Oth non-follic lymphoma, nodes of axilla and upper limb

This code signifies a malignant neoplasm of the lymphatic system, specifically a non-follicular lymphoma type that is not otherwise specified or classifiable as a more specific subtype. The tumor is located within the lymph nodes of the axilla (armpit) and/or the upper limb. This diagnosis indicates a primary lymphatic malignancy affecting these regional lymph nodes.

Use this code when documentation confirms a diagnosis of non-follicular lymphoma, and the primary site of involvement is explicitly stated as the lymph nodes of the axilla or upper limb. This applies to cases where the specific subtype of non-follicular lymphoma is not further identified (e.g., diffuse large B-cell lymphoma, mantle cell lymphoma). Supporting documentation would include pathology reports confirming lymphoma and imaging/clinical notes specifying the affected lymph node regions.

• Ensure the documentation clearly states "non-follicular" and specifies involvement of axillary or upper limb lymph nodes.
• Do not use this code if a more specific subtype of non-follicular lymphoma (e.g., diffuse large B-cell lymphoma) is identified; instead, use the code for that specific subtype.
• Consider sequencing this code after any codes for primary solid tumors if the lymphoma is a secondary malignancy, or as the primary diagnosis if it is the presenting condition.
