About MS-DRG 202
MS-DRG 202, Bronchitis and Asthma with CC/MCC, is a medical DRG in MDC 04 (Diseases and Disorders of the Respiratory System) under MS-DRG version 44.0, which applies to inpatient discharges from October 1, 2026 through September 30, 2027.
Its FY2027 relative weight is 0.9474, so Medicare's base payment for this DRG is about 0.95 times the average inpatient case (below average), before hospital-specific adjustments. The geometric mean length of stay is 2.8 days and the arithmetic mean is 3.5 days.
It belongs to a 2-level severity family: DRG 202 (with CC/MCC, weight 0.9474) and DRG 203 (without CC/MCC, weight 0.6512). The highest-severity level carries 1.5 times the weight of the lowest, which is why documenting CC and MCC conditions matters.
47 ICD-10-CM diagnosis codes are part of this DRG's grouping logic; they are listed below.
