About 43843: Non-VBG gastric restrictive procedure

Reports a gastric-restrictive operation for morbid obesity that limits stomach capacity without gastric bypass and is not vertical-banded gastroplasty.

This code describes an operation for morbid obesity that reduces the stomach’s capacity to restrict food intake, without creating a gastric bypass and without using the vertical-banded gastroplasty technique. A bariatric or general surgeon typically performs the procedure in an operating room. The operative report should identify the procedure actually performed and the changes made to the stomach so the service can be distinguished from bypass, vertical-banded gastroplasty, and revision surgery.

Select this code from the operative technique, not simply from the patient’s obesity diagnosis or the intended weight-loss effect. Documentation should support the indication, anatomy treated, and work performed. CMS assigns a 90-day global period, including the day-before preoperative visit and related postoperative care during that period. 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 multiple-procedure reduction. Assistant-at-surgery and co-surgeon payment may be allowed; team surgery is not permitted under this code’s CMS rules.

43843 billing questions

Can this code be used for a gastric bypass?

No. The service is a restrictive operation without gastric bypass. Choose a bypass code when the operative procedure includes the bypass reconstruction.

What documentation supports reporting 43843?

The operative report should describe the restrictive technique, the stomach anatomy altered, and the indication for surgery. It should make clear that the procedure was neither vertical-banded gastroplasty nor gastric bypass.

How does the 90-day global period affect postoperative billing?

The CMS global period includes the day-before preoperative visit and 90 days of related postoperative care. Those related services are included in the global surgical package.

Can an assistant or co-surgeon be reported?

CMS indicates that assistant-at-surgery payment may be made and that co-surgeons are permitted. Team surgery is not permitted under this code’s CMS rules.

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