Summary & Overview
Infectious and Parasitic Diseases with O.R. Procedures without CC/MCC: Inpatient Reimbursement Overview
DRG 855 groups inpatient cases for infectious and parasitic diseases that required operating room procedures without Complication or Comorbidity or Major Complication or Comorbidity, reflecting the clinical focus on operative management of infection. This classification matters for inpatient reimbursement because it determines payment relative to resource intensity and coding specificity under Medicare payment rules.
DRG 855 Overview
DRG 855 covers hospital admissions for infectious and parasitic diseases that require operating room procedures and do not involve a Complication or Comorbidity or a Major Complication or Comorbidity. Typical cases include surgical management of severe infections such as abscess drainage or debridement for necrotizing soft tissue infections where no additional coded complications are present. This Diagnosis-Related Group groups inpatient stays by resource use tied to operative infectious disease management and directly affects Medicare payment assignment and hospital billing classification.
