DRG 146 Overview
DRG 146 covers inpatient admissions for malignant neoplasms of the ear, nose, mouth, and throat with Major Complication or Comorbidity present. Typical cases include complex head and neck cancer surgeries, extensive resections, or major complications requiring intensive management. This Diagnosis-Related Group drives higher Medicare reimbursement because the presence of a Major Complication or Comorbidity substantially increases resource use and length of stay. Accurate coding of the primary tumor site, procedures, and accompanying Major Complication or Comorbidity is central to payment assignment.
