About 43621: Total gastrectomy with Roux-en-Y reconstruction
Report this service for complete stomach removal followed by Roux-en-Y reconstruction, commonly performed for gastric malignancy or other disease requiring total gastrectomy.
The operation removes the stomach in its entirety and restores continuity by connecting the esophagus to a Roux-en-Y limb of small intestine. General surgeons and surgical oncologists perform it in an operating room, commonly for gastric cancer or other disease requiring complete removal. The documented reconstruction distinguishes this service from total gastrectomy without that configuration or with an intestinal pouch.
Report the code when the operative record supports both complete stomach removal and Roux-en-Y reconstruction; a partial resection or lesion excision is not enough. This major surgery has a 90-day global period, including the day-before preoperative visit and 90 days of related postoperative care. When multiple procedures are performed in the same session, the highest-valued procedure is paid in full and other procedures are subject to the standard 50% reduction. Modifier 50 is inappropriate for this single-organ procedure. Assistant-at-surgery payment may be made; co-surgeon payment requires supporting documentation, and team-surgery payment is not permitted.

43621 billing questions
How is this distinguished from 43620?
Use 43621 when the total gastrectomy includes Roux-en-Y reconstruction. Code 43620 describes total gastrectomy without that reconstruction.
When is 43622 a better fit?
Use 43622 when the total gastrectomy includes formation of an intestinal pouch. The reconstruction documented in the operative report determines the choice.
Can a partial gastrectomy be reported with this code?
No. This code represents removal of the entire stomach; a resection that leaves part of the stomach is represented by an appropriate partial-gastrectomy code.
Should modifier 50 be used?
No. The code represents removal of a single stomach, so modifier 50 is inappropriate.
What postoperative care is included?
The 90-day global period includes the day-before preoperative visit and 90 days of related postoperative care.
Can an assistant or co-surgeon be paid?
Assistant-at-surgery payment may be made. Co-surgeon payment requires supporting documentation; team-surgery payment is not permitted.
