TL;DR

MS-DRG 087 is a medical group in MDC 01 (Assignment of Diagnosis Codes) at the base severity level of its family. CMS assigns it a FY2027 relative weight of 0.9220 with a geometric mean length of stay of 2.0 days and an arithmetic mean of 2.3. Its weight moved up 0.8% from FY2026 (0.9150). That weight is higher than 18% of all medical and surgical MS-DRGs. Its CC/MCC family (DRG 085, DRG 086) spans weights 0.9220 to 2.2440. The v44 Definitions Manual assigns it through 119 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 087 the FY2027 relative weight is 0.9220 against 0.9150 in FY2026, a rise of 0.77%.

CC and MCC family

DRG 087 shares its base definition with 2 other MS-DRGs split by severity. The family's weights span 0.9220 to 2.2440, a 2.43× spread, which is the payment effect of documenting qualifying complications and comorbidities.

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 087 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 087

What is MS-DRG 087?

MS-DRG 087 is "Traumatic Stupor and Coma <1 Hour without CC/MCC", a medical Medicare Severity Diagnosis-Related Group in MDC 01, 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 087?

The FY2027 relative weight is 0.9220 (IPPS final rule Table 5, effective October 1, 2026). In FY2026 it was 0.9150, a change of +0.8%.

What is the average length of stay for DRG 087?

CMS reports a geometric mean length of stay of 2.0 days and an arithmetic mean of 2.3 days for FY2027. The geometric mean is used for transfer-payment calculations.

Which DRGs are in the same CC/MCC family as 087?

DRG 085 (Traumatic Stupor and Coma <1 Hour with MCC, weight 2.2440); DRG 086 (Traumatic Stupor and Coma <1 Hour with CC, weight 1.3060). The family's weights range from 0.9220 to 2.2440, so documented complications and comorbidities change payment materially.

What documentation supports the severity level of DRG 087?

DRG 087 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 087?

The v44 Definitions Manual lists 119 principal diagnosis codes for this group. Examples from the principal diagnosis list: S020XXA (Fracture of vault of skull, initial encounter for closed fracture); S020XXB (Fracture of vault of skull, initial encounter for open fracture); S02101A (Fracture of base of skull, right side, initial encounter for closed fracture); S02101B (Fracture of base of skull, right side, initial encounter for open fracture).

Is DRG 087 a post-acute transfer DRG?

Yes. CMS flags DRG 087 under the post-acute care transfer policy, so a discharge to a qualifying post-acute setting before the geometric mean length of stay is paid a per-diem amount rather than the full DRG payment.
