Gastrointestinal surgery
About 43820: Stomach-to-jejunum bypass without vagotomy
Reports surgical creation of a stomach-to-jejunum connection without vagotomy, typically to bypass impaired gastric outflow or reconstruct gastrointestinal continuity.
A surgeon creates an anastomosis between the stomach and jejunum, routing gastric contents past the usual outlet and intervening duodenum. General or gastrointestinal surgeons perform this operation in the operating room, commonly for gastric outlet obstruction or when reconstruction requires a stomach-to-small-bowel connection. The operative record should identify the anastomosis and whether vagotomy was performed; the presence of vagotomy distinguishes this service from its paired code.
Report 43820 for the gastrojejunostomy when no vagotomy is performed. Documentation should establish the surgical indication, the stomach-to-jejunum connection, and whether the procedure is an initial construction rather than revision of an existing anastomosis. Medicare assigns a 90-day global period, including the day-before preoperative visit and related postoperative care during that period. For multiple procedures in one session, the highest-valued procedure is paid in full and other procedures are subject to the standard 50% reduction. An assistant at surgery may be paid; co-surgeon payment requires supporting documentation, and team surgery is not permitted.
