TL;DR
MS-DRG 014 is a medical group in MDC PRE (Pre-MDC (transplants, tracheostomy, ECMO)) at a single-severity group of its family. CMS assigns it a FY2027 relative weight of 11.7890 with a geometric mean length of stay of 26.0 days and an arithmetic mean of 29.0. Its weight moved down 1.9% from FY2026 (12.0180). That weight is higher than 99% of all medical and surgical MS-DRGs. CMS does not split this group by severity.
What changed from FY2026 to FY2027
CMS recalibrates every MS-DRG weight annually from the prior year's MedPAR claims. For DRG 014 the FY2027 relative weight is 11.7890 against 12.0180 in FY2026, a fall of 1.91%.
| Metric | FY2026 | FY2027 | Change |
|---|---|---|---|
| Relative weight | 12.0180 | 11.7890 | -0.2290 |
| Geometric mean LOS (days) | 25.7 | 26.0 | +0.3 |
| Arithmetic mean LOS (days) | 28.7 | 29.0 | +0.3 |
CC and MCC family
DRG 014 stands alone: CMS does not split this base group by CC or MCC severity, so complication documentation does not move the assignment, although it still affects quality and risk-adjustment reporting.
Grouper logic (v44 Definitions Manual)
The Definitions Manual assigns DRG 014 through the MDC PRE principal-diagnosis table and the absence of a qualifying operating-room procedure rather than a DRG-specific code list. See the manual chapter for MDC PRE.
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 has no severity split, review risk concentrates on medical-necessity of the admission itself and on the two-midnight benchmark. 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 014 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 014
What is MS-DRG 014?
MS-DRG 014 is "Allogeneic Bone Marrow Transplant", a medical Medicare Severity Diagnosis-Related Group in MDC PRE, Pre-MDC (transplants, tracheostomy, ECMO). 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 014?
The FY2027 relative weight is 11.7890 (IPPS final rule Table 5, effective October 1, 2026). In FY2026 it was 12.0180, a change of -1.9%.
What is the average length of stay for DRG 014?
CMS reports a geometric mean length of stay of 26.0 days and an arithmetic mean of 29.0 days for FY2027. The geometric mean is used for transfer-payment calculations.
What documentation supports the severity level of DRG 014?
DRG 014 has no CC or MCC sibling, so secondary-diagnosis capture does not change the group or its weight. Review effort belongs instead on the principal diagnosis sequencing and the procedure codes that place the stay in this group, and on medical necessity of the inpatient admission itself under the two-midnight benchmark, which is where denials for single-severity groups concentrate.
Is DRG 014 a post-acute transfer DRG?
No. DRG 014 is not on the FY2027 post-acute care transfer list, so the transfer per-diem policy does not apply to it.
