ICD-10 Code C83.70 – Burkitt lymphoma, unspecified site (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code C83.70 – Burkitt lymphoma, unspecified site
What it is
C83.70 identifies Burkitt lymphoma when the medical record does not specify the involved site. It is a high-grade B-cell non-Hodgkin lymphoma, so you should code the diagnosis as documented.
Clinical signs
Clinical features vary; refer to documentation. Burkitt lymphoma often presents as a rapidly enlarging mass, with symptoms depending on the site involved and whether disease is nodal or extranodal.
When to use this code
Use C83.70 when the provider documents Burkitt lymphoma but does not identify a specific anatomic site. This is appropriate for confirmed diagnoses in pathology, oncology, or discharge documentation. If the site is later specified, update the code to match the record.
Do not use for
Do not use this code for suspected lymphoma, lymphoma types other than Burkitt, or cases where a specific site is documented. Check documentation if the record instead names another non-Hodgkin lymphoma subtype.
Coding tip
Code the lymphoma exactly as documented, and query for the site if the record is unclear.
