DRG 981 Overview
DRG 981 covers hospital stays involving extensive operating room procedures that are unrelated to the principal diagnosis and that include a Major Complication or Comorbidity. These cases typically involve significant additional surgical intervention occurring during the same inpatient episode, increasing resource use and clinical complexity. This Diagnosis-Related Group matters for Medicare payment because the presence of a Major Complication or Comorbidity elevates reimbursement to reflect higher expected costs of care. Accurate coding of procedures and comorbid conditions is critical to align payment with the intensity of services provided.
