TL;DR
MS-DRG 053 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 0.9720 with a geometric mean length of stay of 2.4 days and an arithmetic mean of 3.1. Its weight moved down 0.7% from FY2026 (0.9790). That weight is higher than 20% of all medical and surgical MS-DRGs. Its CC/MCC family (DRG 052) spans weights 0.9720 to 1.7840. The v44 Definitions Manual assigns it through 223 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 053 the FY2027 relative weight is 0.9720 against 0.9790 in FY2026, a fall of 0.72%.
| Metric | FY2026 | FY2027 | Change |
|---|---|---|---|
| Relative weight | 0.9790 | 0.9720 | -0.0070 |
| Geometric mean LOS (days) | 2.6 | 2.4 | -0.2 |
| Arithmetic mean LOS (days) | 3.3 | 3.1 | -0.2 |
CC and MCC family
DRG 053 shares its base definition with 1 other MS-DRG split by severity. The family's weights span 0.9720 to 1.7840, a 1.84× spread, which is the payment effect of documenting qualifying complications and comorbidities.
| DRG | Title | FY2027 weight | GMLOS |
|---|---|---|---|
| 052 | Spinal Disorders and Injuries with CC/MCC | 1.7840 | 4.2 |
| 053 | Spinal Disorders and Injuries without CC/MCC | 0.9720 | 2.4 |
Grouper logic (v44 Definitions Manual)

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 053 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 053
What is MS-DRG 053?
MS-DRG 053 is "Spinal Disorders and Injuries 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 053?
The FY2027 relative weight is 0.9720 (IPPS final rule Table 5, effective October 1, 2026). In FY2026 it was 0.9790, a change of -0.7%.
What is the average length of stay for DRG 053?
CMS reports a geometric mean length of stay of 2.4 days and an arithmetic mean of 3.1 days for FY2027. The geometric mean is used for transfer-payment calculations.
Which DRGs are in the same CC/MCC family as 053?
DRG 052 (Spinal Disorders and Injuries with CC/MCC, weight 1.7840). The family's weights range from 0.9720 to 1.7840, so documented complications and comorbidities change payment materially.
What documentation supports the severity level of DRG 053?
DRG 053 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 053?
The v44 Definitions Manual lists 223 principal diagnosis codes for this group. Examples from the principal diagnosis list: G041 (Tropical spastic paraplegia); G800 (Spastic quadriplegic cerebral palsy); G801 (Spastic diplegic cerebral palsy); G802 (Spastic hemiplegic cerebral palsy).
Is DRG 053 a post-acute transfer DRG?
No. DRG 053 is not on the FY2027 post-acute care transfer list, so the transfer per-diem policy does not apply to it.
