Project Title Coding Trend Analyses: Stillbirth - Outpatient Care Setting

Friday, August 30, 2019

The purpose of this report was to compare the frequency of diagnoses for stillbirth in the outpatient care setting using International Classification of Diseases, Ninth Revision, Clinical Modification (ICD-9-CM) versus International Classification of Diseases, Tenth Revision, Clinical Modification (ICD-10-CM) codes. ICD-10-CM code definitions were determined by mapping from ICD-9-CM code definitions using the Centers for Medicare and Medicaid Services (CMS) General Equivalence Mappings (GEMs). Forward-backward mapping (FBM) was used to map ICD-9-CM to ICD-10-CM codes. (1)
