MS-DRG 922, Other Injury, Poisoning and Toxic Effect Diagnoses with MCC, is a medical DRG in MDC 21 (Injuries, Poisonings and Toxic Effects of Drugs) under MS-DRG version 44.0, which applies to inpatient discharges from October 1, 2026 through September 30, 2027.

Its FY2027 relative weight is 1.6238, so Medicare's base payment for this DRG is about 1.62 times the average inpatient case, before hospital-specific adjustments. The geometric mean length of stay is 3.9 days and the arithmetic mean is 6.3 days.

It belongs to a 2-level severity family: DRG 922 (with MCC, weight 1.6238) and DRG 923 (without MCC, weight 0.9973). The highest-severity level carries 1.6 times the weight of the lowest, which is why documenting CC and MCC conditions matters.

2,446 ICD-10-CM diagnosis codes are part of this DRG's grouping logic; they are listed below.
