Burkitt lymphoma, lymph nodes of axilla and upper limb

This code signifies a diagnosis of Burkitt lymphoma, a highly aggressive B-cell non-Hodgkin lymphoma, specifically when it originates in or primarily affects the lymph nodes located in the axilla (armpit) and/or the upper limb. This rapidly growing cancer requires prompt diagnosis and treatment.

Apply this code when documentation clearly states a diagnosis of Burkitt lymphoma with primary involvement or metastasis to the axillary or upper limb lymph nodes. This is typically supported by pathology reports confirming Burkitt lymphoma and imaging or physical exam findings indicating involvement of these specific lymph node regions.

• Ensure the pathology report explicitly confirms Burkitt lymphoma, not another subtype of non-Hodgkin lymphoma.
• Verify the anatomical site of involvement is precisely the axilla and/or upper limb lymph nodes to differentiate from other nodal or extranodal sites.
• Sequence this code as the primary diagnosis when it is the reason for the encounter or hospitalization.
