This study reveals that coding errors in breast cancer cases at our hospital primarily stem from coders' insufficient understanding of relevant rules, overreliance on coding libraries, and inadequate medical record review. Additionally, non-standard documentation practices and diagnostic errors by clinicians are significant contributing factors. Independent predictors of coding errors include the number of diagnoses, length of hospital stay, resuscitation status, and the years of experience of both coders and senior physicians.
