C83.0 — Small cell B-cell lymphoma
Is C83.0 billable?
No — C83.0 is a non-billable header code. C83.0 groups more specific codes and cannot be submitted on a claim. A valid ICD-10-CM code must be reported at the highest level of specificity available in its branch. Select one of the 11 billable codes beneath C83.0.

How is C83.0 listed in the Alphabetic Index?
These are the routes through the Alphabetic Index that lead to C83.0. They show the wording a clinician may have documented, which often differs from the Tabular description.
- Immunocytoma
- Lymphoma › lymphoplasmacytic (of) (malignant)
- Lymphoma › nodal marginal zone (of) (malignant)
- Lymphoma › non-leukemic variant of B-CLL (of) (malignant)
- Lymphoma › small cell B-cell (of) (malignant)
- Lymphoma › splenic marginal zone (of) (malignant)
Excludes1 — never code together
The conditions below can never be reported together with C83.0 on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.
Inclusion terms
Alternative wording in documentation that is classified to C83.0.
- Lymphoplasmacytic lymphoma
- Nodal marginal zone lymphoma
- Non-leukemic variant of B-CLL
- Splenic marginal zone lymphoma
Excludes1 — never code together — inherited from C83
The conditions below can never be reported together with C83.0 on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.
- personal history of non-Hodgkin lymphoma (Z85.72)
Excludes2 — not included here — inherited from C81-C96
The conditions below are not part of C83.0, but a patient may have both at the same time. When documentation supports it, C83.0 and the excluded code may both be reported.

How long has C83.0 existed?
C83.0 has been in ICD-10-CM since at least FY2016, the earliest fiscal year on record here.
Derived from the official order files for FY2016–FY2026. FY2017 and FY2020 publish no order file, so those years are not covered.
Which codes are confused with C83.0?
ICD-10-CM declares these codes mutually exclusive with C83.0 — exactly one of each pair can be correct for a given encounter.
