Free ICD-10 to ICD-9 Crosswalk (GEMs)

ICD-9 diagnosis codes will be phased out in 2015, and will be replaced by ICD-10 codes. This crosswalk tool based on the Centers for Medicare and Medicaid (CMS) 2015 General Equivalency Mapping (GEMS) facilitates the translation between ICD-10 codes and the new ICD-9 code set. Please keep in mind that this crosswalk tool is meant to be used in conjunction with the official ICD publications in order to ensure that the most appropriate code(s) are used for every particular situation.
