The changes are intended to address higher rates of coding of some HCCs by MAOs compareed to FFS providers. If implemented, the number of HCCs will increase from 70 to 79 and CMS plans to recalibrate the model.
This will cause a reduction in the value of a number of HCCs. CMS is proposing a phased-in implementation of the new model over a multi-year period. For 2014, CMS would implement coefficients of the revised model but would transition over a multi-year period to the revised model denominator.
Final provisions will be released on April 1, 2013, and we will post them as soon as possible. You can review the Advance Notice and Proposed Model Diagnoses on HCCUniversity.com.
