About 64620: Intercostal nerve neurolysis
Reports neurolytic treatment of an intercostal nerve, commonly for persistent nerve-related chest wall pain when a temporary block is not the treatment performed.
This service uses a neurolytic agent to intentionally disrupt an intercostal nerve’s ability to transmit pain signals. Pain medicine physicians and anesthesiologists commonly perform it for persistent intercostal neuralgia, including selected cases of post-thoracotomy or postherpetic pain, in an outpatient procedure setting. The target is an intercostal nerve along the chest wall; this is not a routine temporary anesthetic block or a muscle chemodenervation service.
Report the code when the documented procedure supports neurolytic treatment of an intercostal nerve, rather than temporary pain relief from an anesthetic injection. The record should identify the treated nerve and support the neurolytic intervention. Related postoperative visits are included in the 10-day global period. When multiple procedures occur in the same session, the highest-valued procedure is paid in full and other procedures are subject to the standard 50% multiple-procedure reduction. CMS indicates modifier 50 is inappropriate. Assistant-at-surgery services are not paid; co-surgeons and team surgery are not permitted.

64620 billing questions
How is this different from an intercostal nerve block?
This code describes neurolytic treatment intended to disrupt nerve signaling. CPT 64420 describes an anesthetic injection for an intercostal nerve block, a different method and purpose.
Should modifier 50 be used for treatment on both sides?
No. CMS identifies bilateral adjustment as inappropriate for this code; do not append modifier 50.
What documentation supports reporting this service?
Document the intercostal nerve targeted and the neurolytic treatment performed. The record should distinguish the procedure from a temporary anesthetic nerve block.
Are related postoperative visits separately reported?
Related postoperative visits during the 10-day global period are included in the procedure's global payment.
Can an assistant or co-surgeon be reported?
CMS does not pay an assistant at surgery for this code, and co-surgeons and team surgery are not permitted.
