The ICD-10-CM code C79.00 might also be used to specify conditions or terms like leukemic infiltrate of kidney, malignant melanoma metastatic to kidney, malignant tumor of renal pelvis, metastasis to kidney of unknown primary, metastatic malignant melanoma , metastatic renal cell carcinoma, 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.
The following clinical terms are approximate synonyms or lay terms that might be used to identify the correct diagnosis code:
- Leukemic infiltrate of kidney
- Malignant melanoma metastatic to kidney
- Malignant tumor of renal pelvis
- Metastasis to kidney of unknown primary
- Metastatic malignant melanoma
- Metastatic renal cell carcinoma
- Secondary adenocarcinoma of kidney
- Secondary malignant neoplasm of kidney

Information for Patients
Also called: Hypernephroma, Renal 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
- Blood in your urine
- A lump in your abdomen
- Weight loss for no reason
- Pain in your side that does not go away
- Loss of appetite
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 substances that attack cancer cells without harming normal cells.
