MS-DRG 293 – Heart Failure and Shock without CC/MCC
A Medical DRG in MDC 05 (Diseases & Disorders of the Circulatory System). Inpatient cases group to DRG 293 when the ICD-10-CM principal diagnosis is one of the 29 codes listed below and no secondary diagnosis on the CC or MCC lists is present. Its FY 2026 relative weight is 0.5660 with a geometric mean length of stay of 2.1 days.
Severity family
The grouper first assigns the case to MDC 05 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 → 291; with CC → 292; without CC/MCC → 293.

Frequently Asked Questions
What is MS-DRG 293?
MS-DRG 293 (Heart Failure and Shock without CC/MCC) is a medical DRG in MDC 05 (Diseases & Disorders of the Circulatory System). Its FY 2026 relative weight is 0.5660 with a geometric mean length of stay of 2.1 days.
What is the difference between DRG 291, 292, 293?
All 3 share the same base category; the severity of secondary diagnoses separates them: 291 (with MCC), 292 (with CC), 293 (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 293?
29 ICD-10-CM principal diagnosis codes group to this DRG, spanning 5 three-character categories.
What is the relative weight of DRG 293?
The FY 2026 relative weight of this DRG is 0.5660, meaning reimbursement of roughly 0.57 times the average Medicare inpatient case. Multiply by a hospital's blended base rate for the approximate payment.
