Malignant neoplasms of lymphoid, hematopoietic and related tissue (C81-C96) ICD-10-CM
The C81–C96 section covers malignant neoplasms of lymphoid, hematopoietic and related tissue with 633 ICD-10-CM diagnosis codes, of which 533 are billable in fiscal year 2026. The section is organized into the 14 code ranges listed below.
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
ICD-10 codes C81 through C96 cover a variety of malignant neoplasms affecting lymphoid, hematopoietic, and related tissues, including different types of lymphomas and leukemias. These codes are essential for specifying cancers such as Hodgkin lymphoma, non-Hodgkin lymphoma, leukemias, and plasma cell neoplasms by subtype and site.
This range uniquely categorizes malignancies like Hodgkin lymphoma (C81) with detailed forms such as nodular lymphocyte predominant and nodular sclerosis types. It also covers follicular lymphomas (C82) and various subtypes of non-follicular lymphomas (C83), including mantle cell lymphoma and Burkitt lymphoma. The section includes mature T/NK-cell lymphomas (C84), distinguishing conditions like mycosis fungoides and Sezary disease. Leukemias are extensively classified, including lymphoid (C91), myeloid (C92), monocytic (C93), and other specified leukemia types, each with codes for remission and relapse. Plasma cell disorders such as multiple myeloma (C90) are also detailed. Additionally, specialized neoplasms like malignant immunoproliferative diseases (C88) and histiocytic sarcomas (C96.A) are included. The use of synonyms—like Hodgkin's disease for Hodgkin lymphoma or Burkitt's lymphoma for Burkitt lymphoma—help clarify coding decisions and support accurate identification of these conditions, facilitating precise clinical documentation and billing.
