TL;DR

MS-DRG 712 is a surgical group in MDC 12 (Assignment of Diagnosis Codes) at the base severity level of its family. CMS assigns it a FY2027 relative weight of 1.0810 with a geometric mean length of stay of 2.5 days and an arithmetic mean of 3.0. Its weight moved down 1.7% from FY2026 (1.1000). That weight is higher than 27% of all surgical and medical MS-DRGs. Its CC/MCC family (DRG 711) spans weights 1.0810 to 1.9530. The v44 Definitions Manual assigns it through 647 operating room procedures codes.

What changed from FY2026 to FY2027

CMS recalibrates every MS-DRG weight annually from the prior year's MedPAR claims. For DRG 712 the FY2027 relative weight is 1.0810 against 1.1000 in FY2026, a fall of 1.73%.

CC and MCC family

DRG 712 shares its base definition with 1 other MS-DRG split by severity. The family's weights span 1.0810 to 1.9530, a 1.81× spread, which is the payment effect of documenting qualifying complications and comorbidities.

Documentation and denial exposure

As a surgical DRG, assignment depends on a qualifying operating-room procedure being coded from the operative report; a missing or non-OR procedure code drops the stay into a medical DRG in MDC 12 with a lower weight. 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 712 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 712

What is MS-DRG 712?

MS-DRG 712 is "Testes Procedures without CC/MCC", a surgical 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 712?

The FY2027 relative weight is 1.0810 (IPPS final rule Table 5, effective October 1, 2026). In FY2026 it was 1.1000, a change of -1.7%.

What is the average length of stay for DRG 712?

CMS reports a geometric mean length of stay of 2.5 days and an arithmetic mean of 3.0 days for FY2027. The geometric mean is used for transfer-payment calculations.

Which DRGs are in the same CC/MCC family as 712?

DRG 711 (Testes Procedures with CC/MCC, weight 1.9530). The family's weights range from 1.0810 to 1.9530, so documented complications and comorbidities change payment materially.

What documentation supports the severity level of DRG 712?

DRG 712 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 712?

The v44 Definitions Manual lists 647 operating room procedures codes for this group. Examples from the operating room procedures list: 0V1N07J (Bypass Right Vas Deferens to Right Epididymis with Autologous Tissue Substitute, Open Approach); 0V1N07K (Bypass Right Vas Deferens to Left Epididymis with Autologous Tissue Substitute, Open Approach); 0V1N07N (Bypass Right Vas Deferens to Right Vas Deferens with Autologous Tissue Substitute, Open Approach); 0V1N07P (Bypass Right Vas Deferens to Left Vas Deferens with Autologous Tissue Substitute, Open Approach).

Is DRG 712 a post-acute transfer DRG?

No. DRG 712 is not on the FY2027 post-acute care transfer list, so the transfer per-diem policy does not apply to it.
