Other Hodgkin lymphoma, lymph nodes of axilla and upper limb

This code signifies a diagnosis of Hodgkin lymphoma that does not fit into other specified categories, specifically affecting the lymph nodes located in the axilla (armpit) and/or the upper limb. This is a type of cancer originating from lymphocytes, characterized by the presence of Reed-Sternberg cells, and in this instance, its primary manifestation is in the regional lymphatics of the arm.

Use this code when documentation confirms a diagnosis of Hodgkin lymphoma, classified as "other" or unspecified subtype, with clear involvement of the axillary or upper limb lymph nodes. This applies when the specific subtype of Hodgkin lymphoma (e.g., nodular sclerosis, mixed cellularity) is not documented, but the anatomical site is precisely identified.

• Ensure the physician documentation explicitly states "Hodgkin lymphoma" and specifies involvement of axillary or upper limb lymph nodes.
• Do not use this code if a more specific subtype of Hodgkin lymphoma (e.g., C81.14, C81.24) is documented, even if the axilla/upper limb is involved.
• Always sequence this code as the primary diagnosis when it is the reason for the encounter, unless another condition is clearly the primary reason for admission or visit.
