The purpose of this study is to examine the relationship between the diagnosis and the cost of patient care for those with diabetes in Medicare. In this analysis, the author used data sets about outpatient claim, inpatient claim as well as beneficiary demography information for the year 2004, all of which were taken from the Chronic Condition Data Warehouse provided by the Centers for Medicare and Medicaid. The author analyzed the cases for diabetic inpatients and outpatients by different methods. For outpatient analysis, exploratory data analysis and linear models were used .The results show that the total charges for diagnoses are reduced considerably for payment. The distribution of the total charges follows a Gamma distribution. The output of the generalized linear model demonstrates that only 15 out of the top 20 primary treatments for charges are statistically significant to the expenditures on outpatients.
