TL;DR

MS-DRG 211 is a surgical group in MDC 05 (Assignment of Diagnosis Codes) at the base severity level of its family. CMS assigns it a FY2027 relative weight of 1.8100 with a geometric mean length of stay of 2.6 days and an arithmetic mean of 3.3. It is new for FY2027, so there is no prior-year weight to compare. That weight is higher than 57% of all surgical and medical MS-DRGs. Its CC/MCC family (DRG 210) spans weights 1.8100 to 3.2660. The v44 Definitions Manual assigns it through 27 operating room procedures codes.

What changed from FY2026 to FY2027

DRG 211 is new in the v44 grouper effective October 1, 2026, so there is no FY2026 weight to compare. Review the FY2027 final rule Table 6 series for the code moves that created it and confirm that your encoder and contract modeling have loaded v44.

CC and MCC family

DRG 211 shares its base definition with 1 other MS-DRG split by severity. The family's weights span 1.8100 to 3.2660, a 1.80× 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 05 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 211 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 211

What is MS-DRG 211?

MS-DRG 211 is "Cardiac Pacemaker Revision or Device Replacement without MCC", a surgical Medicare Severity Diagnosis-Related Group in MDC 05, 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 211?

The FY2027 relative weight is 1.8100 (IPPS final rule Table 5, effective October 1, 2026). The DRG is new for FY2027.

What is the average length of stay for DRG 211?

CMS reports a geometric mean length of stay of 2.6 days and an arithmetic mean of 3.3 days for FY2027. The geometric mean is used for transfer-payment calculations.

Which DRGs are in the same CC/MCC family as 211?

DRG 210 (Cardiac Pacemaker Revision or Device Replacement with MCC, weight 3.2660). The family's weights range from 1.8100 to 3.2660, so documented complications and comorbidities change payment materially.

What documentation supports the severity level of DRG 211?

DRG 211 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 211?

The v44 Definitions Manual lists 27 operating room procedures codes for this group. Examples from the operating room procedures list: 02HK00Z (Insertion of Pressure Sensor Monitoring Device into Right Ventricle, Open Approach); 02HK02Z (Insertion of Monitoring Device into Right Ventricle, Open Approach); 02HK0YZ (Insertion of Other Device into Right Ventricle, Open Approach); 02HK3YZ (Insertion of Other Device into Right Ventricle, Percutaneous Approach).

Is DRG 211 a post-acute transfer DRG?

Yes. CMS flags DRG 211 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.
