Malignant neoplasm of bronchus and lung (C34)
Clinical Information
Adenocarcinoma of Lung - A carcinoma originating in the lung and the most common lung cancer type in never-smokers. Malignant cells exhibit distinct features such as glandular epithelial, or tubular morphology. Mutations in KRAS, EGFR, BRAF, and ERBB2 genes are associated with this cancer.
Pulmonary Blastoma - A malignant neoplasm of the lung composed chiefly or entirely of immature undifferentiated cells (i.e., blast forms) with little or virtually no stroma. (From Stedman, 25th ed)
Instructional Notations
Use Additional Code
The “use additional code” indicates that a secondary code could be used to further specify the patient’s condition. This note is not mandatory and is only used if enough information is available to assign an additional code.
- code to identify:
- exposure to environmental tobacco smoke Z77.22
- exposure to tobacco smoke in the perinatal period P96.81
- history of tobacco dependence Z87.891
- occupational exposure to environmental tobacco smoke Z57.31
- tobacco dependence F17
- tobacco use Z72.0
Type 1 Excludes
A type 1 excludes note is a pure excludes note. It means "NOT CODED HERE!" An Excludes1 note indicates that the code excluded should never be used at the same time as the code above the Excludes1 note. An Excludes1 is used when two conditions cannot occur together, such as a congenital form versus an acquired form of the same condition.
