Question: What is a TAP catheter, and what’s the correct way to code for it? Mississippi Subscriber Answer: Providers sometime use transverses abdominis plane (TAP) catheters as an alternative to epidural analgesia after upper abdominal surgery. An anesthesiologist might also use a TAP catheter as an adjunct to their anesthesia during an abdominal laparoscopic procedure. Although TAP catheters have been reported as unlisted procedure codes in the past, in 2015 new codes were added to describe the service laterality and either with or without imaging guidance. If the TAP block is placed for continuous infusion, your code options are: A single TAP block nerve injection may also be reported using several different codes, also depending on the laterality and imaging guidance. That single-injection block is coded with: Tip: Before submitting any of these codes, determine whether your provider inserted the TAP catheter for postoperative pain management or if the physician used the block as part of anesthesia during the surgery. If the catheter was used during the surgery as an adjunct to the anesthesia, you shouldn’t report the block separately. Bonus tip: As all of the TAP codes include imaging guidance, do not report imaging separately.
