MS-DRG 378 – Gastrointestinal Hemorrhage with CC
A Medical DRG in MDC 06 (Diseases & Disorders of the Digestive System). Inpatient cases group to DRG 378 when the ICD-10-CM principal diagnosis is one of the 44 codes listed below and a secondary diagnosis on the complication or comorbidity (CC) list is present. Its FY 2026 relative weight is 0.9807 with a geometric mean length of stay of 2.9 days.
Severity family
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 → 377; with CC → 378; without CC/MCC → 379.

Frequently Asked Questions
What is MS-DRG 378?
MS-DRG 378 (Gastrointestinal Hemorrhage with CC) is a medical DRG in MDC 06 (Diseases & Disorders of the Digestive System). Its FY 2026 relative weight is 0.9807 with a geometric mean length of stay of 2.9 days.
What is the difference between DRG 377, 378, 379?
All 3 share the same base category; the severity of secondary diagnoses separates them: 377 (with MCC), 378 (with CC), 379 (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 378?
44 ICD-10-CM principal diagnosis codes group to this DRG, spanning 10 three-character categories.
What is the relative weight of DRG 378?
The FY 2026 relative weight of this DRG is 0.9807, meaning reimbursement of roughly 0.98 times the average Medicare inpatient case. Multiply by a hospital's blended base rate for the approximate payment.
