Is C83.3 a billable ICD-10-CM code?

No. C83.3 is a non-billable header code. Code to a higher level of specificity using one of its child codes.

Where does C83.3 sit in the tabular list?

Neoplasms (C00-D49), in the block Malignant neoplasms of lymphoid, hematopoietic and related tissue (C81-C96).

What cannot be coded together with C83.3?

C83.3 carries Excludes1 notes, which means the conditions they list can never be coded together with it on the same encounter. Some are written on the categories above C83.3 (C83) and apply to it just the same.

C83.3

C83.3 — Diffuse large B-cell lymphoma

Non-billable headerICD-10-CM

C83.3 is a non-billable header ICD-10-CM code for diffuse large 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.

mediastinal (thymic) large B-cell lymphoma (C85.2-)
mature T/NK-cell lymphomas (C84.-)

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

Excludes1 inherited from the categories above C83.3

These are not written on C83.3, but they bind it: a note on a category applies to every code beneath it. Billing C83.3 with anything listed here is a denial.

Written on C83 — Non-follicular lymphoma

personal history of non-Hodgkin lymphoma (Z85.72)

Other codes that can never be billed with C83.3

These codes carry an Excludes1 note pointing at C83.3. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading C83.3 alone.

C88.4Extranodal marginal zone B-cell lymphoma of mucosa-associated lymphoid tissue [MALT-lymphoma]

Risk adjustment

C83.3 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 history

C83.3 has not changed since FY2024 — no addition, revision or deletion across the three most recent ICD-10-CM releases.

Code to one of these instead C83.3

11 child codes. Green means billable.
