The DRGs divides all possible principal diagnoses into mutually exclusive principal diagnosis areas referred to as Major Diagnostic Categories (MDC). The diagnosis code C79.00 is grouped in the following groups for version MS-DRG V36.0 applicable from 10/01/2018 through 09/30/2019.

  • 656 - KIDNEY AND URETER PROCEDURES FOR NEOPLASM WITH MCC
  • 657 - KIDNEY AND URETER PROCEDURES FOR NEOPLASM WITH CC
  • 658 - KIDNEY AND URETER PROCEDURES FOR NEOPLASM WITHOUT CC/MCC
  • 659 - KIDNEY AND URETER PROCEDURES FOR NON-NEOPLASM WITH MCC
  • 660 - KIDNEY AND URETER PROCEDURES FOR NON-NEOPLASM WITH CC

Information for Patients


Kidney Cancer

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.

General Equivalence Map Definitions
The ICD-10 and ICD-9 GEMs are used to facilitate linking between the diagnosis codes in ICD-9-CM and the new ICD-10-CM code set. The GEMs are the raw material from which providers, health information vendors and payers can derive specific applied mappings to meet their needs.

  • Approximate Flag - The approximate flag is on, indicating that the relationship between the code in the source system and the code in the target system is an approximate equivalent.
  • No Map Flag - The no map flag indicates that a code in the source system is not linked to any code in the target system.
  • Combination Flag - The combination flag indicates that more than one code in the target system is required to satisfy the full equivalent meaning of a code in the source system.
