What 64486 covers
This service places local anesthetic into the plane between abdominal wall muscle layers to reduce pain from the abdominal wall on one side. Anesthesiologists, pain physicians, and other qualified clinicians commonly perform the block for perioperative analgesia, including after abdominal operations. The service covers injection rather than delivery through a catheter for continuous infusion; imaging guidance, when used, is included in the block service.
Report 64486 for the unilateral injection service, documenting the side, block site, medication, and clinical purpose. A catheter-based continuous infusion is reported with 64487, while bilateral injection has its own code, 64488. The 0-day global period includes same-day preoperative and postoperative care. 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 modifier 50 payment at 150%; assistant-at-surgery payment is restricted, and co-surgeons and team surgery are not permitted.

64486 billing questions
When should 64486 be chosen instead of 64487?
Use 64486 for a unilateral TAP block delivered by injection. Use 64487 when the service uses a catheter for continuous infusion.
How is a bilateral injection block reported?
Code 64488 specifically describes bilateral TAP block by injection. CMS lists modifier 50 payment at 150% for a bilateral procedure; follow the applicable reporting convention for the service and claim.
Is ultrasound guidance separately reported?
Imaging guidance, when performed for this block, is included in the service rather than separately reported as guidance for the TAP block.
What documentation supports 64486?
Document the unilateral side, injection site, medication, and reason for the block. The record should also support that the service was an injection rather than catheter-based continuous infusion.
Are same-day preoperative and postoperative visits separately included?
The 0-day global period includes same-day preoperative and postoperative care for this procedure.
Can an assistant or co-surgeon be billed for this block?
CMS restricts assistant-at-surgery payment for 64486. Co-surgeons and team surgery are not permitted.
Where these rates come from
FeeBase calculates base physician payments from CMS work, practice-expense and malpractice RVUs, adjusted by each locality’s geographic indexes and the conversion factor. Services without a published rate are labeled, never given a made-up amount. Amounts are Medicare allowed amounts before claim adjustments: not a patient’s bill or a commercial rate.
