      group's case mix index and reimbursement.
PG  - 1001-11
AB  - The Health Care Finance Administration has developed a Medicare reimbursement 
      methodology that will include an adjustment factor for hospital case mix. The 
      patient classification scheme proposed for use in determining a hospital's case 
      mix is the AUTOGRP Diagnosis-Related Groups (DRG) methodology developed at Yale 
      University. The reliability of a case mix measure calculated using the DRG 
      methodology is dependent on complete and accurate diagnostic and surgical data. 
      The source of this data for the HCFA data base (MEDPAR) is the Medicare billing 
      form, which is based on the patient medical record. Data from the MEDPAR file, 
      the original medical record discharge order, and a reabstracted record are 
      compared and analyzed for their effect upon DRG classification and the resultant 
      Medicare reimbursement ceiling for one large teaching hospital. The study results 
      show widely divergent diagnostic and surgical data that results in a significant 
      variation in DRG classification and reimbursement ceilings.
