Validity of using ICD-9-CM codes to identify selected categories of obstetric complications, procedures and co-morbidities.
The ability to measure and track changes in risk-adjusted obstetric complication rates using administrative data underpins efforts to improve obstetric quality of care, but the validity of this approach has not been adequately evaluated. We sought to assess the validity of using composites of ICD-9-CM codes to identify selected categories obstetric complications and risk factors associated with complications. ⋯ For selected categories of obstetric complication diagnoses, use of composite sets of ICD-9-CM codes may be a valid method to identify patients within these complication categories.
