2023 ICD-10-CM Diagnosis Code C86.4
2023 ICD-10-CM Diagnosis Code C86.4
Blastic NK-cell lymphoma
2016 2017 2018 2019 2020 2021 2022 2023 Billable/Specific Code
- C86.4 is a billable/specific ICD-10-CM code that can be used to indicate a diagnosis for reimbursement purposes.
- The 2023 edition of ICD-10-CM C86.4 became effective on October 1, 2022.
- This is the American ICD-10-CM version of C86.4 - other international versions of ICD-10 C86.4 may differ.
Applicable To- Blastic plasmacytoid dendritic cell neoplasm (BPDCN)

Annotation Back-References
In this context, annotation back-references refer to codes that contain:
- Applicable To annotations, or
- Code Also annotations, or
- Code First annotations, or
- Excludes1 annotations, or
- Excludes2 annotations, or
- Includes annotations, or

that may be applicable to
C86.4:
- C00-D49
2023 ICD-10-CM Range C00-D49
NeoplasmsNote- 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).
- C81-C96
2023 ICD-10-CM Range C81-C96
