We are pleased to announce the release of revised versions of the Combined Chronic Illness and Pharmacy Payment System (CDPS+Rx) and the Medicaid Rx (MRX) risk adjustment models. These new models (Version 6.1) are available to license on a nonexclusive basis. Please contact the Office of Innovation and Commercialization for additional information about licensing.

Synopsis: The authors describe the diversity of diagnoses and different burdens of illness among disabled and AFDC Medicaid beneficiaries. Claims from seven states were analyzed which provided payment weights that states can use when adjusting HMO payments. The taxonomy and statistical performance of CDPS were compared to other leading diagnostic classification systems, and the findings suggest that the new model performs better in a number of respects.
