What 53621 covers
This code applies to a subsequent urethral stricture dilation in a female patient using sounds or dilators to widen the narrowed urethral passage. A urologist typically performs the procedure in an office or outpatient facility. It is distinct from dilation of a female urethra when a urethral stricture is not the condition being treated.
Select the subsequent-service code rather than the initial-service code based on where the dilation falls in the treatment sequence, not the stricture’s severity. Document the stricture, the patient’s anatomy, the dilation performed, and why this was a subsequent service. The 0-day global period includes same-day preoperative and postoperative care. When multiple procedures are performed in the same session, the highest-valued procedure is paid in full and other procedures are subject to the standard 50% multiple-procedure reduction. Modifier 50 is inappropriate; assistant-at-surgery payment is restricted, and co-surgery and team-surgery payment are not permitted.
