Abstract
Disclosed herein is a system which address the problem of multiple mappings of a source ICD code to a target ICD code by using an adaptive mechanism to automatically convert to a target ICD code with the help of accompanying data and associated rules. The mechanism is based on analysis of the ICD code description, and analysis of accompanying data to determine a set of parameters to assist in the conversion. The rules are assigned numerical values to indicate the confidence of conversion. An adaptive mechanism is also disclosed that automatically tracks user overrides to refine the rules and the indicator values over time.
Claims35
A computer-implemented method for a probabilistic target mapping of a source International Classification of Diseases (ICD) code to one or more target ICD codes, the method comprising:
- generating scenario tokens, supplementary tokens and identifier tokens from the target ICD codes descriptions, wherein multiple equivalent target ICD codes descriptions correspond to a source ICD code;
- calculating an attribute score for each of:
- a. at least one of a scenario, wherein the at least one of a scenario is determined by comparing the scenario tokens with a set of configured parameters;
- b. at least one of a choice list determined using supplementary tokens;
- and
- c. at least one of the choice list determined using identifier tokens;
- calculating a total code score for each of the target ICD codes descriptions;
- and
- generating a probabilistic target ICD code based on the total code score.
An automated system for a probabilistic target mapping of a source International Classification of Diseases (ICD) code to one or more target ICD codes, the system comprising:
- a token generating module for generating scenario tokens, supplementary tokens and identifier tokens from the target ICD codes descriptions, wherein multiple equivalent target ICD codes descriptions correspond to a source ICD code;
- a processor configured to calculate an attribute score for each of:
- a. at least one of a scenario, wherein the at least one of a scenario is determined by comparing the scenario tokens with a set of configured parameters;
- b. at least one of a choice list determined using supplementary tokens;
- and
- c. at least one of the choice list determined using identifier tokens;
- calculate a total code score for each of the equivalent target ICD codes;
- and
- a code generator module for generating a probabilistic target ICD code based on the total code score.
