CPT® Code 75736

Selective or supraselective pelvic angiography is a specialized imaging procedure that allows for the detailed visualization of blood vessels located in the pelvic region. This technique is primarily utilized to diagnose various medical conditions, assess traumatic injuries, or create a vascular map prior to elective surgical interventions or embolization procedures. The pelvic blood vessels originate from the aorta and include several key arteries such as the inferior vesical artery in males, which supplies blood to the base of the bladder and subsequently forms the prostatic artery. Other important vessels include the medial rectal artery, the internal pudendal artery—which supplies blood to the anal muscles and perineum and branches into the dorsal artery of the penis or clitoris, as well as the inferior rectal artery—the inferior gluteal artery, and the uterine artery, which provides blood to the broad ligament, ureter, uterus, uterine tube, ovaries, and vagina, with a branch extending to the vaginal artery. Additionally, the superior rectal artery, median sacral artery, and ovarian artery also traverse into the pelvic area. The angiography procedure employs X-ray guidance along with contrast dye to enhance the visibility of these blood vessels. Access to the vascular system is typically achieved through the femoral artery, where a catheter is carefully advanced up to the aorta and into the targeted pelvic vessels. Once the catheter is positioned, contrast dye is injected into the selected or supraselected vessel(s), allowing for real-time observation of blood flow. The imaging process captures dynamic video and/or still images, providing critical information for diagnosis and treatment planning. At the conclusion of the procedure, the catheter is removed, and the code 75736 encompasses the radiologist's oversight of the angiography, including the interpretation of the results, the generation of a written report, and any necessary consultations with referring physicians regarding the findings and potential follow-up actions.
