Oth types of non-hodg lymph, nodes of axilla and upper limb

This code signifies a diagnosis of a non-Hodgkin lymphoma that doesn't fit into more specific categories, specifically affecting the lymph nodes located in the armpit (axilla) and/or the upper extremities. It indicates a primary or metastatic involvement of these particular lymph node regions by a non-Hodgkin lymphoma type that is not otherwise classified.

Use this code when documentation clearly identifies a non-Hodgkin lymphoma that is specified but not elsewhere classified, and the anatomical site of involvement is explicitly stated as the axillary and/or upper limb lymph nodes. This applies when pathology reports confirm the diagnosis and the physician's notes specify the precise nodal location.

• Ensure the documentation specifies "other specified types" of non-Hodgkin lymphoma, not "unspecified."
• Verify that the anatomical site is explicitly documented as axillary or upper limb lymph nodes.
• Do not use if a more specific type of non-Hodgkin lymphoma (e.g., follicular, diffuse large B-cell) is identified, even if it affects these nodes.
