This is a comprehensive list of all the CCs that were made effect as a result of the implementation of the MS-DRGs.  Both the ICD-9-CM code number (with decimals) and an extended description of each code is included.  A key feature of this list is that bold formatting is applied to each CCs that was added as a result of the new MS-DRG system while the CCs that were already in effect are in regular font.  This list is also categorized where appropriate to make it more user-friendly and less cumbersome than if every single code is listed out separately.
