DRG 603 Overview
DRG 603 covers hospital admissions for cellulitis without Major Complication or Comorbidity and represents cases where the infection is managed medically without higher-severity secondary diagnoses. This Diagnosis-Related Group is focused on skin and soft tissue infection treatment, often involving intravenous antibiotics and observation for systemic signs. It matters for Medicare payment because the assigned Diagnosis-Related Group determines the inpatient prospective payment and influences resource use classification for Centers for Medicare & Medicaid Services billing. Accurate capture of clinical complexity affects grouping into DRG 603 versus higher-paying Diagnosis-Related Groups.
