2027 ICD-10-CM Diagnosis Code C86Other specified types of T/NK-cell lymphoma
C86 is a non-billable ICD-10-CM category code for other specified types of T/NK-cell lymphoma, so it cannot be submitted on claims. Use a more specific code from this category instead, such as C86.00, C86.01, C86.10, and C86.11.

Specific Coding for Other specified types of T/NK-cell lymphomaOverview
Non-specific codes like C86 require more characters. Use one of these billable codes instead:
C86.0 for Extranodal NK/T-cell lymphoma, nasal type
Use C86.00 for Extranodal NK/T-cell lymphoma, nasal type not having achieved remission
Use C86.01 for Extranodal NK/T-cell lymphoma, nasal type, in remission
C86.1 for Hepatosplenic T-cell lymphoma
Use C86.10 for Hepatosplenic T-cell lymphoma not having achieved remission
Use C86.11 for Hepatosplenic T-cell lymphoma, in remission
C86.2 for Enteropathy-type (intestinal) T-cell lymphoma
Use C86.20 for Enteropathy-type (intestinal) T-cell lymphoma not having achieved remission
Use C86.21 for Enteropathy-type (intestinal) T-cell lymphoma, in remission
C86.3 for Subcutaneous panniculitis-like T-cell lymphoma
Use C86.30 for Subcutaneous panniculitis-like T-cell lymphoma not having achieved remission
Use C86.31 for Subcutaneous panniculitis-like T-cell lymphoma, in remission
C86.4 for Blastic NK-cell lymphoma
Use C86.40 for Blastic NK-cell lymphoma not having achieved remission
Use C86.41 for Blastic NK-cell lymphoma, in remission
C86.5 for Angioimmunoblastic T-cell lymphoma
Use C86.50 for Angioimmunoblastic T-cell lymphoma not having achieved remission
Use C86.51 for Angioimmunoblastic T-cell lymphoma, in remission
C86.6 for Primary cutaneous CD30-positive T-cell proliferations
Use C86.60 for Primary cutaneous CD30-positive T-cell proliferations not having achieved remission
Use C86.61 for Primary cutaneous CD30-positive T-cell proliferations, in remission
Instructional NotesGuidance
Instructions from the official ICD-10-CM Tabular List that apply to C86: 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.
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).

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 C86Overview
What is the ICD-10 code for other specified types of T/NK-cell lymphoma?
C86 is the ICD-10-CM category for other specified types of T/NK-cell lymphoma, but it is a non-billable header: claims need a more specific code from this category, listed on this page.
Is C86 (Other specified types of T/NK-cell lymphoma) a billable code?
No. This is a category header that groups the codes for other specified types of T/NK-cell lymphoma, and headers cannot be submitted on claims. Claims for other specified types of T/NK-cell lymphoma need a more specific code from this category, such as C86.00, C86.01, and C86.10.
Can C86 be reported with a code from C84.7?
Not as a rule. The Excludes1 note on C86 lists "anaplastic large cell lymphoma, ALK negative (C84.7-)". 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).
