What You Should Know About the GEMS and Partial Code Freeze
INDUSTRY NEWS TAGS: CMS
The GEMs are tools that act mainly as a crosswalk between the ICDÃ±9 and ICDÃ±10 codes. CMS and the Centers for Disease Control and Prevention (CDC) created the national version of the GEMs to ensure that consistency in national data is maintained. You can look up an ICDÃ±9 code and be provided with the most appropriate ICDÃ±10 matches and vice versa. They are not a substitute for learning the new ICDÃ±10 codes; however, they can assist users doing the following:
• Translating lists of codes, code tables, or other coded data
• Converting a system or application containing ICDÃ±9Ã±CM codes
• Creating a "one-to-one" applied mapping (aka crosswalk) between code sets that will be used in an ongoing way to translate records or other coded data
• Studying the differences in meaning between the ICDÃ±9Ã±CM classification systems and the ICDÃ±10-CM/PCS classification systems by looking at the GEMs entries for a given code or area of classification
The 2011 GEMs are posted to the CMS ICDÃ±10 website. As a reminder, if you plan to use a GEM, per the Affordable Care Act, you must use the GEMs posted to the CMS website.
Because continuous updates and changes to the existing code sets has the potential to make the transition to ICDÃ±10 difficult, CMS will be implementing a partial code freeze on October 1, 2011. This is the last day for regular updates to both the ICD-9 and ICDÃ±10 code sets. Starting October 1, 2012 there will be only limited code updates to ICDÃ±9Ã±CM and ICDÃ±10 code sets to capture new technology and new diseases. There will be no updates to ICDÃ±9Ã±CM on October 1, 2013 as the system will no longer be a HIPAA standard.
