8 The denominator is $ 2. In the disease interactions and disabled interactions, the variables are defined as follows: Sepsis = HCC 2. Opportunistic Infections = HCC 6. Cancer = HCCs 8-12. Diabetes = HCCs 17, 18, 19. Bone/Joint/Muscle Infections/Necrosis = HCC 39. Immune Disorders = HCC 47. Schizophrenia = HCC 57. Multiple Sclerosis = HCC 77. Seizure Disorders and Convulsions = HCC 79. Cardiorespiratory Failure = HCCs 82-84. Congestive Heart Failure = HCC 85. Chronic Obstructive Pulmonary Disease = HCCs 110-111. Aspiration and Specified Bacterial Pneumonias = HCC 114. Renal Disease = HCCs 134-137.

9 Pressure Ulcer = HCCs 157-158. HCCs 159-160 are no longer included in the pressure ulcer interaction terms. Chronic Ulcer of Skin, except Pressure = HCC 161. Artificial Openings for Feeding or Elimination = HCC 188.

For payment purposes, a new enrollee is a beneficiary who did not have 12 months of Part B eligibility in the data collection year. CMS-HCC new enrollee models are not based on diagnoses, but include factors for different age and gender combinations by Medicaid and the original reason for Medicare entitlement. 2.
