About MS-DRG 436
MS-DRG 436, Malignancy of Hepatobiliary System or Pancreas with CC, is a medical DRG in MDC 07 (Diseases and Disorders of the Hepatobiliary System and Pancreas) under MS-DRG version 44.0, which applies to inpatient discharges from October 1, 2026 through September 30, 2027.
Its FY2027 relative weight is 1.1224, so Medicare's base payment for this DRG is about 1.12 times the average inpatient case, before hospital-specific adjustments. The geometric mean length of stay is 3.3 days and the arithmetic mean is 4.2 days.
It belongs to a 3-level severity family: DRG 435 (with MCC, weight 1.843), DRG 436 (with CC, weight 1.1224) and DRG 437 (without CC/MCC, weight 0.8081). The highest-severity level carries 2.3 times the weight of the lowest, which is why documenting CC and MCC conditions matters.
