616 — Amputation of Lower Limb for Endocrine, Nutritional and Metabolic Disorders with MCC or Insertion of Antibiotic-eluting Bone Void Filler

MS-DRG 616, Amputation of Lower Limb for Endocrine, Nutritional and Metabolic Disorders with MCC or Insertion of Antibiotic-eluting Bone Void Filler, is a surgical DRG in MDC 10 (Endocrine, Nutritional and Metabolic Diseases and Disorders) under MS-DRG version 44.0, which applies to inpatient discharges from October 1, 2026 through September 30, 2027.

Its FY2027 relative weight is 3.1453, so Medicare's base payment for this DRG is about 3.15 times the average inpatient case, before hospital-specific adjustments. The geometric mean length of stay is 8.3 days and the arithmetic mean is 10.4 days.

It belongs to a 3-level severity family: DRG 616 (with MCC or Insertion of Antibiotic-eluting Bone Void Filler, weight 3.1453), DRG 617 (with CC, weight 1.7227) and DRG 618 (without CC/MCC, weight 1.2765). The highest-severity level carries 2.5 times the weight of the lowest, which is why documenting CC and MCC conditions matters.

It is subject to Medicare's post-acute care transfer policy, so payment can be reduced when a patient with a shorter-than-average stay is discharged to a skilled nursing facility, home health or another post-acute setting.
