MS-DRG 723 – Malignancy, Male Reproductive System with CC
A Medical DRG in MDC 12 (Diseases & Disorders of the Male Reproductive System). Inpatient cases group to DRG 723 when the ICD-10-CM principal diagnosis is one of the 38 codes listed below and a secondary diagnosis on the complication or comorbidity (CC) list is present. Its FY 2026 relative weight is 1.1427 with a geometric mean length of stay of 3.4 days.
Severity family
The grouper first assigns the case to MDC 12 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 → 722; with CC → 723; without CC/MCC → 724.

Frequently Asked Questions
What is MS-DRG 723?
MS-DRG 723 (Malignancy, Male Reproductive System with CC) is a medical DRG in MDC 12 (Diseases & Disorders of the Male Reproductive System). Its FY 2026 relative weight is 1.1427 with a geometric mean length of stay of 3.4 days.
What is the difference between DRG 722, 723, 724?
All 3 share the same base category; the severity of secondary diagnoses separates them: 722 (with MCC), 723 (with CC), 724 (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 723?
38 ICD-10-CM principal diagnosis codes group to this DRG, spanning 8 three-character categories.
What is the relative weight of DRG 723?
The FY 2026 relative weight of this DRG is 1.1427, meaning reimbursement of roughly 1.14 times the average Medicare inpatient case. Multiply by a hospital's blended base rate for the approximate payment.
