Although we have not had time to analyze the notice in detail, CMS is proposing not to implement the new model that was proposed for Part C for 2012 in order to minimize changes during 2012.
Based on the proposal released on Friday, there will be no changes to the CMS-HCC Model for 2012. CMS will not implement previously proposed changes (e.g. addition of dementia and morbid obesity) until 2013 at the earliest, unless they change what is in the Advance Notice. We will know with certainty on April 4, 2011 when the Announcement is published, but at this time, it is extremely unlikely that the model will change in 2012.
