Classification tree considering age, gender, and diagnosis and drug codes for CRGs 1000-5424-6144-7071. Clinicians can easily separate patients belonging to CRG-1000 from the rest based on the diagnostic code ‘250’, since its absence identifies healthy individuals. However, its presence in conjunction with the absence of codes ‘401’, ‘496’ and ‘N05AL’ leads to patients in CRG-5424. The presence of the last three codes identifies patients in CRGs 6144 and 7071
