Disorders of Liver Except Malignancy, Cirrhosis or Alcoholic Hepatitis with CC: Inpatient Reimbursement Overview
DRG 442 includes nonmalignant liver disorders excluding cirrhosis and alcoholic hepatitis when a Complication or Comorbidity is present, encompassing acute hepatic conditions and related procedures. It matters for inpatient reimbursement because the Complication or Comorbidity designation raises expected resource use and therefore impacts Medicare payment under the prospective payment system.
DRG 442 Overview
DRG 442 covers inpatient cases for disorders of the liver excluding malignancy, cirrhosis, or alcoholic hepatitis when a Complication or Comorbidity is present. Typical diagnoses include acute hepatic dysfunctions, biliary disorders, and nonmalignant hepatic necrosis that require inpatient medical or procedural management. This Diagnosis-Related Group matters for Medicare payment because the presence of a Complication or Comorbidity elevates resource intensity and influences the prospective payment amount. Accurate assignment affects hospital reimbursement, coding audit risk, and case-mix index calculations.
