What 64467 covers
This code represents a block delivered into a fascial plane in the thoracic region on one side. Thoracic plane blocks, including erector spinae and serratus anterior plane approaches, are used to provide regional analgesia for chest-wall or thoracic procedures and pain. Anesthesia and pain-management clinicians commonly perform them in operating rooms, procedural areas, or other settings where regional blocks are provided. Imaging guidance may be used as part of the block service when performed.
Select this unilateral code only when the documented thoracic block and service circumstance match the code; distinguish it from 64466, the unilateral injection code, and from the bilateral code options. Record the block approach, side, medication delivery, and clinical purpose. CMS assigns a 0-day global period, so same-day preoperative and postoperative care is included. 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% reduction. CMS lists bilateral payment with modifier 50 at 150%. Assistant-at-surgery payment is restricted, and co-surgeons and team surgery are not permitted.

- 64469Thoracic plane blockBilateral continuous catheter
- This is the bilateral NFS-designated sibling. 64467 is the unilateral code.
- 64468Thoracic blockBilateral injection
- This is the bilateral injection-code sibling; 64467 is unilateral and carries the NFS designation.

64467 billing questions
How does 64467 differ from 64466?
Both describe a unilateral thoracic fascial plane block, but 64466 is the injection code. Use 64467 only when the documented service meets its distinct NFS designation.
Which thoracic blocks can be represented by this code?
Thoracic fascial plane approaches include erector spinae and serratus anterior plane blocks. Documentation should identify the approach, thoracic site, and side.
Can the block be reported with the related surgical procedure?
A same-session block and another procedure may be subject to CMS's multiple-procedure reduction: the highest-valued procedure is paid in full and the others at 50%. Same-day preoperative and postoperative care is included in this code's 0-day global period.
What does CMS specify for bilateral reporting?
CMS lists bilateral payment with modifier 50 at 150%. The code family also has bilateral counterparts, so distinguish the documented bilateral service from a unilateral block.
What should the record support?
Document the thoracic fascial plane approach, side, medication delivery, and clinical purpose, along with the details that establish the service's NFS designation.
Can an assistant or co-surgeon be reported?
CMS restricts assistant-at-surgery payment for this code. Co-surgeons and team surgery are not permitted.
