Malignant neoplasm of anterior wall of urinary bladder

This code signifies a cancerous tumor originating in the anterior wall of the urinary bladder. It indicates a primary malignancy, meaning the cancer started in this specific location rather than spreading from another site. The tumor involves the tissue lining the front portion of the bladder.

Apply this code when documentation explicitly states a primary malignant neoplasm located on the anterior wall of the urinary bladder. This diagnosis is typically confirmed through biopsy and imaging studies. Use for initial diagnosis and subsequent treatment encounters related to this specific bladder cancer.

• Ensure documentation specifies "anterior wall" to differentiate from other bladder sites.
• Do not use for secondary (metastatic) bladder cancer; a different code for the secondary site would be appropriate.
• Consider sequencing with codes for any associated symptoms or complications, such as hematuria or obstruction.
