C83.0

C83.0 — Small cell B-cell lymphoma

Non-billable headerICD-10-CM

C83.0 is a non-billable header ICD-10-CM code for small cell b-cell lymphoma. It cannot be billed on its own: choose one of the more specific child codes below.

Excludes1 — never code together

These conditions cannot occur together. Billing both on the same encounter is a denial.

chronic lymphocytic leukemia (C91.1)
mature T/NK-cell lymphomas (C84.-)
Waldenström macroglobulinemia (C88.00)

Inclusion terms

Alternative wordings a physician may use in the chart for this same code.

Non-leukemic variant of B-CLL
Splenic marginal zone lymphoma

Other codes that can never be billed with C83.0

These codes carry an Excludes1 note pointing at C83.0. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading C83.0 alone.

C91.1Chronic lymphocytic leukemia of B-cell type
C88.0Waldenstrom macroglobulinemia

Risk adjustment

C83.0 does not map to an HCC and does not risk-adjust under CMS-HCC V28. That is normal — most ICD-10 codes do not. It still needs to be coded correctly; it just will not move a RAF score.

Code to one of these instead C83.0

11 child codes. Green means billable.
