MS-DRG 729 – Other Male Reproductive System Diagnoses with CC/MCC
A Medical DRG in MDC 12 (Diseases & Disorders of the Male Reproductive System). Inpatient cases group to DRG 729 when the ICD-10-CM principal diagnosis is one of the 250 codes listed below and a secondary diagnosis on the CC or MCC lists is present. Its FY 2026 relative weight is 1.0587 with a geometric mean length of stay of 3.1 days.

How a case is assigned to DRG 729
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 CC/MCC → 729; without CC/MCC → 730.

Frequently Asked Questions
What is MS-DRG 729?
MS-DRG 729 (Other Male Reproductive System Diagnoses with CC/MCC) is a medical DRG in MDC 12 (Diseases & Disorders of the Male Reproductive System). Its FY 2026 relative weight is 1.0587 with a geometric mean length of stay of 3.1 days.
What is the difference between DRG 729, 730?
All 2 share the same base category; the severity of secondary diagnoses separates them: 729 (with CC/MCC), 730 (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 729?
250 ICD-10-CM principal diagnosis codes group to this DRG, spanning 31 three-character categories.
What is the relative weight of DRG 729?
The FY 2026 relative weight of this DRG is 1.0587, meaning reimbursement of roughly 1.06 times the average Medicare inpatient case. Multiply by a hospital's blended base rate for the approximate payment.
