ICD-10 Code C83.79 – Burkitt lymphoma, extranodal and solid organ sites (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code C83.79 – Burkitt lymphoma, extranodal and solid organ sites
What it is
C83.79 identifies Burkitt lymphoma involving extranodal or solid organ sites rather than nodal tissue. Use it when the record specifies this anatomic pattern and Burkitt lymphoma is the confirmed diagnosis.
Clinical signs
Clinical features vary; refer to documentation. Burkitt lymphoma often presents as a rapidly growing mass, with symptoms related to the involved organ or extranodal site.
When to use this code
Use this code when the provider documents Burkitt lymphoma in an extranodal location such as a solid organ or other non-nodal site. It is appropriate when the site is clearly stated and no more specific ICD-10 code is documented. If the chart only says Burkitt lymphoma without site detail, check documentation.
Do not use for
Do not use C83.79 for nodal Burkitt lymphoma or for unspecified lymphoma types. Do not assign it if the record does not confirm an extranodal or solid organ site.
Coding tip
Match the code to the documented site wording exactly, and query if the note does not clearly distinguish extranodal from nodal disease.
