About MS-DRG 827
MS-DRG 827, Myeloproliferative Disorders or Poorly Differentiated Neoplasms with Major O.R. Procedures with CC, is a surgical DRG in MDC 17 (Myeloproliferative Diseases and Disorders, Poorly Differentiated Neoplasms) under MS-DRG version 44.0, which applies to inpatient discharges from October 1, 2026 through September 30, 2027.
Its FY2027 relative weight is 2.3896, so Medicare's base payment for this DRG is about 2.39 times the average inpatient case, before hospital-specific adjustments. The geometric mean length of stay is 3.9 days and the arithmetic mean is 5.1 days.
It belongs to a 3-level severity family: DRG 826 (with MCC, weight 4.7581), DRG 827 (with CC, weight 2.3896) and DRG 828 (without CC/MCC, weight 1.6955). The highest-severity level carries 2.8 times the weight of the lowest, which is why documenting CC and MCC conditions matters.
114 ICD-10-CM diagnosis codes are part of this DRG's grouping logic; they are listed below.
