MS-DRG 868: OTHER INFECTIOUS AND PARASITIC DISEASES DIAGNOSES WITH CC
MS-DRG 868 is other infectious and parasitic diseases diagnoses with cc, in MDC 18 (a medical DRG), at the with-CC (complication or comorbidity) level. Its FY2027 relative weight is 1.0235, so a case here pays more than the average Medicare inpatient stay (weight 1.0), with a geometric mean length of stay of 3.30 days. 400 ICD-10-CM principal diagnoses group into MS-DRGs 867–869 under the CMS definitions manual; the most-searched are listed below.

This DRG is subject to the post-acute care transfer policy: a discharge to a qualifying setting below the mean length of stay is paid per diem rather than in full.
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:
- B99.9Unspecified infectious disease
- B96.5Pseudomonas (aeruginosa) (mallei) (pseudomallei) as the cause of diseases classified elsewhere
- B96.81Helicobacter pylori [H. pylori] as the cause of diseases classified elsewhere
- B96.89Other specified bacterial agents as the cause of diseases classified elsewhere
- A49.02Methicillin resistant Staphylococcus aureus infection, unspecified site
