  1. All percentages use the whole population as denominator and are not specific to payer (e.g., Special Medicaid Services for Medicaid). Examples of special Medicaid services include patients receiving day treatment, residential treatment, case management services, and special school services covered by the Department of Education. Clinical Risk Groups utilize a hierarchy to classify a patient into one and only one CRG for the year. Example conditions include Acute or Minor Chronic (e.g., acute ear, nose or throat condition or minor join pain), Moderate Chronic (e.g., diabetes or moderate chronic joint pain), Significant Chronic (e.g., diabetes with other comorbid conditions such as CHF or COPD), and Cancer or Catastrophic (e.g., malignant breast cancer, HIV, cystic fibrosis, muscular dystrophy, quadriplegia). Target Conditions include asthma, chronic obstructive pulmonary disease, congestive heart failure, ischemic heart disease, hypertension, depression, diabetes, and attention deficit disorder
