Which MS-DRGs does C82.81 group to?

Excludes1 — never code together — inherited from C82

The conditions below can never be reported together with C82.81 on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.

mature T/NK-cell lymphomas (C84.-)
personal history of non-Hodgkin lymphoma (Z85.72)

Excludes2 — not included here — inherited from C81-C96

The conditions below are not part of C82.81, but a patient may have both at the same time. When documentation supports it, C82.81 and the excluded code may both be reported.

Kaposi's sarcoma of lymph nodes (C46.3)
secondary and unspecified neoplasm of lymph nodes (C77.-)
secondary neoplasm of bone marrow (C79.52)
secondary neoplasm of spleen (C78.89)
