About MS-DRG 159
MS-DRG 159, Dental and Oral Diseases without CC/MCC, is a medical DRG in MDC 03 (Diseases and Disorders of the Ear, Nose, Mouth and Throat) under MS-DRG version 44.0, which applies to inpatient discharges from October 1, 2026 through September 30, 2027.
Its FY2027 relative weight is 0.6893, so Medicare's base payment for this DRG is about 0.69 times the average inpatient case (below average), before hospital-specific adjustments. The geometric mean length of stay is 2 days and the arithmetic mean is 2.5 days.
It belongs to a 3-level severity family: DRG 157 (with MCC, weight 1.809), DRG 158 (with CC, weight 0.9366) and DRG 159 (without CC/MCC, weight 0.6893). The highest-severity level carries 2.6 times the weight of the lowest, which is why documenting CC and MCC conditions matters.
415 ICD-10-CM diagnosis codes are part of this DRG's grouping logic; they are listed below.
