Malignant neoplasm of anterior wall of bladder

This code identifies a primary cancerous tumor originating in the anterior wall of the urinary bladder. It signifies a malignant growth specifically located in the front portion of the bladder, which is a common site for bladder cancer.

Apply this code when documentation explicitly states a primary malignant neoplasm of the anterior bladder wall. This is typically supported by pathology reports confirming malignancy and imaging studies or cystoscopy findings specifying the tumor's location within the anterior bladder.

• Ensure the documentation specifies "anterior wall" and not a general bladder location or another specific wall.
• Confirm the neoplasm is primary; use secondary codes for metastatic disease to the bladder.
• Always sequence this code as the primary diagnosis when it is the reason for the encounter or treatment.
