About MS-DRG 392
MS-DRG 392, Esophagitis, Gastroenteritis and Miscellaneous Digestive Disorders without MCC, is a medical DRG in MDC 06 (Diseases and Disorders of the Digestive 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 0.7645, so Medicare's base payment for this DRG is about 0.76 times the average inpatient case (below average), before hospital-specific adjustments. The geometric mean length of stay is 2.5 days and the arithmetic mean is 3.1 days.
It belongs to a 2-level severity family: DRG 391 (with MCC, weight 1.2392) and DRG 392 (without MCC, weight 0.7645). The highest-severity level carries 1.6 times the weight of the lowest, which is why documenting CC and MCC conditions matters.
250 ICD-10-CM diagnosis codes are part of this DRG's grouping logic; they are listed below.
