Abstract: The exemplary embodiments disclose a system and method, a computer program product, and a computer system for assigning medical codes. The exemplary embodiments may include receiving a medical record in machine-readable text-form, wherein the medical record comprises at least one treatment, converting a portion of the medical record into a determined first medical code of a first length, querying a knowledge graph comprising medical records and a coding catalog for a second medical code of higher order than the first medical code, wherein the second medical code relates to the first medical code, and searching evidence in the medical record for the second medical code by comparing at least a portion of clear text relating to the second medical code with the medical record.

Abstract: The exemplary embodiments disclose a system and method, a computer program product, and a computer system for assigning medical codes. The exemplary embodiments may include receiving a medical record comprising a diagnosis code, querying a knowledge graph using the diagnosis code, the knowledge graph comprising as nodes: case identifiers, diagnosis codes and related procedure codes, and secondary diagnosis codes and related secondary procedure codes, wherein edges between the nodes are indicative of a type of relationship between related nodes derived from real past medical records, and receiving, based on the query, a ranked list of the diagnosis codes, related procedure codes, and secondary diagnosis codes and the related secondary procedure codes based on relative occurrences of the past medical records.
