Benign neoplasm of lymph nodes

This code signifies the presence of a non-cancerous tumor originating in the lymph nodes. These benign growths are typically slow-growing and do not metastasize to other parts of the body. They are distinct from malignant lymphomas.

Apply this code when documentation confirms a benign neoplasm of any lymph node, such as a benign lymphadenoma. This diagnosis is often established through biopsy and histopathological examination. Use this code when the pathology report explicitly states "benign neoplasm of lymph node."

• Differentiate carefully from malignant lymphomas (e.g., Hodgkin's or non-Hodgkin's lymphoma) which are coded in the 200-202 series.
• Ensure the documentation specifies "benign" to avoid miscoding a malignant condition.
• Do not use for reactive lymphadenopathy or hyperplasia, which are inflammatory conditions and not true neoplasms.
