2011 versions of the ICD-10-CM crosswalks now available

CMS has posted the 2011 versions of the ICD-10-CM and ICD-10-PCS crosswalks, formally referred to as the General Equivalence Mappings (GEMs), on the ICD-10 website at https://www.cms.gov/ICD10. These updated files complete the requirements of the Affordable Care Act of 2010. The Affordable Care Act required the Secretary of Health and Human Services to task the ICD-9-CM Coordination and Maintenance Committee to convene a meeting before January 1, 2011, to receive stakeholder input regarding the crosswalks between ICD-9-CM and ICD-10 for the purpose of making appropriate revisions to said crosswalks. These revisions to the crosswalks are posted to the CMS website and treated as a code set for which the Secretary has adopted a standard. In addition, CMS also has posted ICD-10 GEMs 2011 Version Update, Update Summary. This document describes the number of comments we received, the type of changes recommended, the types of changes made based on the comments, and the types of comments not accepted and reasons why some comments were not accepted.
