MS-DRG 867: OTHER INFECTIOUS AND PARASITIC DISEASES DIAGNOSES WITH MCC
MS-DRG 867 is other infectious and parasitic diseases diagnoses with mcc, in MDC 18 (a medical DRG), at the with-MCC (major complication or comorbidity) level. Its FY2027 relative weight is 2.1859, so a case here pays more than the average Medicare inpatient stay (weight 1.0), with a geometric mean length of stay of 5.30 days. 400 ICD-10-CM principal diagnoses group into MS-DRGs 867–869 under the CMS definitions manual; the most-searched are listed below.

Principal diagnoses that group to MS-DRGs 867–869
From the CMS MS-DRG definitions manual’s principal-diagnosis index: 400 ICD-10-CM codes route here, and the CC/MCC status of the secondary diagnoses decides which of 867–869 the case lands in. The 24 most-searched:
