How to Code the Active Neoplasm or Cancer 1. Go to the “Table of Neoplasms” in the International Classification of Disease (ICD) coding manual. 2. Find the anatomical site. 3. Choose whether the neoplasm is primary or secondary malignant, in situ, benign, of uncertain behavior, or of unspecified nature or behavior Important!
Malignant neoplasm of ectopic tissue
C79. 9 (Secondary malignant neoplasm of unspecified site) should be assigned when no site is identified for the secondary neoplasm. This is also true if the morphology type is qualified but no site is indicated in the diagnostic. In this case, code the primary neoplasm and C79.
Malignant neoplasm of unspecified part of unspecified bronchus or lung. C34. 90 is a billable/specific ICD-10-CM code that can be used to indicate a diagnosis for reimbursement purposes. The 2022 edition of ICD-10-CM C34.

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.
What Is Malignant Neoplasm of Bronchus and Lung? The term “malignant neoplasm” refers to a malignant cancerous growth. A malignant neoplasm of the bronchus and lung, also known as bronchogenic carcinoma or lung cancer, is a malignant cancer that originates in the bronchi, bronchioles, or other parts of the lung.
ICD-10 code C34. 90 for Malignant neoplasm of unspecified part of unspecified bronchus or lung is a medical classification as listed by WHO under the range - Malignant neoplasms .
(NEE-oh-PLA-zum) An abnormal mass of tissue that forms when cells grow and divide more than they should or do not die when they should. Neoplasms may be benign (not cancer) or malignant (cancer).
A malignant neoplasm (NEE-oh-plaz-um) is another term for a cancerous tumor. The term “neoplasm” refers to an abnormal growth of tissue. The term “malignant” means the tumor is cancerous and is likely to spread (metastasize) beyond its point of origin.
The initial draft hierarchy organizes the neoplasm core set under three main headings (malignant, benign, and uncertain/mixed), with limited cross-listing. Several simplified hierarchies may well be needed; user input will be important in deciding on the most useful organization and scope for these.
1 Malignant (primary) neoplasm, unspecified and C79. 9 Secondary malignant neoplasm of unspecified site. A diagnosis of metastatic cancer not otherwise specified (NOS) is used most often when diagnostic tests were not completed.
If the site of the primary cancer is not documented, the coder will assign a code for the metastasis first, followed by C80. 1 malignant (primary) neoplasm, unspecified. For example, if the patient was being treated for metastatic bone cancer, but the primary malignancy site is not documented, assign C79. 51, C80.
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.
Secondary malignant neoplasm of lung 1 C78.0 should not be used for reimbursement purposes as there are multiple codes below it that contain a greater level of detail. 2 The 2021 edition of ICD-10-CM C78.0 became effective on October 1, 2020. 3 This is the American ICD-10-CM version of C78.0 - other international versions of ICD-10 C78.0 may differ.
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.
lymph node metastases ( C77.0) Secondary malignant neoplasm of respiratory and digestive organs. Clinical Information. Cancer that has spread from the original (primary) tumor to the lung. The spread of cancer to the lung. This may be from a primary lung cancer, or from a cancer at a distant site.
Cancer that has spread from the original (primary) tumor to the lung. The spread of cancer to the lung.
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.
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.
secondary carcinoid tumors ( C 7B.-) secondary neuroendocrine tumors ( C7B.-) Cancer that has spread from the original (primary) tumor to the bone.
Thyroid cancer metastatic to bone. Clinical Information. Cancer that has spread from the original (primary) tumor to the bone. The spread of a malignant neoplasm from a primary site to the skeletal system. The majority of metastatic neoplasms to the bone are carcinomas.
