C79.00 - Secondary malignant neoplasm of unspecified kidney and renal pelvis

Version 2023
ICD-10:C79.00
Short Description:Secondary malignant neoplasm of unsp kidney and renal pelvis
Long Description:Secondary malignant neoplasm of unspecified kidney and renal pelvis
Status: Valid for Submission
Version:ICD-10-CM 2023
Code Classification:
  • Neoplasms (C00–D48)
    • Malignant neoplasms of ill-defined, other secondary and unspecified sites (C76-C80)
      • Secondary malignant neoplasm of other and unspecified sites (C79)

C79.00 is a billable ICD-10 code used to specify a medical diagnosis of secondary malignant neoplasm of unspecified kidney and renal pelvis. The code is valid during the fiscal year 2023 from October 01, 2022 through September 30, 2023 for the submission of HIPAA-covered transactions.

The following anatomical sites found in the Table of Neoplasms reference the parent code C79.0 of the current diagnosis code given the correct histological behavior: Neoplasm, neoplastic calyx, renal ; Neoplasm, neoplastic junction pelviureteric ; Neoplasm, neoplastic kidney (parenchymal) ; Neoplasm, neoplastic kidney (parenchymal) calyx ; Neoplasm, neoplastic kidney (parenchymal) hilus ; Neoplasm, neoplastic kidney (parenchymal) pelvis ; Neoplasm, neoplastic parenchyma, kidney ; etc

Unspecified diagnosis codes like C79.00 are acceptable when clinical information is unknown or not available about a particular condition. Although a more specific code is preferable, unspecified codes should be used when such codes most accurately reflect what is known about a patient's condition. Specific diagnosis codes should not be used if not supported by the patient's medical record.

Approximate Synonyms

The following clinical terms are approximate synonyms or lay terms that might be used to identify the correct diagnosis code:

Approximate Flag - The approximate mapping means there is not an exact match between the ICD-10 and ICD-9 codes and the mapped code is not a precise representation of the original code.

Table of Neoplasms

The parent code C79.0 of the current diagnosis 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


Kidney Cancer

You have two kidneys. They are fist-sized organs on either side of your backbone above your waist. The tubes inside filter and clean your blood, taking out waste products and making urine. Kidney cancer forms in the lining of tiny tubes inside your kidneys.

Kidney cancer becomes more likely as you age. Risk factors include smoking, having certain genetic conditions, and misusing pain medicines for a long time.

You may have no symptoms at first. They may appear as the cancer grows. See your health care provider if you notice:

Tests to diagnose kidney cancer include blood, urine, and imaging tests. You may also have a biopsy.

Treatment depends on your age, your overall health and how advanced the cancer is. It might include surgery, chemotherapy, or radiation, biologic, or targeted therapies. Biologic therapy boosts your body's own ability to fight cancer. Targeted therapy uses drugs or other substances that attack specific cancer cells with less harm to normal cells.
