MS-DRG 842 – Lymphoma and Non-Acute Leukemia without CC/MCC

A Medical DRG in MDC 17 (Myeloproliferative Diseases & Disorders, Poorly Differentiated Neoplasms). Inpatient cases group to DRG 842 when the ICD-10-CM principal diagnosis is one of the 519 codes listed below and no secondary diagnosis on the CC or MCC lists is present. Its FY 2026 relative weight is 1.0104 with a geometric mean length of stay of 2.6 days.

How a case is assigned to DRG 842

The grouper first assigns the case to MDC 17 from the principal diagnosis and finds no qualifying operating-room procedure (this is a Medical DRG; ICD-10-PCS codes do not drive assignment here), then applies the severity split from secondary diagnoses: with MCC → 840; with CC → 841; without CC/MCC → 842.

Frequently Asked Questions

What is MS-DRG 842?

MS-DRG 842 (Lymphoma and Non-Acute Leukemia without CC/MCC) is a medical DRG in MDC 17 (Myeloproliferative Diseases & Disorders, Poorly Differentiated Neoplasms). Its FY 2026 relative weight is 1.0104 with a geometric mean length of stay of 2.6 days.

What is the difference between DRG 840, 841, 842?

All 3 share the same base category; the severity of secondary diagnoses separates them: 840 (with MCC), 841 (with CC), 842 (without CC/MCC). A major complication or comorbidity (MCC) places the case in the highest-weighted DRG of the family; a CC in the middle; neither in the lowest.

How many diagnosis codes group to DRG 842?

519 ICD-10-CM principal diagnosis codes group to this DRG, spanning 23 three-character categories.

What is the relative weight of DRG 842?

The FY 2026 relative weight of this DRG is 1.0104, meaning reimbursement of roughly 1.01 times the average Medicare inpatient case. Multiply by a hospital's blended base rate for the approximate payment.
