ICD-10 Code C83.74 – Burkitt lymphoma, lymph nodes of axilla and upper limb (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code C83.74 – Burkitt lymphoma, lymph nodes of axilla and upper limb
What it is
C83.74 identifies Burkitt lymphoma involving lymph nodes in the axilla and upper limb. Use it when the record specifies this anatomic site and the diagnosis of Burkitt lymphoma.
Clinical signs
Burkitt lymphoma usually presents as a rapidly enlarging mass or lymph node enlargement. Clinical features vary; refer to documentation for the exact nodal site and confirmed pathology.
When to use this code
Use this code when the provider documents Burkitt lymphoma affecting axillary or upper-limb lymph nodes. It is appropriate after biopsy, pathology, or oncology assessment confirms the diagnosis and location. If the site is not specified, check documentation before coding.
Do not use for
Do not use C83.74 for lymphoma in other lymph node regions or for unspecified Burkitt lymphoma. Do not assign it when the chart only mentions a suspected mass without confirmed diagnosis.
Coding tip
Match both the lymphoma type and the exact nodal location in the record before assigning C83.74.
