MS-DRG 393 – Other Digestive System Diagnoses with MCC
A Medical DRG in MDC 06 (Diseases & Disorders of the Digestive System). Inpatient cases group to DRG 393 when the ICD-10-CM principal diagnosis is one of the 575 codes listed below and a secondary diagnosis on the major complication or comorbidity (MCC) list is present. Its FY 2026 relative weight is 1.5993 with a geometric mean length of stay of 4.2 days.

How a case is assigned to DRG 393
The grouper first assigns the case to MDC 06 from the principal diagnosis and finds no qualifying operating-room procedure (this is a Medical DRG; ICD-10-PCS codes do not drive assignment here), then applies the severity split from secondary diagnoses: with MCC → 393; with CC → 394; without CC/MCC → 395.

Frequently Asked Questions
What is MS-DRG 393?
MS-DRG 393 (Other Digestive System Diagnoses with MCC) is a medical DRG in MDC 06 (Diseases & Disorders of the Digestive System). Its FY 2026 relative weight is 1.5993 with a geometric mean length of stay of 4.2 days.
What is the difference between DRG 393, 394, 395?
All 3 share the same base category; the severity of secondary diagnoses separates them: 393 (with MCC), 394 (with CC), 395 (without CC/MCC). A major complication or comorbidity (MCC) places the case in the highest-weighted DRG of the family; a CC in the middle; neither in the lowest.
How many diagnosis codes group to DRG 393?
575 ICD-10-CM principal diagnosis codes group to this DRG, spanning 61 three-character categories.
What is the relative weight of DRG 393?
The FY 2026 relative weight of this DRG is 1.5993, meaning reimbursement of roughly 1.60 times the average Medicare inpatient case. Multiply by a hospital's blended base rate for the approximate payment.
