MS-DRG 175: PULMONARY EMBOLISM WITH MCC OR ACUTE COR PULMONALE
MS-DRG 175 is pulmonary embolism with mcc or acute cor pulmonale, in MDC 04 (a medical DRG), at the with-MCC (major complication or comorbidity) level. Its FY2027 relative weight is 1.3652, so a case here pays more than the average Medicare inpatient stay (weight 1.0), with a geometric mean length of stay of 3.70 days. 16 ICD-10-CM principal diagnoses group into MS-DRGs 175–176 under the CMS definitions manual; the most-searched are listed below.

Principal diagnoses that group to MS-DRGs 175–176
From the CMS MS-DRG definitions manual’s principal-diagnosis index: 16 ICD-10-CM codes route here, and the CC/MCC status of the secondary diagnoses decides which of 175–176 the case lands in. The 16 most-searched:
- I26.99Other pulmonary embolism without acute cor pulmonale
- I27.82Chronic pulmonary embolism
- I26.09Other pulmonary embolism with acute cor pulmonale
- I26.94Multiple subsegmental thrombotic pulmonary emboli without acute cor pulmonale
- I26.93Single subsegmental thrombotic pulmonary embolism without acute cor pulmonale
- I26.03Cement embolism of pulmonary artery with acute cor pulmonale
- I26.01Septic pulmonary embolism with acute cor pulmonale
