Type 2 Excludes

A type 2 excludes note represents "Not included here". An excludes2 note indicates that the condition excluded is not part of the condition represented by the code, but a patient may have both conditions at the same time. When an Excludes2 note appears under a code, it is acceptable to use both the code and the excluded code together, when appropriate.

About the C81–C96 Code Range

These cancers involve lymphoid tissue, including lymph nodes, blood-forming tissue and related tissue. The categories group lymphomas, plasma cell tumors, leukemias and other malignancies.

The lymphoma categories separate Hodgkin lymphoma (C81), follicular lymphoma (C82) and non-follicular lymphoma (C83). Follicular lymphoma divides by grade and named form. C84 and C86 separate named T/NK-cell lymphomas. C85 and C88 contain other named lymphoma and immunoproliferative disease categories.

C90 separates multiple myeloma from other plasma cell tumors. The leukemia categories distinguish lymphoid (C91), myeloid (C92) and monocytic (C93) forms, then other specified cell types (C94) and unspecified cell types (C95). Their subdivisions name forms such as acute or chronic leukemia. C96 groups other and unspecified malignancies of these tissues, including Langerhans-cell histiocytosis forms distinguished by their distribution.
