Urethral fistula

This code represents an abnormal, epithelial-lined tract connecting the urethra to another anatomical structure, excluding the scrotum or vagina. This condition results in the leakage of urine through an unintended opening, often causing discomfort, infection, and urinary incontinence.

Apply this code when documentation clearly indicates a urethral fistula, such as a urethrocutaneous fistula or a urethral-rectal fistula, that is not specifically urethroscrotal, urethrovaginal, or urethrovesicovaginal. This diagnosis is typically supported by imaging studies (e.g., retrograde urethrogram, cystoscopy) and clinical examination findings.

• Carefully review documentation to differentiate between a urethral fistula and other types of genitourinary fistulas, especially those involving the scrotum or vagina, which have specific Excludes1 codes.
• Ensure the physician's documentation specifies the exact anatomical connection if known (e.g., urethrocutaneous, urethrorectal) to confirm the appropriate use of this general code.
• Do not code this alongside N50.89, N82.1, or N82.1 as per the Excludes1 note.
