TL;DR
MS-DRG 928 is a surgical group in MDC 22 (Assignment of Diagnosis Codes) at the middle severity level of its family. CMS assigns it a FY2027 relative weight of 7.6440 with a geometric mean length of stay of 12.9 days and an arithmetic mean of 17.6. Its weight moved up 6.6% from FY2026 (7.1730). That weight is higher than 97% of all surgical and medical MS-DRGs. Its CC/MCC family (DRG 929) spans weights 3.0180 to 7.6440. The v44 Definitions Manual assigns it through 194 principal or secondary diagnosis codes and 376 operating room procedures codes and 39 secondary diagnosis codes.
What changed from FY2026 to FY2027
CMS recalibrates every MS-DRG weight annually from the prior year's MedPAR claims. For DRG 928 the FY2027 relative weight is 7.6440 against 7.1730 in FY2026, a rise of 6.57%, which exceeds the 2% threshold worth re-checking in contract models.

CC and MCC family
DRG 928 shares its base definition with 1 other MS-DRG split by severity. The family's weights span 3.0180 to 7.6440, a 2.53× 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 22 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 928 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 928
What is MS-DRG 928?
MS-DRG 928 is "Full Thickness Burn with Skin Graft or Inhalation Injury with CC/MCC", a surgical Medicare Severity Diagnosis-Related Group in MDC 22, 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 928?
The FY2027 relative weight is 7.6440 (IPPS final rule Table 5, effective October 1, 2026). In FY2026 it was 7.1730, a change of +6.6%.
What is the average length of stay for DRG 928?
CMS reports a geometric mean length of stay of 12.9 days and an arithmetic mean of 17.6 days for FY2027. The geometric mean is used for transfer-payment calculations.
Which DRGs are in the same CC/MCC family as 928?
DRG 929 (Full Thickness Burn with Skin Graft or Inhalation Injury without CC/MCC, weight 3.0180). The family's weights range from 3.0180 to 7.6440, so documented complications and comorbidities change payment materially.
What documentation supports the severity level of DRG 928?
DRG 928 is reached when the stay carries a secondary diagnosis from the CMS Complication or Comorbidity list but none from the MCC list. Common CC captures include chronic kidney disease stage 3 and above, uncontrolled diabetes with manifestations, malnutrition of specified severity and heart failure of a stated type. Each must be documented by the treating clinician and show clinical relevance in the record; a condition listed only in the problem list without assessment is the most frequent reason a CC is removed on audit and the stay drops to the base DRG.
Which codes group to DRG 928?
The v44 Definitions Manual lists 194 principal or secondary diagnosis codes and 376 operating room procedures codes and 39 secondary diagnosis codes for this group. Examples from the principal or secondary diagnosis list: T2030XA (Burn of third degree of head, face, and neck, unspecified site, initial encounter); T20311A (Burn of third degree of right ear [any part, except ear drum], initial encounter); T20312A (Burn of third degree of left ear [any part, except ear drum], initial encounter); T20319A (Burn of third degree of unspecified ear [any part, except ear drum], initial encounter).
Is DRG 928 a post-acute transfer DRG?
No. DRG 928 is not on the FY2027 post-acute care transfer list, so the transfer per-diem policy does not apply to it.
