Primary squamous cell carcinoma of left upper lobe of lung Small cell carcinoma, l upper lobe Squamous cell carcinoma, l upper lobe ICD-10-CM C34.12 is grouped within Diagnostic Related Group (s) (MS-DRG v38.0):
Secondary malignant neoplasm of left lung. C78.02 is a billable/specific ICD-10-CM code that can be used to indicate a diagnosis for reimbursement purposes. The 2020 edition of ICD-10-CM C78.02 became effective on October 1, 2019.
The code for carcinoid tumor of the lung, C7A.090, has no specific site or laterality. Coding example: A patient with cancer in the lower lobe of his left lung presents for lobectomy. Proper coding is: C34.32 Malignant neoplasm of lower lobe, left bronchus or lung.
Subcategories that designated laterality are: The code for carcinoid tumor of the lung, C7A.090, has no specific site or laterality. Coding example: A patient with cancer in the lower lobe of his left lung presents for lobectomy. Proper coding is: C34.32 Malignant neoplasm of lower lobe, left bronchus or lung.
Nonmalignant neoplasms of the lung are classified to code 212.3 for benign, 235.7 for uncertain behavior, and 239.1 for unspecified nature. If the lung cancer is considered a metastatic site—the cancer spread from another organ to the lung—code 197.0 is assigned.

The 2022 edition of ICD-10-CM C79. 9 became effective on October 1, 2021. This is the American ICD-10-CM version of C79.
Metastatic tumors in the lungs are cancers that developed at other places in the body (or other parts of the lungs). They then spread through the bloodstream or lymphatic system to the lungs. It is different than lung cancer that starts in the lungs. Nearly any cancer can spread to the lungs.
51 Secondary malignant neoplasm of bone.
90 Malignant neoplasm of unspecified part of unspecified bronchus or lung.
Metastatic cancer has the same name as the primary cancer. For example, breast cancer that spreads to the lung is called metastatic breast cancer, not lung cancer. It is treated as stage IV breast cancer, not as lung cancer.
ICD-10 code C78. 00 for Secondary malignant neoplasm of unspecified lung is a medical classification as listed by WHO under the range - Malignant neoplasms .
51, C80. 1. If the documentation states the cancer is a metastatic cancer, but does not state the site of the metastasis, the coder will assign a code for the primary cancer, followed by code C79. 9 secondary malignant neoplasm of unspecified site.
Causes. Metastatic tumors in the lungs are cancers that developed at other places in the body (or other parts of the lungs). They then spread through the bloodstream or lymphatic system to the lungs. It is different than lung cancer that starts in the lungs.
Lung carcinomas when detected are most often in a metastatic stage IV. Lung carcinomas metastasize by lymphatic as well as blood vessels.
When Primary Lung Cancer Spreads. Cells from a primary lung cancer tumor can sometimes break off and travel through the bloodstream or the lymphatic system. These cells can settle in other organs or regions of the body and begin to grow new tumors. This process is called metastasis.
Cancer of the lung, squamous cell, stage 1. Cancer of the lung, squamous cell, stage 2. Cancer of the lung, squamous cell, stage 3. Cancer of the lung, squamous cell, stage 4. Cancer, lung, non small cell. Eaton-lambert syndrome due to small cell carcinoma of lung. Eaton-lambert syndrome due to small cell lung cancer.
A primary malignant neoplasm that overlaps two or more contiguous (next to each other) sites should be classified to the subcategory/code .8 ('overlapping lesion'), unless the combination is specifically indexed elsewhere.
