DRG 331 Overview
DRG 331 covers inpatient admissions for major small and large bowel surgical procedures when no Complication or Comorbidity and no Major Complication or Comorbidity are present. Typical cases include resections, anastomoses, or other significant bowel operations performed without documented additional complicating diagnoses. This Diagnosis-Related Group matters because it groups cases of moderate surgical complexity into a standardized Medicare payment category that informs hospital reimbursement. Accurate clinical coding and documentation determine assignment to DRG 331 and thus affect payment.
