Overview: This paper examines bias in Medicare Principal Impatient Diagnostic Cost Group model due to unobserved selection using HMO and FFS hospital use data. The objective of this dissertation is to determine whether the principal inpatient diagnostic cost group (PIP-DCG) model adequately adjusts for HMO (health maintenance organization) favorable selection, and, if not, to quantify the model's bias in predicting resource use of HMO enrollees that is due to unobserved selection.
