Surgery/Urinary System
Question: May code 52500 be reported for surgical treatment of a bladder neck contracture if a #24 resectoscope with a "cold knife" was used?
Answer: There are two options for this type of procedure depending on whether a resection or incision was performed. If the urologist uses a resectoscope and surgically resects tissue, then use CPT code 52500, Transurethral resection of bladder neck (separate procedure). If a knife is used to perform the incision in the bladder neck, use CPT code 52276, Cystourethroscopy with direct vision internal urethrotomy.[/COLOR]
