C68: Malignant neoplasm of other and unspecified urinary organs

C68.8: Malignant neoplasm: Overlapping lesion of urinary organs

The tissue in the body is made up of cells. With cancer, the cells multiply uncontrollably, which leads to a malignant neoplasm (abnormal growth of tissue) developing. The cancer cells can destroy the healthy tissue and spread throughout the body.

There are 2 kidneys in the body. There is one on each side of the spine just below the ribcage. Each kidney is made up of renal tissue and a renal pelvis. The renal tissue purifies the blood and, by doing so, produces urine. The urine gathers in the renal pelvis. The urinary passages include the ureters, bladder and urethra. Urine flows from both kidneys into the bladder via the ureters. The urethra channels the urine outward from the bladder.

Not every cancer is the same. There are cancers that develop quickly. You may then quickly feel seriously ill. But there are also cancers that progress slowly. You may then feel generally unwell or weak, or even have no symptoms at all to start with. Cancer of the urinary passages or the kidneys can cause various symptoms. For example, you may have blood in the urine.

Please note: This ICD code may also derive from the ICD-O system. If this is the case, there are usually additional letters and numbers in addition to the code. It starts with the letter M, followed by 4 digits and then a slash. There is another digit after the slash.

If it is an ICD-O code, then this does not describe a malignant cancer in all cases. The last digit after the slash gives you more detailed information about this:
