What 43775 covers

A surgeon performs this bariatric operation through laparoscopic access, removing a substantial portion of the stomach along the greater curvature and shaping the remaining stomach into a narrow tube. It is performed in a hospital operating room for patients undergoing surgical treatment of obesity. Unlike gastric bypass, the operation does not reroute food through a reconstructed small intestine, and it does not place an adjustable gastric band.

Report the code for the laparoscopic sleeve operation documented in the operative report; the note should establish the approach and the stomach resection performed. The 90-day global period includes the day-before preoperative visit and related postoperative care during the following 90 days. For multiple procedures 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-stomach operation. CMS may pay an assistant at surgery; co-surgeon payment requires supporting documentation, and team surgery is not permitted.

This summary was written with AI assistance from CMS physician fee schedule data and checked against the CMS billing rules shown here. Rates on this page come directly from CMS files.

How to choose

43644Gastric bypass
Use 43644 for laparoscopic gastric bypass, which creates a pouch and reroutes the intestine. Code 43775 describes stomach resection to form a sleeve without intestinal rerouting.
43770Gastric band placement
Code 43770 describes laparoscopic placement of an adjustable gastric band. Code 43775 describes removal of stomach tissue and creation of a sleeve, without band placement.
43845Duodenal switch
Code 43845 describes biliopancreatic diversion with duodenal switch. It involves a different intestinal reconstruction from the sleeve procedure reported with 43775.

43775 billing questions

How is this different from laparoscopic gastric bypass?

A sleeve removes part of the stomach and leaves a narrow tube. Gastric bypass creates a stomach pouch and reroutes the intestinal pathway.

Should modifier 50 be reported?

No. The procedure involves one stomach, so a bilateral adjustment and modifier 50 are inappropriate.

What documentation supports reporting this code?

The operative report should establish the laparoscopic approach and describe the stomach resection and sleeve created.

How does the 90-day global period affect related care?

The global period includes the day-before preoperative visit and 90 days of related postoperative care.

Can an assistant or co-surgeon be paid?

CMS may pay an assistant at surgery. Co-surgeon payment requires supporting documentation; team surgery is not permitted.

What happens when another procedure is performed in the same session?

The highest-valued procedure is paid in full, and other procedures are subject to the standard multiple-procedure reduction.

Where these rates come from

FeeBase calculates base physician payments from CMS work, practice-expense and malpractice RVUs, adjusted by each locality’s geographic indexes and the conversion factor. Services without a published rate are labeled, never given a made-up amount. Amounts are Medicare allowed amounts before claim adjustments: not a patient’s bill or a commercial rate.
