2027 ICD-10-CM Diagnosis Code C96Other and unspecified malignant neoplasms of lymphoid, hematopoietic and related tissue
C96 is a non-billable ICD-10-CM category code for other and unspecified malignant neoplasms of lymphoid, hematopoietic and related tissue, so it cannot be submitted on claims. Use a more specific code from this category instead, such as C96.0, C96.20, C96.21, and C96.22.

Specific Coding for Oth & unsp malig neoplm of lymphoid, hematpoetc and rel tissOverview
Non-specific codes like C96 require more characters. Use one of these billable codes instead:
Use C96.0 for Multifocal and multisystemic (disseminated) Langerhans-cell histiocytosis
C96.2 for Malignant mast cell neoplasm
Use C96.20 for Malignant mast cell neoplasm, unspecified
Use C96.21 for Aggressive systemic mastocytosis
Use C96.22 for Mast cell sarcoma
Use C96.29 for Other malignant mast cell neoplasm
Use C96.4 for Sarcoma of dendritic cells (accessory cells)
Use C96.5 for Multifocal and unisystemic Langerhans-cell histiocytosis
Use C96.6 for Unifocal Langerhans-cell histiocytosis
Use C96.9 for Malignant neoplasm of lymphoid, hematopoietic and related tissue, unspecified
Use C96.A for Histiocytic sarcoma
Use C96.Z for Other specified malignant neoplasms of lymphoid, hematopoietic and related tissue
Instructional NotesGuidance
Instructions from the official ICD-10-CM Tabular List that apply to C96: its own notes plus those printed at block C81-C96 and Chapter 2. A note printed at a category, block or chapter applies to every code under it.
Excludes1
Not coded here: the excluded code is never reported together with this one, unless the two conditions are unrelated.
- personal history of other malignant neoplasms of lymphoid, hematopoietic and related tissues (Z85.79)
Excludes2
Not included here: the excluded condition is not part of this code, but a patient may have both, so both codes may be reported.
Notes
General instructions on how these codes are used.
- Functional activity
- All neoplasms are classified in this chapter, whether they are functionally active or not. An additional code from Chapter 4 may be used, to identify functional activity associated with any neoplasm.
- Morphology [Histology]
- Chapter 2 classifies neoplasms primarily by site (topography), with broad groupings for behavior, malignant, in situ, benign, etc. The Table of Neoplasms should be used to identify the correct topography code. In a few cases, such as for malignant melanoma and certain neuroendocrine tumors, the morphology (histologic type) is included in the category and codes.
- Primary malignant neoplasms overlapping site boundaries
- A primary malignant neoplasm that overlaps two or more contiguous (next to each other) sites should be classified to the subcategory/code .8 ('overlapping lesion'), unless the combination is specifically indexed elsewhere. For multiple neoplasms of the same site that are not contiguous, such as tumors in different quadrants of the same breast, codes for each site should be assigned.
- Malignant neoplasm of ectopic tissue
- Malignant neoplasms of ectopic tissue are to be coded to the site mentioned, e.g., ectopic pancreatic malignant neoplasms are coded to pancreas, unspecified (C25.9).

Leukemia
Leukemia is a term for cancers of the blood cells. Leukemia starts in blood-forming tissues such as the bone marrow. Your bone marrow makes the cells which will develop into white blood cells, red blood cells, and platelets. Each type of cell has a different job:

Questions About C96Overview
Is C96 a billable code?
No. This is a category header that groups the codes for other and unspecified malignant neoplasms of lymphoid, hematopoietic and related tissue, and headers cannot be submitted on claims. Claims for other and unspecified malignant neoplasms of lymphoid, hematopoietic and related tissue need a more specific code from this category, such as C96.0, C96.20, and C96.21.
Can C96 be reported with Z85.79?
Not as a rule. The Excludes1 note on C96 lists "personal history of other malignant neoplasms of lymphoid, hematopoietic and related tissues (Z85.79)". An Excludes1 note means the excluded code is never reported together with this one; the only exception is when the two conditions are unrelated to each other (Official Guidelines, Section I.A.12.a).
