Secondary malignant neoplasm of mediastinum

Version 2021

Valid for Submission

ICD-10:C78.1
Short Description:Secondary malignant neoplasm of mediastinum
Long Description:Secondary malignant neoplasm of mediastinum

Code Classification

  • Neoplasms (C00–D48)
    • Malignant neoplasms of ill-defined, other secondary and unspecified sites (C76-C80)
      • Secondary malignant neoplasm of resp and digestive organs (C78)

C78.1 is a billable diagnosis code used to specify a medical diagnosis of secondary malignant neoplasm of mediastinum. The code C78.1 is valid during the fiscal year 2022 from October 01, 2021 through September 30, 2022 for the submission of HIPAA-covered transactions.

The ICD-10-CM code C78.1 might also be used to specify conditions or terms like anterior mediastinum mass, hypopharyngeal tnm finding, malignant neoplasm of anterior mediastinum, malignant neoplasm of posterior mediastinum, mediastinum involved by direct extension of malignant neoplasm , metastasis to mediastinum of unknown primary, etc.

The following anatomical sites found in the Table of Neoplasms apply to this code given the correct histological behavior: mediastinum, mediastinal or mediastinum, mediastinal anterior or mediastinum, mediastinal posterior or substernal .

Table of Neoplasms

The code C78.1 is included in the table of neoplasms by anatomical site. For each site there are six possible code numbers according to whether the neoplasm in question is malignant, benign, in situ, of uncertain behavior, or of unspecified nature. The description of the neoplasm will often indicate which of the six columns is appropriate.

Where such descriptors are not present, the remainder of the Index should be consulted where guidance is given to the appropriate column for each morphological (histological) variety listed. However, the guidance in the Index can be overridden if one of the descriptors mentioned above is present.

Information for Patients


Lung Cancer

What is lung cancer?

Lung cancer is cancer that forms in tissues of the lung, usually in the cells that line the air passages. It is the leading cause of cancer death in both men and women.

There are two main types: small cell lung cancer and non-small cell lung cancer. These two types grow differently and are treated differently. Non-small cell lung cancer is the more common type.

Who is at risk for lung cancer?

Lung cancer can affect anyone, but there are certain factors that raise your risk of getting it:

What are the symptoms of lung cancer?

Sometimes lung cancer does not cause any signs or symptoms. It may be found during a chest x-ray done for another condition.

If you do have symptoms, they may include

How is lung cancer diagnosed?

Your health care provider may use many tools to make a diagnosis:

If you do have lung cancer, your provider will do other tests to find out how far it has spread through the lungs, lymph nodes, and the rest of the body. This is called staging. Knowing the type and stage of lung cancer you have helps your provider decide what kind of treatment you need.

What are the treatments for lung cancer?

For most patients with lung cancer, current treatments do not cure the cancer.

Your treatment will depend on which type of lung cancer you have, how far it has spread, your overall health, and other factors. You may get more than one type of treatment.

The treatments for small cell lung cancer include

The treatments for non-small cell lung cancer include

Can lung cancer be prevented?

Avoiding the risk factors may help to prevent lung cancer:
