantial diagnostic and evaluation gaps with no systematic screening. Even recognized cases are undercoded because of the perceived benign nature of disease and current absence of approved pharmacologic treatment. NAFLD is often detected incidentally, particularly in the asymptomatic early phase. We doubled NAFLD detection via natural language processing of 1 million imaging reports combined with laboratory data from an unselected population. We describe NAFLD comorbidities and health care utilization as compared with age, sex, and body mass index matched control subjects.
