ICD-10 Code C68.0 – Malignant neoplasm of urethra (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code C68.0 – Malignant neoplasm of urethra
What it is
C68.0 identifies a malignant tumor arising in the urethra. Use it when the documentation states primary urethral cancer or malignant neoplasm of urethra.
Clinical signs
Clinical features vary; refer to documentation. Commonly reported findings include urinary obstruction, hematuria, urethral mass, dysuria, or urethral discharge, but you should code only what is confirmed.
When to use this code
Use C68.0 when the provider documents a primary malignant neoplasm of the urethra, including suspected or confirmed urethral cancer in the record. It also fits pathology, imaging, or operative documentation that clearly identifies the urethra as the primary site.
Do not use it for nonspecific urinary symptoms or for malignancy in another genitourinary site with urethral involvement. If the primary site is unclear, check documentation before assigning the code.
Do not use for
Do not use C68.0 for benign urethral lesions, inflammation, or urinary tract symptoms without cancer. It is also wrong for secondary or metastatic disease unless the urethra is documented as the primary site.
Coding tip
Confirm the exact anatomic site in the record; “urethral cancer” should map to C68.0 only when the urethra is the primary site.
