TL;DR

MS-DRG 217 is a surgical group in MDC 05 (Assignment of Diagnosis Codes) at the middle severity level of its family. CMS assigns it a FY2027 relative weight of 6.8050 with a geometric mean length of stay of 3.9 days and an arithmetic mean of 5.8. Its weight moved up 3.5% from FY2026 (6.5750). That weight is higher than 96% of all surgical and medical MS-DRGs. Its CC/MCC family (DRG 216, DRG 218) spans weights 6.8050 to 9.8820. The v44 Definitions Manual assigns it through 304 operating room procedures codes.

What changed from FY2026 to FY2027

CMS recalibrates every MS-DRG weight annually from the prior year's MedPAR claims. For DRG 217 the FY2027 relative weight is 6.8050 against 6.5750 in FY2026, a rise of 3.50%, which exceeds the 2% threshold worth re-checking in contract models.

CC and MCC family

DRG 217 shares its base definition with 2 other MS-DRGs split by severity. The family's weights span 6.8050 to 9.8820, a 1.45× 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 217 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 217

What is MS-DRG 217?

MS-DRG 217 is "Cardiac Valve and Other Major Cardiothoracic Procedures with Cardiac Catheterization with CC", 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 217?

The FY2027 relative weight is 6.8050 (IPPS final rule Table 5, effective October 1, 2026). In FY2026 it was 6.5750, a change of +3.5%.

What is the average length of stay for DRG 217?

CMS reports a geometric mean length of stay of 3.9 days and an arithmetic mean of 5.8 days for FY2027. The geometric mean is used for transfer-payment calculations.

Which DRGs are in the same CC/MCC family as 217?

DRG 216 (Cardiac Valve and Other Major Cardiothoracic Procedures with Cardiac Catheterization with MCC, weight 9.8820); DRG 218 (Cardiac Valve and Other Major Cardiothoracic Procedures with Cardiac Catheterization without CC/MCC, weight 6.8050). The family's weights range from 6.8050 to 9.8820, so documented complications and comorbidities change payment materially.

What documentation supports the severity level of DRG 217?

DRG 217 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 217?

The v44 Definitions Manual lists 304 operating room procedures codes for this group. Examples from the operating room procedures list: 024F07J (Creation of Aortic Valve from Truncal Valve using Autologous Tissue Substitute, Open Approach); 024F08J (Creation of Aortic Valve from Truncal Valve using Zooplastic Tissue, Open Approach); 024F0JJ (Creation of Aortic Valve from Truncal Valve using Synthetic Substitute, Open Approach); 024F0KJ (Creation of Aortic Valve from Truncal Valve using Nonautologous Tissue Substitute, Open Approach).

Is DRG 217 a post-acute transfer DRG?

Yes. CMS flags DRG 217 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. It is also a special-pay DRG.
