CPT® Code 52327

The procedure described by CPT® Code 52327 involves cystourethroscopy, which is a minimally invasive diagnostic and therapeutic procedure used to examine the bladder and urethra. During this procedure, a cystourethroscope—a specialized instrument equipped with a camera and light—is inserted through the urethra and advanced into the bladder. This allows the physician to visualize the internal structures of the urinary tract. The procedure includes ureteral catheterization, which may be necessary to access the ureters, the tubes that carry urine from the kidneys to the bladder. A key component of this procedure is the subureteric injection of implant material, which is intended to elevate and narrow the ureteral orifice, thereby providing support to the ureter. This technique is commonly referred to as the subureteral transurethral injection (STING) procedure. An alternative method known as the hydrodistention-implantation technique (HIT) may also be utilized. The procedure typically involves the use of a catheter to drain urine from the bladder, and the bladder is partially filled with fluid to enhance visualization of the ureteral orifice. The physician may employ various techniques for ureteral catheterization, including the use of guidewires or a wireless technique, to ensure accurate placement of the catheter. Following the injection of the implant material, the physician verifies the correct placement before completing the procedure by emptying the bladder and withdrawing the cystourethroscope.
