What 53601 covers
A urologist typically reports this service when dilating a male patient’s urethral stricture during a subsequent treatment session. The clinician passes sounds or urethral dilators through the urethra to widen a narrowed segment, often to address obstructive urinary symptoms related to scar tissue. The service may be performed in an office or facility setting.
Select this code for the subsequent service in the male stricture-dilation family, rather than the family’s initial-service code. Documentation should identify the stricture, the dilation performed, and why this is a subsequent service. CMS assigns a 0-day global period, so same-day preoperative and postoperative care is included. 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-surgeon and team-surgery billing are not permitted.
