Lymp-rich Hodgkin lymphoma, nodes of head, face, and neck

This code signifies a specific subtype of Hodgkin lymphoma, characterized by a predominance of lymphocytes, affecting the lymph nodes located in the head, face, or neck regions. It represents a malignant neoplasm originating from B lymphocytes, with distinct histological features.

Apply this code when documentation confirms a pathological diagnosis of lymphocyte-rich Hodgkin lymphoma, and imaging or clinical examination specifies involvement of cervical, supraclavicular, preauricular, or other lymph nodes within the head, face, or neck. This code is appropriate for initial diagnosis and subsequent encounters where the primary site of involvement remains these regions.

• Ensure the pathology report explicitly states "lymphocyte-rich" Hodgkin lymphoma, as other subtypes exist.
• Verify the anatomical site of involvement is precisely documented as head, face, or neck lymph nodes.
• Do not confuse with other Hodgkin lymphoma subtypes or non-Hodgkin lymphomas, which have distinct codes.
