Implementation of ICD-10-CM/PCS remains three years away. But it is not too soon to find out more about the data set. On Thursday, November 19, from 12:30-2 p.m. (EST), CMS plans to hold a National Provider Conference Call to discuss the conversion of ICD-9 to ICD-10.
The outreach call will describe the preliminary exercise CMS undertook to convert data using the General Equivalence Mappings (GEM), according to the announcement. The GEMs are a tool developed to assist CMS and other data users who need to convert ICD-9-CM data or payment systems to the relevant ICD-10-CM/PCS codes and
ICD-10-CM/PCS codes back to the relevant ICD-9-CM codes.
The following topics will be discussed during the conference call:
  • How ICD-9-CM based Medicare Severity-Diagnosis Related Group (MS-DRGs), version 26.0, were converted to ICD-10-CM and ICD-10-PCS codes
  • The best way to use the GEMs in converting data
According to a related Q&A on the CMS Web site a draft ICD-10 version of the MS-DRGs was completed in October 2009, and will be posted in January 2010 along with the 2010 updates to ICD-10 and the General Equivalence Mappings. CMS says it “welcome[s] recommendations regarding how this information should be displayed. [because it] believe[s] this exercise will provide useful information to other payers who will be converting their own payment systems.
