Summary & Overview
Reticuloendothelial and Immunity Disorders with MCC: Inpatient Reimbursement Overview
DRG 814 covers serious reticuloendothelial and immune system disorders coded with a Major Complication or Comorbidity, representing higher-acuity admissions that drive greater resource use. Understanding this Diagnosis-Related Group is important for inpatient reimbursement because Major Complication or Comorbidity status affects relative weights and payment determination under Medicare.
DRG 814 Overview
DRG 814 (Reticuloendothelial and Immunity Disorders with Major Complication or Comorbidity) encompasses inpatient admissions for serious disorders of the reticuloendothelial system and immune function that include at least one Major Complication or Comorbidity. Typical cases involve severe immune dysregulation, hematologic immune disorders, severe infections with immune compromise, or complications of immunotherapy requiring substantial resource use. This Diagnosis-Related Group matters for Medicare payment because the presence of a Major Complication or Comorbidity elevates relative weights and payment levels to reflect higher intensity of care and longer hospital stays. Accurate clinical documentation and coding determine assignment to this Diagnosis-Related Group and thus influence inpatient reimbursement.
