Patent granted for mapping icd-9/10 codes to snomed ct concepts
A recently granted patent (Publication Number: US11960456B1) discloses a computing device designed to automate clinical concept mapping using SNOMED CT (Systematized Nomenclature of Medicine Clinical Terms). The device, equipped with processors and memory devices, executes instructions to map ICD-9 and ICD-10 codes to SNOMED CT concepts, generate a directed acyclic graph (DAG) of these concepts, identify unpaired codes, determine semantic similarity between clinical descriptions, and pair codes based on common concepts and similarity. The patent also includes the use of a neural network for semantic similarity identification, obtaining mappings from external systems like OMOP, and rolling up multiple ICD codes into a single SNOMED concept using the DAG.
Furthermore, the patent details a method for automated clinical concept mapping, emphasizing the identification of unpaired codes, determination of semantic similarity, and pairing based on common concepts. The method involves utilizing pivot nodes in the DAG for linking queries and targets, identifying ancestors within a minimum separation distance, and includes ICD-9, ICD-10, or ICD-X (where X is a variable) codebases. Additionally, computer-readable media storing instructions for the computing device to execute the mapping process, search for pairings in both directions, reduce entries in pairing tables, and produce output tables supporting ETL functionality are also covered in the patent. Overall, the patent aims to streamline the mapping of clinical codes, enhance interoperability, and improve the efficiency of healthcare data management systems.
