MS-DRG 840: LYMPHOMA AND NON-ACUTE LEUKEMIA WITH MCC
MS-DRG 840 is lymphoma and non-acute leukemia with mcc, in MDC 17 (a medical DRG), at the with-MCC (major complication or comorbidity) level. Its FY2027 relative weight is 3.2734, so a case here pays more than the average Medicare inpatient stay (weight 1.0), with a geometric mean length of stay of 6.70 days. 519 ICD-10-CM principal diagnoses group into MS-DRGs 840–842 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 840–842
From the CMS MS-DRG definitions manual’s principal-diagnosis index: 519 ICD-10-CM codes route here, and the CC/MCC status of the secondary diagnoses decides which of 840–842 the case lands in. The 24 most-searched:
- D45Polycythemia vera
- C90.00Multiple myeloma not having achieved remission
- C91.10Chronic lymphocytic leukemia of B-cell type not having achieved remission
