Abstract: An electronic medical record data analysis system and an electronic medical record data analysis method are provided. The electronic medical record data analysis system includes a storage device and a processor. The storage device is configured to store an electronic medical record data analysis module and a post-processing module. The processor obtains electronic medical record data. The processor executes the electronic medical record data analysis module to analyze the electronic medical record data and generate a plurality of disease diagnosis codes and a plurality of correlation degree scores corresponding to the electronic medical record data. The processor sorts the plurality of disease diagnosis codes according to the plurality of correlation degree scores, to generate an initial list, and executes the post-processing module to post-process the initial list according to a preset coding rule. The processor generates a recommendation list according to the post-processed initial list.
