DRG 326 Overview
DRG 326 covers inpatient admissions for major stomach, esophageal, and duodenal procedures when a Major Complication or Comorbidity is present. Cases typically involve complex surgical interventions such as gastrectomy, esophagectomy, or extensive duodenal surgery with significant perioperative resource use. This Diagnosis-Related Group matters for Medicare payment because the presence of a Major Complication or Comorbidity increases the relative resource intensity and reimbursement weight compared with lower-severity groups. Accurate coding of procedures and comorbid conditions is essential to assign the appropriate Medicare Severity Diagnosis-Related Group and reflect expected inpatient costs.
