Summary & Overview
Respiratory Infections and Inflammations with MCC: Inpatient Reimbursement Overview
177 encompasses high-acuity respiratory infections and inflammations with Major Complication or Comorbidity affecting inpatient resource use. This DRG matters for inpatient reimbursement because the presence of an MCC increases payment relative to lower-severity respiratory DRGs, reflecting greater expected cost and intensity of care.
DRG 177 Overview
Diagnosis-Related Group (DRG) 177 covers hospital admissions for respiratory infections and inflammations complicated by at least one Major Complication or Comorbidity (MCC), typically including severe pneumonias, empyema, or acute exacerbations with organ dysfunction. This DRG groups high-acuity respiratory cases that drive greater resource use, longer lengths of stay, and higher Medicare Severity Diagnosis-Related Group (MS-DRG) payments. Accurate coding of the primary respiratory diagnosis and accompanying MCCs is central to determining payment under Medicare. The classification affects hospital reimbursement levels and case mix index calculations.
National Payment Rates
Mean rates across payers range from $13,857.32 for Medicare to $26,389.61 for Aetna, with a wide absolute spread of $12,532.29 across the full set of payers. Commercial payers such as Aetna, Cigna, and Anthem cluster near the mid-to-high $20,000s while BCBS and BUCA sit lower, contributing to the widest variability. See the table and chart below for payer-specific quartiles and means.
