This section provides information on the project for using the General Equivalence Mappings (GEMs) to convert the draft MS-DRGs to ICD-10-CM and ICD-10-PCS. Information is also provided on undertaking a similar conversion project.
The draft ICD-10-CM/PCS MS-DRG V32 Definitions Manual and Medicare Code Editor (MCE) V32 are provided below along with the previous ICD-10 ICD-10-CM/PCS MS-DRG V31R Definitions and MCEs. The text version is under the “Downloads” section and the HTML version is under the "Related Links" section in with full title formats. Version 32 (V32) was developed after reviewing public comments on the previously posted Version 31R.
The Final ICD-10 MS-DRG v33 logic which will be implemented on October 1, 2015 will be subject to rulemaking.
