Which MS-DRGs does C84.6A group to?

- 821Lymphoma and Leukemia with Major O.R. Procedures with CCsurgical
- 822Lymphoma and Leukemia with Major O.R. Procedures without CC/MCCsurgical

Excludes1 — never code together — inherited from C84
The conditions below can never be reported together with C84.6A on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.
- personal history of non-Hodgkin lymphoma (Z85.72)
