Code Classification

  • Neoplasms
    (C00–D49)
    • Malignant neoplasms of ill-defined, other secondary and unspecified sites
      (C76-C80)
      • Secondary malignant neoplasm of other and unspecified sites
        (C79)

C79.8 is a non-specific and non-billable diagnosis code code, consider using a code with a higher level of specificity for a diagnosis of secondary malignant neoplasm of other specified sites. The code is not specific and is NOT valid for the year 2024 for the submission of HIPAA-covered transactions. Category or Header define the heading of a category of codes that may be further subdivided by the use of 4th, 5th, 6th or 7th characters.

The following anatomical sites found in the Table of Neoplasms reference this diagnosis code given the correct histological behavior: Neoplasm, neoplastic abdomen, abdominal ; Neoplasm, neoplastic abdomen, abdominal cavity ; Neoplasm, neoplastic abdomen, abdominal organ ; Neoplasm, neoplastic abdomen, abdominal viscera ; Neoplasm, neoplastic abdomen, abdominal wall [See Also: Neoplasm, abdomen, wall, skin] connective tissue ; Neoplasm, neoplastic abdominopelvic ; Neoplasm, neoplastic alveolar ridge or process carcinoma ; etc

Specific Coding Applicable to Secondary malignant neoplasm of other specified sites

Non-specific codes like C79.8 require more digits to indicate the appropriate level of specificity. Consider using any of the following ICD-10-CM codes with a higher level of specificity when coding for secondary malignant neoplasm of other specified sites:

  • Use C79.81 for Secondary malignant neoplasm of breast - BILLABLE CODE

  • Use C79.82 for Secondary malignant neoplasm of genital organs - BILLABLE CODE

  • Use C79.89 for Secondary malignant neoplasm of other specified sites - BILLABLE CODE

Table of Neoplasms

This code is referenced 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.

Patient Education


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.
