What 64488 covers

A transversus abdominis plane (TAP) block places local anesthetic in the tissue plane between abdominal wall muscles to reduce sensation from the anterior abdominal wall. An anesthesiologist, pain physician, or other qualified clinician may perform the block, often with ultrasound guidance, for perioperative pain control around abdominal surgery. This code identifies a bilateral block delivered by injection rather than through a catheter for continuous infusion.

Report the code when the documented service is a bilateral TAP injection; the record should support the block’s purpose, bilateral performance, and injection technique. Medicare prices the code as bilateral, so modifier 50 does not increase payment. The procedure has a 0-day global period, which includes same-day preoperative and postoperative care. When performed in the same session as other procedures, the highest-valued procedure is paid in full and the others at 50%. Medicare does not pay an assistant at surgery for this service; 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.
