ICD-10-CM Code C78.80

Secondary malignant neoplasm of unspecified digestive organ

Version 2020 Billable Code Neoplasm Malignant Secondary

Valid for Submission

C78.80 is a billable code used to specify a medical diagnosis of secondary malignant neoplasm of unspecified digestive organ. The code is valid for the year 2020 for the submission of HIPAA-covered transactions. The ICD-10-CM code C78.80 might also be used to specify conditions or terms like metastasis to digestive organs or pt4 or t4 : endometrial tumor invades bladder mucosa and/or bowel mucosa.

The following anatomical sites found in the Table of Neoplasms apply to this code given the correct histological behavior: alimentary canal or tract NEC or intestine, intestinal .

Diagnostic Related Groups

The ICD-10 code C78.80 is grouped in the following groups for version MS-DRG V37.0 What are Diagnostic Related Groups?
The Diagnostic Related Groups (DRGs) are a patient classification scheme which provides a means of relating the type of patients a hospital treats. The DRGs divides all possible principal diagnoses into mutually exclusive principal diagnosis areas referred to as Major Diagnostic Categories (MDC).

Table of Neoplasms

The code C78.80 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


Cancer

Cancer begins in your cells, which are the building blocks of your body. Normally, your body forms new cells as you need them, replacing old cells that die. Sometimes this process goes wrong. New cells grow even when you don't need them, and old cells don't die when they should. These extra cells can form a mass called a tumor. Tumors can be benign or malignant. Benign tumors aren't cancer while malignant ones are. Cells from malignant tumors can invade nearby tissues. They can also break away and spread to other parts of the body.

Cancer is not just one disease but many diseases. There are more than 100 different types of cancer. Most cancers are named for where they start. For example, lung cancer starts in the lung, and breast cancer starts in the breast. The spread of cancer from one part of the body to another is called metastasis. Symptoms and treatment depend on the cancer type and how advanced it is. Most treatment plans may include surgery, radiation and/or chemotherapy. Some may involve hormone therapy, immunotherapy or other types of biologic therapy, or stem cell transplantation.
