Hodgkin lymphoma, unsp, lymph nodes of axilla and upper limb

This code signifies an unconfirmed type of Hodgkin lymphoma affecting the lymph nodes located in the armpit and upper arm. It indicates a primary malignant neoplasm of the lymphatic system, specifically localized to these regions, without further histological or clinical specification of the Hodgkin lymphoma subtype.

Use this code when documentation confirms Hodgkin lymphoma involvement of the axillary and/or upper limb lymph nodes, but the specific subtype (e.g., nodular sclerosis, mixed cellularity) is not yet determined or explicitly stated. This code is appropriate for initial diagnoses or when pathology results are pending or inconclusive regarding the exact Hodgkin lymphoma classification.

• Do not use this code if a more specific Hodgkin lymphoma subtype (e.g., C81.14, C81.24) is documented.
• Ensure documentation clearly specifies involvement of axillary and/or upper limb lymph nodes; otherwise, an unspecified site code may be more appropriate.
• Sequence this code as the primary diagnosis when Hodgkin lymphoma is the reason for the encounter, followed by any associated signs, symptoms, or complications.
