Malignant neoplasm of urethra

This code signifies a primary cancerous tumor originating within the urethra, the tube that carries urine from the bladder out of the body. This malignancy can affect any part of the urethra, from the bladder neck to the external meatus, but excludes tumors specifically arising from the bladder's urethral orifice.

Apply this code when documentation confirms a primary malignant neoplasm of the urethra, such as transitional cell carcinoma, squamous cell carcinoma, or adenocarcinoma. This is appropriate for initial diagnosis, treatment, and follow-up care of urethral cancer. Supporting documentation includes pathology reports, operative reports detailing tumor location, and physician notes.

• Differentiate carefully between urethral cancer and bladder cancer with urethral involvement; the Excludes1 note is critical.
• Ensure the documentation specifies the primary site is the urethra and not a secondary metastasis to the urethra.
• Code any associated symptoms or complications, such as urinary obstruction or hematuria, as secondary diagnoses.
