Pediatric Coding Alert

Question: Should I code a ring block the same as a dorsal penile nerve block?

Answer: A ring block is a subcutaneous injection of Xylocaine in four spots around the base of the penis to anesthetize it. A dorsal penile block is two injections. Any local infiltration of Xylocaine "blocks" a nerve. Some physicians consider the ring block superior, while others consider the dorsal block superior because it is only two sticks instead of four.
 
A dorsal penile nerve block performed with a circumcision is coded 64450* (Injection, anesthetic agent; other peripheral nerve or branch). You can bill 64450* with 54150 (Circumcision, using clamp or other device; newborn) or 54160 (Circumcision, surgical excision other than clamp, device or dorsal slit; newborn). If performed during a subsequent hospital visit, bill the hospital visit code (99238, Hospital discharge day management; 30 minutes or less; or 99433, Subsequent hospital care, for the E/M of a normal newborn, per day) with modifier -25 (Significant, separately identifiable E/M service by the same physician on the same day of the procedure or other service) appended.
 
Some pediatric groups have been paid for the nerve block by appending modifier -51 (Multiple procedures) to 64450*. This usually means you will be paid 50 percent of the full fee for 64450*. In any event, you should fight the managed care companies that claim the nerve block is bundled with the circumcision.
