Gastric surgery
About 43631: Distal partial gastrectomy with duodenal reconnection
Open distal partial gastrectomy with reconnection of the remaining stomach to the duodenum, reported when resection and gastroduodenostomy are performed.
This code describes an open operation removing the distal portion of the stomach and reconnecting the gastric remnant directly to the duodenum. General surgeons and surgical oncologists may perform it for a distal gastric tumor or other disease requiring removal of that portion of the stomach. The reconstruction is commonly called a Billroth I. It is distinct from a more limited excision of a stomach lesion and from removal of the entire stomach.
Report the code when the operative note supports distal partial resection and a gastroduodenostomy. Document the portion removed and the reconstruction performed; a different reconstruction may point to another partial-gastrectomy code. The 90-day global includes 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 a 50% reduction. Assistant-at-surgery payment may be available; co-surgeon payment requires supporting documentation, and team surgery is not permitted. Modifier 50 is inappropriate for this stomach operation.

43631 billing questions
How is this code distinguished from 43632?
This code describes reconnection of the gastric remnant to the duodenum. Code 43632 is for a distal partial gastrectomy reconstructed to the jejunum.
When would 43633 be selected instead?
Use 43633 when the distal partial gastrectomy is reconstructed with a Roux-en-Y configuration rather than a direct connection to the duodenum.
Can a separate lesion excision be reported for the removed stomach?
The gastric resection is integral to this operation. Do not separately report a lesion excision for tissue removed as part of the gastrectomy.
What operative details support reporting this code?
The operative report should establish that the resection was partial and distal, and that the gastric remnant was connected to the duodenum.
How does the 90-day global affect postoperative billing?
The day-before preoperative visit and related postoperative care during the 90-day period are included in the global surgical payment.
Where these rates come from
FeeBase calculates base physician payments from CMS work, practice-expense, and malpractice RVUs, adjusted by each locality’s geographic indices and the applicable conversion factor. Unavailable or separately priced services are labeled rather than assigned a made-up amount.
