DRG 397 Overview
DRG 397 covers inpatient admissions for patients undergoing appendix procedures when a Major Complication or Comorbidity is present. Typical cases include appendectomy or appendiceal drainage with significant comorbid conditions or complications that increase resource use. This Diagnosis-Related Group matters for Centers for Medicare & Medicaid Services payment because the presence of a Major Complication or Comorbidity increases the relative severity and reimbursement weight. Hospitals and coders must accurately capture operative and secondary diagnosis detail to align claims with appropriate inpatient reimbursement.
