TL;DR
MS-DRG 368 is a medical group in MDC 06 (Assignment of Diagnosis Codes) at the highest-severity level of its family. CMS assigns it a FY2027 relative weight of 1.6430 with a geometric mean length of stay of 4.0 days and an arithmetic mean of 5.4. Its weight moved up 3.2% from FY2026 (1.5920). That weight is higher than 50% of all medical and surgical MS-DRGs. Its CC/MCC family (DRG 369, DRG 370) spans weights 0.6740 to 1.6430. The v44 Definitions Manual assigns it through 24 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 368 the FY2027 relative weight is 1.6430 against 1.5920 in FY2026, a rise of 3.20%, which exceeds the 2% threshold worth re-checking in contract models.
| Metric | FY2026 | FY2027 | Change |
|---|---|---|---|
| Relative weight | 1.5920 | 1.6430 | +0.0510 |
| Geometric mean LOS (days) | 4.0 | 4.0 | +0.0 |
| Arithmetic mean LOS (days) | 5.3 | 5.4 | +0.1 |
CC and MCC family
DRG 368 shares its base definition with 2 other MS-DRGs split by severity. The family's weights span 0.6740 to 1.6430, a 2.44× spread, which is the payment effect of documenting qualifying complications and comorbidities.
Grouper logic (v44 Definitions Manual)
Principal Diagnosis: 24 ICD-10 codes drive assignment to this group; the first 12 are shown.

| I8511 | Secondary esophageal varices with bleeding |
| K2081 | Other esophagitis with bleeding |
| K2091 | Esophagitis, unspecified with bleeding |
| K2101 | Gastro-esophageal reflux disease with esophagitis, with bleeding |
| K223 | Perforation of esophagus |
| K226 | Gastro-esophageal laceration-hemorrhage syndrome |

| Q391 | Atresia of esophagus with tracheo-esophageal fistula |
| Q392 | Congenital tracheo-esophageal fistula without atresia |
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 368 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 368
What is MS-DRG 368?
MS-DRG 368 is "Major Esophageal Disorders with MCC", a medical Medicare Severity Diagnosis-Related Group in MDC 06, 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 368?
The FY2027 relative weight is 1.6430 (IPPS final rule Table 5, effective October 1, 2026). In FY2026 it was 1.5920, a change of +3.2%.
What is the average length of stay for DRG 368?
CMS reports a geometric mean length of stay of 4.0 days and an arithmetic mean of 5.4 days for FY2027. The geometric mean is used for transfer-payment calculations.
Which DRGs are in the same CC/MCC family as 368?
DRG 369 (Major Esophageal Disorders with CC, weight 0.9920); DRG 370 (Major Esophageal Disorders without CC/MCC, weight 0.6740). The family's weights range from 0.6740 to 1.6430, so documented complications and comorbidities change payment materially.
What documentation supports the severity level of DRG 368?
DRG 368 requires at least one secondary diagnosis on the CMS Major Complication or Comorbidity list, documented as present and clinically addressed during the stay (monitored, evaluated, treated or extending the stay). Conditions such as acute respiratory failure, severe sepsis or acute kidney injury with specified cause qualify only when the attending's note states the diagnosis itself, not just the lab values. Recovery auditors downgrade this group to the CC or base level when the MCC rests on an unconfirmed query or a resolved historical condition, so the query response and the discharge summary must agree.
Which codes group to DRG 368?
The v44 Definitions Manual lists 24 principal diagnosis codes for this group. Examples from the principal diagnosis list: B3781 (Candidal esophagitis); I8500 (Esophageal varices without bleeding); I8501 (Esophageal varices with bleeding); I8511 (Secondary esophageal varices with bleeding).
Is DRG 368 a post-acute transfer DRG?
No. DRG 368 is not on the FY2027 post-acute care transfer list, so the transfer per-diem policy does not apply to it.
