Malignant neoplasms of urinary tract (C64-C68)

ICD-10 codes C64 to C68 cover malignant neoplasms affecting various parts of the urinary tract, including the kidneys (except renal pelvis), renal pelvis, ureters, bladder, urethra, and other unspecified urinary organs. These codes are specifically used to identify different types and locations of urinary system cancers.

This set of codes distinguishes cancer types by their precise location within the urinary tract. For example, C64 codes represent malignancies of the kidney (excluding the renal pelvis), with detailed subcodes like C64.1 and C64.2 for right and left kidney involvement. The codes also specify multiple types of kidney cancers including clear cell carcinoma, primary nephroblastoma, and sarcoma. Similarly, C65 and C66 relate to cancers of the renal pelvis and ureters, often capturing transitional cell carcinoma and its variants. The bladder cancers in C67 include malignancies in multiple areas such as the trigone, dome, or bladder neck, with synonyms like transitional cell carcinoma and adenocarcinoma aiding in accurate code selection. Lastly, C68 covers other or unspecified urinary organs including the urethra and paraurethral glands, with codes that account for overlapping sites and less common malignancies.
