Malignant neoplasm of bladder (C67)

ICD-10 code C67 and its subcodes specifically classify malignant tumors of the bladder, providing precise categories based on the tumor’s exact location within the bladder. These codes are used to document and track bladder cancer diagnoses and treatments.

The broad code C67 covers all malignant neoplasms of the bladder, while subcodes such as C67.0 through C67.7 identify cancers in particular bladder areas like the trigone, dome, and neck, each associated with synonyms like “primary transitional cell carcinoma” or “adenocarcinoma,” aiding in accurate coding. For example, C67.0 denotes malignant tumors of the trigone of the bladder, including transitional cell carcinoma, and C67.7 is used for malignant neoplasms of the urachus. The code C67.8 refers to tumors overlapping multiple bladder sites, and C67.9 is reserved for unspecified bladder cancers, covering various carcinoma types like sarcomatoid or plasmacytoid urothelial carcinoma. Using these specific ICD-10 codes for bladder cancer ensures detailed reporting and supports clinical decision-making and epidemiological research.
