Don't overlook a valuable resource in making your transition to the ICD-10 diagnosis coding system. CMS and the Centers for Disease Control and Prevention have issued "General Equivalence Mappings" or GEMS, the agencies remind providers. "You can look up an ICD-9 code and be provided with the most appropriate ICD-10 matches and vice versa," CMS explains in an e-mail message to providers. "They are not a substitute for learning the new ICD-10 codes; however, they can assist users" with various coding functions. Links to the GEMs for 2010 and 2011 are at www.cms.gov/ICD10. Reminder: ICD-9 will undergo a code freeze starting Oct. 1. "This is the last day for regular updates to both the ICD-9 and ICD-10 code sets," CMS explains. "Starting Oct. 1, 2012 there will be only limited code updates to ICD-9-CM and ICD-10 code sets to capture new technology and new diseases." Deadline: ICD-10 will take effect in October 2013 (see related story, p. 165).
