C83 is a non-billable ICD-10-CM category code for non-follicular lymphoma, so it cannot be submitted on claims. Use a more specific code from this category instead, such as C83.00, C83.01, C83.02, and C83.03.

Instructional NotesGuidance

Instructions from the official ICD-10-CM Tabular List that apply to C83: 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 non-Hodgkin lymphoma (Z85.72)

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.

From Block C81-C96 Malignant neoplasms of lymphoid, hematopoietic and related tissue applies to 533 codes
  • 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)

Notes

General instructions on how these codes are used.

From Chapter 2 (C00-D49) Neoplasms applies to 1,730 codes
  • 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).

Patient EducationClinical

Lymphoma

Lymphoma is a cancer of a part of the immune system called the lymph system. There are many types of lymphoma. One type is Hodgkin disease. The rest are called non-Hodgkin lymphomas.

Questions About C83Overview

What is the ICD-10 code for non-follicular lymphoma?

C83 is the ICD-10-CM category for non-follicular lymphoma, but it is a non-billable header: claims need a more specific code from this category, listed on this page.

Is C83 (Non-follicular lymphoma) a billable code?

No. This is a category header that groups the codes for non-follicular lymphoma, and headers cannot be submitted on claims. Claims for non-follicular lymphoma need a more specific code from this category, such as C83.00, C83.01, and C83.02.

Can C83 be reported with Z85.72?

Not as a rule. The Excludes1 note on C83 lists "personal history of non-Hodgkin lymphoma (Z85.72)". 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).
