Peripheral nerve injection
About 64425: Ilioinguinal and iliohypogastric nerve block
Reports an anesthetic injection targeting the ilioinguinal and/or iliohypogastric nerves for diagnostic evaluation or relief of groin or lower abdominal wall pain.
This service places anesthetic near the ilioinguinal and/or iliohypogastric nerves to evaluate or relieve pain in their distribution. Pain medicine physicians and anesthesiologists commonly perform it for groin or lower abdominal wall pain, including persistent pain after inguinal hernia repair. It may be performed in an office-based pain clinic or a hospital outpatient setting.
Select the code when the documented target is these nerves, rather than another named nerve or an unspecified peripheral nerve branch. The record should identify the nerve target, side, clinical indication, medication injected, and the patient’s response when relevant. CMS assigns a 0-day global period, so same-day preoperative and postoperative care is included. For multiple procedures in one session, the highest-valued procedure is paid in full and the others at 50%. For bilateral service, modifier 50 is paid at 150%. CMS does not pay an assistant at surgery, and does not permit co-surgeons or team surgery for this service.
