Compared to the ICD-10-PCS index, the ICD-9-CM Procedure (ICD9V3) Index is richer and contains more clinician-friendly terms including abbreviations and eponyms. We re-purposed the ICD9V3 index by mapping the index terms to SNOMED CT and the ICD-9-CM codes to ICD-10-PCS codes through the General Equivalent Mappings. The re-purposed index outperformed the ICD-10-PCS index in the retrieval of ICD-10-PCS codes using a list of commonly used procedure names, with significantly higher recall, precision and F-score. We also derived a SNOMED CT to ICD-10-PCS map from the re-purposed ICD-9-CM index, which had a higher coverage of SNOMED CT concepts and comparable accuracy compared to a map derived from the ICD-10-PCS index. The re-purposed index will be a useful resource for ICD-10-PCS coders and for mapping between SNOMED CT and ICD-10-PCS.
与ICD - 10 - PCS索引相比，ICD - 9 - CM手术（ICD9V3）索引内容更丰富，包含更多对临床医生友好的术语，包括缩写和人名/地名等专用名称。我们通过通用等效映射将索引术语映射到SNOMED CT，并将ICD - 9 - CM编码映射到ICD - 10 - PCS编码，从而对ICD9V3索引进行了重新利用。在使用常用手术名称列表检索ICD - 10 - PCS编码时，重新利用后的索引表现优于ICD - 10 - PCS索引，召回率、精确率和F值显著更高。我们还从重新利用后的ICD - 9 - CM索引中得出了一个从SNOMED CT到ICD - 10 - PCS的映射，与从ICD - 10 - PCS索引得出的映射相比，该映射对SNOMED CT概念的覆盖范围更大且准确性相当。重新利用后的索引将成为ICD - 10 - PCS编码人员以及SNOMED CT与ICD - 10 - PCS之间映射的有用资源。
