Abstract Objective ICD-10, the basic data standard for diagnosis related groups (DRG), will be gradually replaced by ICD-11 starting from 2022. This paper studies ICD-11′s support for DRG, which is beneficial to the construction of grouping scheme and provides guidance for disease coding. Methods Three mapping tables from ICD-10 clinical modification to ICD-11 were established to replace the definition of CN-DRG diagnostic code respectively, and three new DRG groupers were formed to replace the ICD-10 coding data in the first page of medical records respectively. The new groupers were used to group for analysis and comparison. Results Before and after the conversion of single mapping, the number of enrolled cases was equal, with 3 206 229 cases; the number of enrolled DRG groups was equal, with 780 cases; the number of enrolled cases in each DRG group was equal. After using the cluster code mapping conversion, the number of the groups in which cases changed was 722, and the enrollment rate decreased to 98.1%; after using the stem code mapping conversion, the number of the groups in which cases changed was 746, and the enrollment rate decreased to 97.1%. Conclusion CN-DRG can support DRG grouping of the first page data of ICD-11 diagnostic code based on mapping; in order to better meet the DRG grouping requirements, the current ICD-11 coding needs to be further refined.
