TL;DR
MS-DRG 724 is a medical group in MDC 12 (Assignment of Diagnosis Codes) at the base severity level of its family. CMS assigns it a FY2027 relative weight of 0.5900 with a geometric mean length of stay of 1.8 days and an arithmetic mean of 2.3. Its weight moved down 10.1% from FY2026 (0.6560). That weight is higher than 1% of all medical and surgical MS-DRGs. Its CC/MCC family (DRG 722, DRG 723) spans weights 0.5900 to 1.6680. The v44 Definitions Manual assigns it through 38 principal diagnosis codes.
What changed from FY2026 to FY2027
CMS recalibrates every MS-DRG weight annually from the prior year's MedPAR claims. For DRG 724 the FY2027 relative weight is 0.5900 against 0.6560 in FY2026, a fall of 10.06%, which exceeds the 2% threshold worth re-checking in contract models.
| Metric | FY2026 | FY2027 | Change |
|---|---|---|---|
| Relative weight | 0.6560 | 0.5900 | -0.0660 |
| Geometric mean LOS (days) | 1.8 | 1.8 | +0.0 |
| Arithmetic mean LOS (days) | 2.1 | 2.3 | +0.2 |
CC and MCC family
DRG 724 shares its base definition with 2 other MS-DRGs split by severity. The family's weights span 0.5900 to 1.6680, a 2.83× spread, which is the payment effect of documenting qualifying complications and comorbidities.
Grouper logic (v44 Definitions Manual)
Principal Diagnosis: 38 ICD-10 codes drive assignment to this group; the first 12 are shown.
| ICD-10 code | Description |

| C600 | Malignant neoplasm of prepuce |
| C601 | Malignant neoplasm of glans penis |
| C602 | Malignant neoplasm of body of penis |
| C608 | Malignant neoplasm of overlapping sites of penis |
| C609 | Malignant neoplasm of penis, unspecified |
| C61 | Malignant neoplasm of prostate |
| C6200 | Malignant neoplasm of unspecified undescended testis |
| C6201 | Malignant neoplasm of undescended right testis |
| C6202 | Malignant neoplasm of undescended left testis |
| C6210 | Malignant neoplasm of unspecified descended testis |
| C6211 | Malignant neoplasm of descended right testis |
| C6212 | Malignant neoplasm of descended left testis |
Documentation and denial exposure
As a medical DRG, assignment depends on the principal diagnosis sequenced from the attending's documentation; a secondary condition sequenced first, or a symptom code in place of the confirmed diagnosis, changes the MDC or the DRG. Because this family splits by severity, auditors target CC and MCC capture: each secondary diagnosis must be documented as present, monitored, evaluated or treated during the stay to survive a DRG-validation review. Typical inpatient denial codes for this group: CARC 16 (claim lacks information needed to group the stay), CARC 50 (the admission or procedure is judged not medically necessary), CARC 97 (a service is bundled into the DRG payment).
How QuickIntell uses DRG 724 data
QuickCode groups inpatient encounters against the current v44 logic, flags CC and MCC candidates that lack supporting documentation, and shows the weight difference across the family before the claim drops. QuickScribe captures the attending's language that supports severity, and QuickRCM works DRG-validation denials with the grouper evidence attached.
Frequently asked questions — DRG 724
What is MS-DRG 724?
MS-DRG 724 is "Malignancy, Male Reproductive System without CC/MCC", a medical Medicare Severity Diagnosis-Related Group in MDC 12, Assignment of Diagnosis Codes. Medicare pays inpatient stays grouped here at the hospital's base rate multiplied by the DRG relative weight.
What is the FY2027 relative weight for DRG 724?
The FY2027 relative weight is 0.5900 (IPPS final rule Table 5, effective October 1, 2026). In FY2026 it was 0.6560, a change of -10.1%.
What is the average length of stay for DRG 724?
CMS reports a geometric mean length of stay of 1.8 days and an arithmetic mean of 2.3 days for FY2027. The geometric mean is used for transfer-payment calculations.
Which DRGs are in the same CC/MCC family as 724?
DRG 722 (Malignancy, Male Reproductive System with MCC, weight 1.6680); DRG 723 (Malignancy, Male Reproductive System with CC, weight 1.0690). The family's weights range from 0.5900 to 1.6680, so documented complications and comorbidities change payment materially.
What documentation supports the severity level of DRG 724?
DRG 724 is the base-severity assignment: no secondary diagnosis on the CC or MCC lists was coded, or the only ones present are excluded for this principal diagnosis. Revenue-integrity review here looks for undercapture, meaning conditions treated during the stay (electrolyte disorders, specified anemia, acute blood loss, pressure injuries present on admission) that were never documented to the specificity the lists require. A compliant query to the attending, not a coder assumption, is the only way to move a stay to the CC or MCC sibling.
Which codes group to DRG 724?
The v44 Definitions Manual lists 38 principal diagnosis codes for this group. Examples from the principal diagnosis list: C600 (Malignant neoplasm of prepuce); C601 (Malignant neoplasm of glans penis); C602 (Malignant neoplasm of body of penis); C608 (Malignant neoplasm of overlapping sites of penis).
Is DRG 724 a post-acute transfer DRG?
No. DRG 724 is not on the FY2027 post-acute care transfer list, so the transfer per-diem policy does not apply to it.
