Matthew Fiedler commented on the risk adjustment provisions of the 2024 Medicare Part C and D Advance Notice published by the Centers for Medicare and Medicaid Services (CMS).

He also says that CMS’ proposals to exclude from the model certain diagnoses that are more intensively coded in MA (or limit the role of those diagnoses) have advantages over other ways of addressing higher coding intensity in MA; however, CMS should be attentive to the risk of reducing the model’s predictive power and report how the changes affect measures of model fit, such as the model R².
