CPT 48150 describes a pancreatectomy, proximal subtotal with total duodenectomy, partial gastrectomy, choledochoenterostomy, and gastrojejunostomy, with pancreatojejunostomy. CPT 44130 describes an enteroenterostomy, an anastomosis of the intestine, with or without cutaneous enterostomy, and is designated by CPT as a “separate procedure.”

According to NCCI edits, there is a procedure-to-procedure (PTP) conflict between 44130 and 48150 when performed during the same encounter, which can be bypassed with modifier 59. If a provider routinely performs an enteroenterostomy in conjunction with the Whipple procedure to prevent future bile reflux—a common postoperative complication—is it appropriate to append modifier 59 to 44130?

Given that these procedures are frequently performed together, could the enteroenterostomy be considered an integral component of the Whipple procedure, rather than a distinct, independent, or unrelated service? While the Whipple procedure description does not specifically include an enteroenterostomy, it does involve bile redirection via choledochoenterostomy. The enteroenterostomy similarly aids in bile flow redirection, serving as an additional step to reduce bile reflux.

In light of this, should these procedures be routinely unbundled and billed together?
