Hypertension with Major Complication or Comorbidity: Inpatient Reimbursement Overview
DRG 304 addresses inpatient admissions for hypertension accompanied by a Major Complication or Comorbidity, reflecting increased clinical complexity and resource needs. Correct grouping impacts inpatient reimbursement under Medicare because payment is adjusted based on severity levels captured by the Diagnosis-Related Group.
DRG 304 Overview
DRG 304—Hypertension with Major Complication or Comorbidity—covers inpatient stays where primary or secondary hypertension is present alongside one or more Major Complication or Comorbidity conditions that increase resource use and clinical complexity. This Diagnosis-Related Group captures admissions requiring intensified monitoring, additional diagnostic workup, or treatment for severe hypertensive complications such as hypertensive crisis with end-organ effects or acute cardiovascular events. It matters for Medicare payment because classification into DRG 304 affects relative reimbursement levels tied to case severity and expected resource consumption. Accurate documentation and coding of the hypertension diagnosis and any Major Complication or Comorbidity are essential for correct grouping and payment assignment.
