CPT code 64517 denotes a superior hypogastric plexus nerve block, an interventional pain-management procedure used to treat chronic pelvic pain refractory to medication. The code is clinically significant because chronic pelvic pain affects a substantial patient population and may require advanced procedures when conservative care fails; superior hypogastric plexus blockade can provide diagnostic and therapeutic benefit, especially in pain related to malignancy, gynecologic conditions, and other persistent pelvic pain syndromes. Nationwide relevance stems from utilization in hospital outpatient departments, ambulatory surgery centers, and specialized interventional pain clinics where image guidance and monitored anesthesia care are routinely available.

Key payers considered in typical coverage discussions include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise clinical context for the procedure, common billing considerations, and expected sites of service. The publication outlines benchmarks and coverage patterns where available, highlights policy updates affecting interventional pain services, and clarifies clinical indications reflected by the code description. The summary equips coding, billing, and clinical teams with a focused reference for documentation needs, site-of-service expectations, and the clinical role of superior hypogastric plexus blockade in managing refractory chronic pelvic pain.
