Figure 4.Regarding hardware support, both editions of the operating system come with support for most components. The /6 is used infrequently by pathologists in very few places in the world.įigure 4 shows the correspondence between the behavior code of ICD-O and the different sections of Chapter II of ICD-10. Registries report the behavior of the primary tumor, not the metastic tumor. *Note: Cancer registries throughout the world do not use the /6 behavior code (metastatic). Uncertain behavior of neoplasm of lung (such as carcinoid of uncertain behavior) In situ neoplasm of the lung (such as squamous carcinoma in situ)īenign neoplasm of lung (such as adenoma) Metastatic neoplasm of the lung (such as metastatic seminoma from the testis) Malignant neoplasm of the lung (such as carcinoma) ICD-O Coding of Lung Neoplasms Lung Neoplasm (See Behavior Code) ICD-O also describes the type or morphology of the neoplasm, as shown in Figure 3 an adenocarcinoma of the lung would thus be coded C34.9, M-8140/3, and a squamous cell carcinoma of the lung C34.9, M8070/3. The behavior code, incorporated as the fifth digit in the morphology field, identifies whether the neoplasm is malignant, benign, and so forth. In contrast, ICD-O uses only one set of four characters for topography (based on the malignant neoplasm section of ICD-10) the topography code (C34.9, lung) remains the same for all neoplasms of that site. Figure 2 shows the entry for lung neoplasms.
Appropriate ICD-10 categories for each site of the body are then listed in alphabetic order. The ICD-10 alphabetic index (Vol.3) contains, under the term "neoplasm," a table of five columns with the following headings: Malignant, Secondary or Metastatic, In situ, Benign, Uncertain and Unknown Behavior.
