Abstract: Techniques are provided for candidate screening for a target therapy. A plurality of medical codes corresponding to patient billing data are identified. A candidate classification model for a target therapy is generated by selecting a set of medical codes from the plurality of medical codes and assigning a weight to each medical code selected. The candidate classification model is applied to patient billing data for a plurality of patients to generate a set of target therapy scores. The patient billing data includes associations between one or more patients of the plurality of patients and one or more medical codes of the plurality of medical codes. Each target therapy score corresponds to a patient of the plurality of patients, and is calculated based on weights for one or more medical codes associated with the patient.
