This is a comprehensive list of all the MCCs that were made effect as a result of the implementation of the MS-DRGs.  No ICD-9-CM codes are in this list.  Only an extended description of each code is included.  A key feature of this list is that it is alphabetized for easy reference.  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. It is formatted to be stored in a three ring binder.
