Which MS-DRGs does C81.1A group to?

C81.1A sits in MDC 17 and helps define the logic of 3 MS-DRGs (version 44, FY2027). Which one a stay actually groups to also depends on procedures and secondary diagnoses.

  • 820Lymphoma and Leukemia with Major O.R. Procedures with MCCsurgical
  • 821Lymphoma and Leukemia with Major O.R. Procedures with CCsurgical
  • 822Lymphoma and Leukemia with Major O.R. Procedures without CC/MCCsurgical

As a secondary diagnosis, C81.1A is a complication or comorbidity (CC), which can move a stay into a higher-paying DRG.

Excludes1 — never code together — inherited from C81

The conditions below can never be reported together with C81.1A on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.

  • Kaposi's sarcoma of lymph nodes (C46.3)
  • secondary and unspecified neoplasm of lymph nodes (C77.-)
  • secondary neoplasm of bone marrow (C79.52)
