The TREC 2012 Medical Records Track task involves the identification of electronic medical records EMRs that are relevant to a set of search topics. Atigeo has a Computer-Aided Coding CAC product that analyzes electronic medical records EMRs and recommends ICD-9 codes that represent the diagnoses and procedures described in those medical records. We have developed a suite of natural language processing NLP components that are useful for both tasks. Our TREC 2012 experiments focused on the ICD-9 admission and diagnosis codes included in more than 90 of the TREC EMRs we used our comprehensive ICD-9 database to insert one of three variants of the text descriptions associated with each code found in each EMR. We describe the variations of ICD-9 code descriptions we inserted, the NLP components used for processing all the reports and topics, and report on the results of our experiments.
