AHA Coding Clinic® for ICD-9 - 2007 Issue 4; VOLUMES 1 AND 2 NEW/REVISED CODES
Non-Hodgkin's Lymphomas
Effective October 1, 2007, the title of category 200, Lymphosarcoma and reticulosarcoma, has been revised to read “Lymphosarcoma and reticulosarcoma and other specified malignant tumors of lymphatic tissue.†In addition, category 200 has been expanded to allow for a more current classification of lymphomas based on specific designations of behavior. Category 200 requires a fifth digit to indicate the specific site(s) involved. If the lymph nodes affected include more than one region of the body (e.g., head and thorax, neck and abdomen, axilla and lower limb, upper limb and pelvis), the fifth...

Article Overview
This article explains an ICD-9-CM update to the classification of non-Hodgkin’s lymphomas and outlines several major lymphoma categories. It is useful for coders and clinicians who need a broad understanding of how these malignancies are organized by behavior, tissue type, and anatomic involvement. The article also highlights the general clinical context and treatment approaches associated with the listed lymphoma groups.
Why This Topic Matters
Accurate lymphoma classification affects diagnosis coding, reporting consistency, and communication across oncology, pathology, and billing workflows. This article helps readers understand how the related ICD-9-CM categories were revised and how common lymphoma subtypes are grouped for documentation and coding purposes.
