Abdominal cutaneous nerve block 64420
Date: Aug 11, 2021
Question:
Patient presents with flank pain for a nerve block injection, with the abdominal cutaneous nerve entrapped by a muscle of the right flank. Although not specifically documented, this sounds like anterior cutaneous nerve entrapment (ACNES), which would involve the nerve endings of the lower thoracic intercostal nerves. One injection is made into the flank muscle near the entrapped nerve, as demonstrated by injection of contrast and fluoroscopy. Would you recommend 64420 intercostal nerve block for this, or another code like 64450?
