ICD-10 Code C83.77 – Burkitt lymphoma, spleen (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code C83.77 – Burkitt lymphoma, spleen
What it is
C83.77 identifies Burkitt lymphoma involving the spleen. Use it when the record specifically documents this high-grade B-cell lymphoma in splenic tissue.
Clinical signs
Clinical features vary; refer to documentation. Burkitt lymphoma may present with rapidly enlarging mass, abdominal or splenic involvement, and systemic “B” symptoms, but the spleen must be specifically identified.
When to use this code
Use this code when the provider documents Burkitt lymphoma of the spleen, splenic Burkitt lymphoma, or lymphoma confined to splenic involvement. It is appropriate when pathology, imaging, or the assessment clearly links the diagnosis to the spleen.
If the chart only says Burkitt lymphoma without a site, you should not assume splenic involvement. Check documentation for the exact anatomic location and whether the spleen is the primary or involved site.
Do not use for
Do not use this code for Burkitt lymphoma at another site, unspecified Burkitt lymphoma, or a nonspecific splenic mass without a confirmed diagnosis. Check documentation.
Coding tip
Code the site only when the spleen is explicitly documented; otherwise, select the unspecified or other site code that matches the record.
