TL;DR

MS-DRG 935 is a medical group in MDC 22 (Assignment of Diagnosis Codes) at a single-severity group of its family. CMS assigns it a FY2027 relative weight of 2.4230 with a geometric mean length of stay of 4.2 days and an arithmetic mean of 6.3. Its weight moved up 17.6% from FY2026 (2.0600). That weight is higher than 71% of all medical and surgical MS-DRGs. CMS does not split this group by severity. The v44 Definitions Manual assigns it through 610 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 935 the FY2027 relative weight is 2.4230 against 2.0600 in FY2026, a rise of 17.62%, which exceeds the 2% threshold worth re-checking in contract models.

CC and MCC family

DRG 935 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)

Principal Diagnosis: 610 ICD-10 codes drive assignment to this group; the first 12 are shown.

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 935 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 935

What is MS-DRG 935?

MS-DRG 935 is "Non-Extensive Burns", a medical 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 935?

The FY2027 relative weight is 2.4230 (IPPS final rule Table 5, effective October 1, 2026). In FY2026 it was 2.0600, a change of +17.6%.

What is the average length of stay for DRG 935?

CMS reports a geometric mean length of stay of 4.2 days and an arithmetic mean of 6.3 days for FY2027. The geometric mean is used for transfer-payment calculations.

What documentation supports the severity level of DRG 935?

DRG 935 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.

Which codes group to DRG 935?

The v44 Definitions Manual lists 610 principal diagnosis codes for this group. Examples from the principal diagnosis list: T2000XA (Burn of unspecified degree of head, face, and neck, unspecified site, initial encounter); T20011A (Burn of unspecified degree of right ear [any part, except ear drum], initial encounter); T20012A (Burn of unspecified degree of left ear [any part, except ear drum], initial encounter); T20019A (Burn of unspecified degree of unspecified ear [any part, except ear drum], initial encounter).

Is DRG 935 a post-acute transfer DRG?

No. DRG 935 is not on the FY2027 post-acute care transfer list, so the transfer per-diem policy does not apply to it.
