Patient had Exploratory Laparotomy, Sigmoid Colectomy with Takedown of Enterovesicular Fistula and Colostomy. Anesthesiologist performed a TAP block for post operative pain. Which CPT code would I use 64486 (unilateral) or 64488 (bilateral)? Anesthesiologist did not specify LT or RT. Medical record does not specify where the block was placed either. Medicare is requiring a modifier to pay the claim.
