What methodology is being used in the MS-DRG ICD-10 conversion?
The goal of MS-DRG ICD-10 conversion is to replicate the current MS-DRG logic. A record coded in ICD-10-CM/PCS and processed according to the converted ICD-10-based MS-DRGs will be assigned to the same MS-DRG as the same record coded in ICD-9-CM and processed according to the current MS-DRG logic.We are accomplishing this goal by translating the lists of ICD-9-CM codes that comprise the MS-DRGs (approximately 500 code lists) to comparable lists of ICD-10-CM/PCS codes without changing the underlying MS-DRG logic. This method of replacing lists of ICD-9-CM codes with lists of ICD-10 codes is partially automated using the GEMs. 8. When do you anticipate that an ICD-10 version of the MS-DRGs will be completed and posted on the CMS website? A draft ICD-10 version of the MS-DRGs will be completed in October 2009. We will format this ICD-10 version of the MS-DRGs and post it in January 2010 along with the 2010 updates to ICD-10 and the GEMs in the Downloads Section at http://www.cms.hhs.gov/I
