“From the 2005–2013 claims data, we identified pregnant women who had the diagnosis of depression during pregnancy (ICD-9-CM codes of depression: 296.2, 296.20 to 296.25, 296.2, 296.30 to 296.35, 296.82, 300.4, 309.0, 309.1, 309.28, and 311). Only pregnant women with the depression diagnosis for at least 3 times in the outpatient records or for at least once depression diagnosis in the inpatient records were included in the depression cohort. Depressed women with the history of schizophrenia (ICD-9-CM 295), bipolar disorders (ICD-9-CM 296, 296.2, and 296.3) and/or anxiety (ICD-9-CM 300) were excluded.”
