063 — Ischemic Stroke, Precerebral Occlusion or Transient Ischemia with Thrombolytic Agent without CC/MCC

MS-DRG 063, Ischemic Stroke, Precerebral Occlusion or Transient Ischemia with Thrombolytic Agent without CC/MCC, is a medical DRG in MDC 01 (Diseases and Disorders of the Nervous 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 1.455, so Medicare's base payment for this DRG is about 1.46 times the average inpatient case, before hospital-specific adjustments. The geometric mean length of stay is 2.2 days and the arithmetic mean is 2.4 days.

It belongs to a 3-level severity family: DRG 061 (with MCC, weight 2.7211), DRG 062 (with CC, weight 1.7781) and DRG 063 (without CC/MCC, weight 1.455). The highest-severity level carries 1.9 times the weight of the lowest, which is why documenting CC and MCC conditions matters.

130 ICD-10-CM diagnosis codes are part of this DRG's grouping logic; they are listed below.
