ICD-10 Code D41.3 – Neoplasm of uncertain behavior of urethra (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code D41.3 – Neoplasm of uncertain behavior of urethra
What it is
D41.3 identifies a urethral growth whose behavior is uncertain, meaning the pathology is neither clearly benign nor malignant. Use it when the record documents an indeterminate neoplasm of the urethra.
Clinical signs
Clinical features vary; refer to documentation. Urethral masses may be found during evaluation for bleeding, obstruction, dysuria, or a visible lesion, but diagnosis depends on the recorded assessment and pathology.
When to use this code
Use this code when the provider documents a neoplasm of uncertain behavior involving the urethra and the site is clearly identified. It is appropriate for pathology or clinical notes that state uncertain, borderline, or indeterminate behavior without confirming malignancy.
Check documentation if the lesion is described only as a mass, polyp, or tumor without behavior stated. Code the documented anatomic site and avoid assuming benign or malignant status.
Do not use for
Do not use D41.3 for confirmed malignant urethral neoplasms or for benign lesions with clearly documented behavior. If the record is nonspecific, check documentation before assigning this code.
Coding tip
Always confirm both the urethral site and the uncertain behavior in the provider’s documentation before coding D41.3.
